Similar setup, different lighting and method ... wow. And more. Of course.

LuxRender: Roald, lost in thought
DAZ Studtio 3: The Forest God, 2014 version
Bryce 7 Pro: atmospherics over a misty fjord
The raw render, right out of LuxRender, waiting for post work...
Background sky: a sunset about a year ago, from the driveway!
Post work: loads of painting in Photoshop.
Just a quick post today. Have been experimenting, but don't have a lot of time to do a looong post, and the way things are going, if I don't just get down to this and do it, it'll slither on another week before I can get it together. So -- I was really fascinated to work some more with the DAZ Studio raytrace you saw last time: the big question was, would the same set of lights work in Lux? Answer: yes, but. The picture would have been utterly different, though the physical elements (guy, chair, brazier, column, stairs...) were the same. Yes, I could have hammered it into a decent image, but inspiration struck.

I deleted everything except the guy and the chair, then imported a new set -- the Cloisters set, from the DAZ marketplace -- and shipped it into LuxRender, with just one light set, representing the sun at a low angle. Then began a fiddle of epic proportions. I couldn't get the lighting right, within Lux. This one fought me, fang and claw -- it's a long time since I've had a render stand up and fight this way, but eventually I got it. The beauty of LuxRender is, you can let the image "cook" overnight and then come back and fiddle with it in the morning.

Then ... choose a sky to match the brooding flavor of the image, as well as the low sun angle. Eureka! A sunset I photographed from the end of the driveway last year. Perfect. (Now you know why I never go anywhere without at least one camera in the bag or pocket.) Lastly, the part I've really come to enjoy. Post work used to be a chore, but I've started to enjoy painting for its own sake; and there's no dispute about it ... the raw render and the painted version are in different worlds.

The second picture for today is The Forest God, a new version done late last year -- a spin on the original idea  which was uploaded in Feb, 2013. (See the original, for comparison.) Once again, loads of painting on this ... and it's a simple raytrace in good ole DAZ Studio 3. I'd love to render this in Lux -- it has a few inherent problems that have put the job on the back burner, pending solutions.

The third image is a deceptively simple seascape in Bryce 7 Pro. The terrain and the water were dead easy. Then I turned on the atmospherics, and started fiddling about with clouds and haze and mist and sea fog. It's the atmosphere that takes forever to render in any of these landscape programs, and Bryce is no different. Mind you, the final result is well worth it! It ain't Vue, but it's not bad...

One day, I swear, I'll get into Vue. Have you SEEN what people are doing in Vue?! I could show you about a thousand images  that have been posted to various galleries and so on, but I'll just show you one. See this. That's typical of what you can do ... and I long to get into it. Drool, drool.

Visit a Gypsy camp in LuxRender, Bryce and DAZ ... and Smith Micro said to me --

LuxRender: Leon and Roald at the Gypsy camp.
(click to see all images at pinup size)
DAZ Studio raytrace painted in Photoshop:
Roald at the fireside
DAZ Studio raytrace in four "laminated" layers:
Meet Iphigenia ... at the Gypsy camp (Abraxas, Chapter 10)
Bryce 7 Pro: the ruined cenotaph beyond Esketh
Bryce 7 Pro: atmospherics and dawn light:
the foothills on the way into the Blue Mountains

Viewers/readers with somewhat long memories will know what they're looking at right here! Yep. I've been delving into The Forgotten Songs again, since the plot notes, which were lost for upwards of a year and a half (!) turned up unexpectedly. And --

Wow. Going back into Abraxas with the resources of LuxRender and Bryce 7 Pro puts a whole new spin on this stuff. Check out this closeup out at full size, guys (it's 1000 pixels wide), even if you don't click to see the leader shot at full size:


Now, that's LuxRender for you, and I'm impressed. It's 90% of the way to a photograph ... like a still from a movie that doesn't exist. 


-- the render is high-rez enough for the venous map in the hand to show. I usually slap on a venous map, but you often don't see it. The map is a bump map (or displacement map, if you want to go that far) which raises the patterns of the veins in torso, hands, arms, so forth, for an added layer of realism. It's great to see this tiny detail in a render; like the wrinkles in the knuckles, too.

