Sunset light in Bryce 7 Pro


Sunset light ... Bryce 7 Pro. I could just as easily have titled this piece "My Kingdom for a Bryce Materials Lab tutorial my brain can wrap itself around!" Or, "When will someone model realistic trees for Bryce?"

Parts of this image are really neat...


...and as artwork, it's actually rather nice indeed. But if you were hoping for something photographic -- well, hmmm. So I guess it's a question of "horses for courses." Use Bryce for images where it works really well, something like this:


And use it for SF images, like this:


...and save up for a copy of Vue, with enough plug-in modules to make it interesting! The really odd thing is that Bryce was developed as a landscape generator, and in fact, landscapes are the thing it's least effective at. Or, perhaps it showed enormous promise in its day (up to 10 years ago), but today, with Vue offering vistas like this:

...well, I guess Bryce must take its place among the second or third tier programs -- because there are others that are awesome, like Terragen, and so forth. Oh, I know they're out there! And I also know (and confess) that the Bryce Materials Lab continues to defeat me! But I really do lust for the ability to generate really, really realistic landscapes. I feel a definite attack of Vue coming on. Mind you, it's coming on slowly, because I'll drop between $300 and $500 to get it all together, and I'm not quite so overcome with lust that I'll rush off and do it today!

Soon, though.

A little CG science fiction: Landing Approach ... updated (with the "oopsie" fixed!)

first and third are configured as wallpapers

UPDATED next day -- was anyone sharp-eyed enough to catch the "oopsie" ?? You'd have to have a monitor that was set very, very bright to notice it, but ... I used the wrong image when I was preparing the uploads. There was an "artifact" in the painting that had no business being there. It didn't show on monitors set darker or more contrasty, but it was there! So: re-uploaded, fixed. Now, back to the original post...


Yes, your eyes do not deceive you -- that's Neil Travers. And that's still the "Brad" skinmap dropped onto my face morph ... I ran the experiment to see how the Mitchell skinmap would work out. Nope. It changes the face a great deal, especially around the mouth. So it looks like the Brad skinmap, from H3D, is going to be the one. The only work needed on it, in fact, in the post-painting, is to take some of the ruddy color out of the face, and make the eyebrows a leeetle bit more firm, so I actually did a tiny little bit of painting direct onto the skinmap itself, to lessen the work needed each time we render Neil. Result ... very nice!

This is another piece that was worked up in layers, and is a hybrid between Bryce, DAZ Studio and Photoshop. The whole project started with the city, which gave me the inspiration for the rest:



I call this one "Landing Approach," and I'd guess the city down there is something like Hydralis, or perhaps even Sark. I'd need to refer that question to Mel Keegan, see which of the major cities that play such a large part in the Hellgate books best fits this piece.

If you're into the SF aspect and want to chase up Hellgate, be aware that there is GLBT content in these books -- and there are five volumes (big ones!) to date, with one to go to finish up the series. Just go to Mel Keegan Online and follow your nose. [2023 EDIT: the dot-com web address is defunct as of early this year. For some reason, the system utterly denied access to it, and it could not be renewed. Then some joker bought it as a zombie domain name, and MK would have to buy it back at significant cost. Not going to happen, but the web pages are all still there and still viable. Find MK online in the same place.]

If you're into the artistic aspect and want to know what went into this image: that's Michael 4 wearing a face designed by me, and the GQ Event hair by Neftis, and the Brad skinmap by H3D. The costume is the M4 Classic Trenchcoat (from Renderosity), the M4 Cowboy Jeans and the teeshirt from Stylin' M4 (all from DAZ). The textures have all been changed out to give the costume a new look (let's face it, if you stick to the same textures every time, it looks like the characters never change their clothes). The set is the cockpit of the Vanguard space craft (from DAZ). The background is the Alien City standing set for Bryce, with sky and lighting conditions designed by me; the other spacecraft are OBP models (the Bryce version of OBJ) from the Space Combat Force set. The Bryce part of the image was rendered first at high quality, which took 82 minutes, and painted in Photoshop -- which took about the same amount of time; then this was used as the backdrop for the DAZ Studio render. This isn't even a raytrace! The difference between the raytrace and the deep shadow map render was noticeable ... this was one of the very, very rare occasions when the raytrace was not as good. So I went with the other, shipped it into Photoshop and started painting again. The final image was rendered at 3000 pixels wide, to allow for fine painting. The raytrace took about four minutes and the deep shadow map render took close to forty seconds. Go figure. Painting in Photoshop took about an hour after the final render was complete.