The third render for today -- where you meet Iphigenia (you've actually seen her before ... yep, that's Iphigenia in the underground with Leon, in the intense heat and humidity; ergo, a lotta skin, which is pretty typical of fantasy! (Have you noticed how, in movies, guys are dressed from neck to ankles while gals are flitting around in teeny little costumes? Either he's dying of heat stroke in those clothes, or she's freezing! Anyway, that's Hollywood for you, right?) Where was I? Ah yes --

The third render for today, the big scene at the Gypsy camp with all three characters, is a composite shot. It's actually FOUR renders laminated/layered together, starting with an old Bryce skyscape as the bottom layer, and ending up with the foreground vegetation rendered separately:



You start out with a Bryce sky and use his as the backdrop for a dead-simple background image rendered in DAZ Studio (hint: this can be low-rez; not even raytraced -- doesn't need to be). The shot was done at 3000 x 2000 pixels, shipped into Photoshop, blurred, painted, color balanced etc. Then it was shipped back into DAZ Studio to be used as the background for the middle-ground subjects: two Michael 4s and a Victoria 4, with character morphs, wigs, skin maps and costumes, plus a gypsy wagon (the proper name for which is vardo, incidentally...) and the campfire. Only three lights were set and the scene was raytraced ...which took about seven HOURS, just to render this middle ground. The render was sent to Photoshop to be tweaked and painted; then it was shipped back into DAZ Studio, where it was used as the backdrop for the foreground trees, bushes and grasses. So you had a four-layer render, plus --


-- quite a bit of Photoshop painting with those special brushes, after the fact, to get the teeny little details in. Why would you do the image this way? Because it allowed me to do the whole shot in something like nine hours, including painting. If I'd set out to raytrace the entire scene, all of a piece, it'd have been a 20 or 30 hour render.

Maybe it's just me; do I not have the patience to spend 30 hours on an old fashioned raytrace?! Does anybody have the patience these days? Right now, if we invest that kind of time in something, we expect a LuxRender or Octane image (ie., a photographic result) at the end. Beacause ... wellll, with the best will in the world, if you compare a closeup of the three-character raytrace --

(please view full-size ... it's 1600 pixels wide)
-- with the LuxRender fidelity ... no contest. The raytrace is like storybook art. There's nothing wrong with it. But the stuff coming out of Lux and Octane is generations beyond.

Not long ago, raytracing was the be-all and end-all of 3D rendering on any "civilian" desktop; and when I started this blog, I couldn't even raytrace! If I tried, my Lenovo PC crashed right back to the desktop. Kaboom! Now, just a few years later, we look at a raytrace and wish for more! So --

Just for the fun of it, I tried an experiment, to see just how much one can squeeze out of a DAZ Studio 3 raytrace and some Photoshop painting:



In fact, it's not bad at all, what with the colored point lights, depth of field, and then a whole lot of Photoshop work in post. As artwork goes, it's actually pretty darned nice. But, being human, we're never satisfied, and what we want now is a photo, not a painting! So --

Imagine my joy to get the latest Smith Micro newsletter, entitled "The Future of Poser." Long story short: Poser Pro 11, probably due next year, will have a render engine very like Lux or Octane built in, in addition to the highly-respected Firefly render engine. Built in!! Yowzer. Guess where I'll very probably be going in 2016! The only thing that would keep me from going there would be ... oh, if DAZ Studio 5 came out with a decent interface leaving behind the Donald Duck interface we see in Studio 4, and then the new Reality/LuxRender version is indeed 7x faster, as promised. Then, yep, I'd stay with DAZ and Lux. But you gotta admit, the lure of Poser Pro with a built-in unbiased render engine and the much-vaunted Firefly engine ... it's soooo tempting. Like cherry cheesecake.

A gallery of pinups!

LuxRender: Li with Katana
LuxRender: the Barbarian Queen pinup
DAZ Studio: reclining male nude
Bryce 7 Pro science fiction: Crash!
Bryce 7 Pro: Morning on the Mountains

Once again -- playing catch-up and posting a whole heap of stuff at once ... images done in 2014 and 2015, while life has been too hectic, and too weird, for me to post here regularly. Gotta say, am rather pleased with the work that's been done lately. There's a complexity to even the simplest of these shots; and a great deal was invested in each one, even though sometimes it might be too subtle for you to actually see it. Like this:

Hand-painting hair in Photoshop, over a DAZ Studio render
 I know, I know, I always swore hand painting hair was one thing I wouldn't get into because, frankly, it can take twice as long as the render time to get handsome results. But ... well ... the thing of it is, as I get more and more into LuxRender, I'm just getting used to the fact you have to hand paint the hair in almost every instance, because the render engine makes a DAZ toupee look like a plastic bag whacked onto the model's head. Ack. And here's the rub: once you get used to the results of hand-painted hair on the LuxRender shots, you don't really like the results you often get in DAZ Studio renders! So, what the hey? I'm painting the hair now ... and getting better at it. Check out the image, above, at full-size, see what I mean: this outtake is 1000 pixels wide, cropped right out of the original render --

Half the trick is rendering HEEE-UUGE. The shot was done at 3000 pixels wide to give me enough wiggle space to get in and paint realistic hair! Not too bad, if I do say so myself. In fact, the digital painting is a lot of fun, and the more you do it, the more you get to like it. Once upon a long time ago, I used to get into whatever paint program only to touch up images, where "artifacts" had appeared in the render or photo. Now, the painting aspect is something I enjoy so much, I look forward to it, and use it to add dimensions on top of the original render. Like this:



In the mountainscape, though it doesn't hit you in the eyeballs, there are fourteen layers of subtle painting to get this effect; though in the crash site image, above, it's just the birds, the waves in the background and the smoke rising off the wreck, everything else is in the original Bryce render. The burned hull of the crashed ship was done by replacing the MAT file on the OBJ with a kind of rusty, nasty "old metal" texture. The water in the foreground was done by having a semi-opaque water layer with a foamy texture/material laid over a "ground plane" with a pebbly-sandy texture, so you can "see the bottom" through the water."

In fact, the results you can get in Bryce sometimes rival those you can get in LuxRender. If only Bryce would do realistic trees, I wouldn't be looking at Vue with such longing! But it doesn't, and won't ... well, not without spending about A$60 per 3D tree model, and only being able to load up two or three of these in a scene before Bryce goes whacko and crashes in every direction...

Regarding realistic tree models that Bryce, or any prog, can and will use ... oooh yes, I found 'em. I know where they are: Turbo Squid: Trees. But, as gorgeous as these models are, they're somewhat prohibitively expensive for a hobbyist. You'd have to get at least half a dozen models to get enough variety for your renders to be credible, so you're looking at 6 x $39 ... then remember that the Aussie Dollar is sitting at 72c right now, and going down like the proverbial lead balloon; so the price tag for this little shopping spree would be around A$325! Eep.

Not just at the moment, guys ... also, I have my doubts as to how Bryce 7 Pro will handle such complex models. It (or at least my copy of it, on my platform) is tremendously crash-prone when scenes get complex, with lots of objects. And ... wellll, if I had three or four hundred bucks going spare, I'd get my hybrid boot drive and install Vue instead!

Right now, though, am quite happy with what I'm doing in Bryce. If you just avoid trees, you get very good shots. In fact, it's only the palm trees on the beach that let the Crash! image down a bit. If you look too closely at them, they don't hold up, and if/when I do start buying complex trees, this is one shot I'll re-render to bring it right up to speed with near-photo quality results.

Speaking of photo quality --

3D render or photograph? 
There's something, just something, that says to the human eye, this is a 3D render ... but all it can be, I think, is that the hand, or skin, on the model, above, ain't as bashed up as we humans tend to get. The render itself (LuxRender, obviously), is flawless -- that's the old Michael 4 holding Merlin's Katana model, which was Photoshop-painted after rendering. The Li-with-Katana shot is actually a re-render of an old, old image which appeared on the blog a loooong time ago; so long ago, in fact, I have no idea where the original shot is! Gotta love LuxRender --

Which is not to sell Bryce 7 Pro too short, because there's so much you can do with textures, it starts to be a real pleasure to work with:

Water effects in Bryce 7 Pro
Lichen on rock - texture effects in Bryce 7 Pro
Bryce 7 Pro -- atmospherics: love that skyline, and it's in the
original render, not overpainted. Nice!
Bryce 7 Pro: water effects -- even wet sand on the shore.
Now, if Bryce would only do realistic trees...!

Hey, wet sand right above the waterline! Now, how did I do that?! It was actually fairly easy. Made a little shape, jogged it into place, flattened it right out and jogged it down till it juuuust sits on the sand there; made it very transparent and reflective, and applied a simple water texture. This is so cool ... am having loads of fun with Bryce lately.

More soon -- and am also looking (gasp!) at Abraxas again. For the longest time, I lost the plot notes that laid out the story to Chapter 26! Then, just the other day, they turned up ... and the imagination is sparked again. With any luck, I'll be able to pick up the threads and go on with this. Fingers crossed!

A random chain of images suggests a neat story!

Bryce 7 Pro background; foreground in DAZ Studio;
finished with Photoshop overpainting:
"Archer in the Dawn"
Bryce 7 Pro alien landscape, finished in Photoshop 
LuxRender: portrait in low light
LuxRender: a science fiction pinup
Bryce 7 Pro: Crystal Buddha --
pure art, finished/painted in Photoshop.
Another grab-bag of visual goodies, all over the spectrum from fantasy to sf to pure art ... and as I look at a selection of images like this, part of me wants to daisy-chain them together to make a coherent plot! Am starting to think like a writer, probably because I've actually (don't faint) written a couple of short stories lately! And this is what occurs to me, looking at those images...

Welcome to an alien planet with an evolving culture advanced enough to have developed some very exotic longbow technology. It's a green and lovely forest world, with wide lakes and clear skies ... save for the spaceport area where the offworlders have invited themselves in. The indigenous folk are disgusted by the scorched-earth mess they're making. The spaceport city is under a dome -- the air is so toxic with the fallout from those heavy-lift engines, even the offworlders themselves won't breathe it by choice.

A hundred miles away the locals are faaaar from amused. Their high priestess has access to some very ancient, super-powerful magic/tech from deep in the planet. (Oh, and she's a babe -- that helps, right?)  There's a warrior chieftain who's keen to take the magic and inflict it on the offworlders. (And he's also a babe, which definitely helps, LOL!)

Now the plot really thickens: the offworlders and the locals are the same genetic strand. The local indigenous people are a magickal offshoot of an ancient Buddhist enclave who came out to this planet -- ooooh, three centuries ago, and were abandoned utterly when a virus native to this biosphere looked like it was going to obliterate them ... but one great scientist stayed behind to look for a cure and, discovering the "magic" in the deeps of the planet, stopped the virus.

For twelve generations peace and harmony reigned, before the damn' Earthlings returned to see if the contagion had burned itself out and the planet could be recolonized! Nice of them. Imagine their surprise to find a strapping, healthy population that don't want nuthin' to do with the mother world, because their elders -- being cured by "magickal" means -- are the original people who were abandoned 300 years ago, and still alive to this day, and so furious with the Earthlings for leaving them to die, they'd like to see every spacer from "back there" daubed with strawberry jam and staked out on an anthill!

The elders are talking themselves hoarse (and blue) at the negotiating table ... the young are ready to come out fighting. And thereby hangs to tale!

...hey, that's not bad. I ought to right this stuff down. Hang on -- I just did. Might be able to get an actual story of of this, along the way! Am enjoying writing very much, lately, and every time I see an image, or a pot-luck grab-bag of images like the above, can't help spinning plots...

Speaking of the images --

My favorite (duh) is the warrior chieftain, who was rendered in LuxRender with such fine results, it's mostly the hairdo, toupee, wig, that tips you off that this is a render, not a photo. Let's  take the head out of the shot and have a look at the actual render itself:

Photo ... or 3D render?!
...and one more thing we can do, to blur the line between photo and render is to drop the image into monochrome, and strip in a little bit of film grain:
3D render ... or photo? Same image dropped into
monochrome, with a little film grain added.
I do wish the hair props one can get for Michael 4 were realistic. More and more often these days, I find myself painting the hair ... which is sooo time consuming, even if I was brilliant at it, which, to date, I'm not. Still trying to find my way to full competence there. Practice makes perfect, I  know -- and I don't practice enough! Certainly, painting hair is a chore, and the "rub" is, if you get it 100% right, the result will be invisible. That is to say, people won't see the painting, just the hair.

Makes you run away back to Bryce and render something visually spectacular, where the fruits of your labors are visible, like the domed city from the above SF landscape:

Bryce 7 Pro: SF domes city
Every image, no matter which prog rendered it, lands in Photoshop and, often, Irfanview, for painting and tweaking before it's called "done" and displayed. Sometimes, I like to flip an image left-right, and do unspeakable things to the color pallet, to see what might happen. For the "Archer in the Dawn" piece, I wound up with a blue-green-mauve image I liked almost as much as the warm tones. That's Michael 4 again, obviously; the hair is hand-painted, as is all the vegetation in the foreground, plus the tree and birds. As always, the magic is in the details: it's the little things that make a shot "come alive." Take 'em out, and the actual rendered material is very "flat" indeed.

For the curious: the warrior chieftain is lit with just two lights. One is a very, very soft light simulating the sky behind him, while 90% of the light on the model is coming from the globe in the lamp. In Reality, which is the plugin bridge between LuxRender and DAZ Studio, you can select an object and turn it into a light source. For this piece, I wanted to to a low-light portrait, lit only by the light you can see in the shot. Nice! Same sort of thing in the SF pinup, the high priestess with the magic doohickey that's going to defeat the offworlders: the light source is actually inside the prop ... very nice result all around.

Now, what would the plot have been if I'd picked a different set of random images?!