The finished image, and the background as a whole, have been uploaded at 1920 wide, so it ought to be perfect for a wallpaper. I've just set it as the wallpaper on both my 24" widescreen and my 15" laptop, and it looks great. It looks so good, I'm reaching for the Hellgate books, and will pass away a couple of pleasant hours this evening with them ... it's way too hot to do anything much. By the third or fourth day of a 100 degree plus heatwave, you're just about ready to admit defeat!

On another note completely: wahooo!  We watched Black Caviar run at Flemington, this time yesterday ... yesss!!! As the commentator said, "The legend lives on." You know me and horses, through the art you seen on these pages and posts. Like everyone else, I love this particular horse: http://www.blackcaviar.net.au/. She's back ... she's bigger, and she's faster than ever. What's not to love:


...and lastly, still on the subject of horses, I just discovered something called Cavalia. You have to see this to believe it: http://www.cavalia.net/en. Oh, my. 

Back soon -- after the heatwave, I think...

Happy Valentine's, 2013!


The image says all! Happy Valentine's Day, 2013 to all.

The e-card is uploaded at 2000 high, if you'd like to see the details, and it should print out nicely, too. He has rather lovely blue eyes ... and I leave it entirely up to you to pick the gender of the lucky recipient of that bunch of flowers! The sunlight looks so nice on this one ... makes you want to grab a book and a long cool drink, go sit in the shade and enjoy the afternoon. Just an old fashioned raytrace in DAZ Studio, nothing fancy -- and then a bunch of Photoshop painting. Actually, I think the painting took longer than posing and rendering the image! The border was done in Photoshop, and the text object was done in Serif.)

Back tomorrow with some SF and ... stuff.

CG art: Before the Storm



click to see all images at large size...

The other day I was surfing around, looking at the work of folks who're working in Vue, specifically. Their landscapes are awe-inspiring, and Bryce just isn't in the same category. Don't get me wrong -- I do love Bryce, but the results it gives are much better suited to SF work than scenes of, well, Earth. Now, Dave has Vue 10 installed on his computer, but he's strapped for time right now, and not able to do very much with it. Meanwhile, I have the super-powerful system, but it doesn't have Vue, it has Bryce. I got to wondering how much it costs to get a license to run Vue 10 on a second computer, so I can have a bash myself --

You wouldn't believe how hard it is to winkle the info out of the E-on Software site!  They have something called the "floating license" system, for networked computers, and it's more expensive to buy the network license than it is to buy a whole 'nother copy of Vue! I don't think they actually allow for two people on the same desk working in tandem, doing stuff that doesn't involve networking, or network rendering, and what have you.

Short version: if I want to give Vue a go on the powerful system, I'll have to buy a whole new copy -- and I probably will. Eventually. But at risk of sounding like Aragorn, that day is not today. Today (actually yesterday, but who's counting?) I thought, "Fair enough, let's see how far you can drive good ol' DAZ Studio 3 with a landscape."

And you're looking at it. I call it "Before the Storm." Originally, I wanted to make a pure render -- no painting over the image at all. But this soon turned out to be implausible, because the render came up with so many "artifacts" due to overdriven displacement mapping, which is the only way to squeeze this kind of result out of DAZ's very simple method of handling objects. Oh...kay, well, if we're going to be painting, then let's get in there and paint everything else, too. A pound gets you a penny, many of the Vue images I'm looking at from artists around the globe are spritzed up in Photoshop too.

You're seeing three terrain objects: the foreground hill, and the mountain at the right, which is actually two nested terrains with different mapping on both (diffuse, bump and displacement) to get this effect. I added the best of the dead trees from the Gnarly Trees pack, and then imported loads of Flinx's Weeds -- but a lot of the foreground ground cover was actually done by bringing in several dozen shrubs, making them very small and burying 90% of them in the ground. The result is instant ground cover that's very realistic without having to paint anything. The shrubs I used are from PNature (from Renderosity). The two birches on the skyline at left are two iterations of the silver birch from Merlin's Trees pack. The Gnarly Tree has overdriven displacement mapping, to get this effect. No displacement map is supplied with the objects, to I set the bump map as the displacement map too, and pushed it to the max the model will take before it literally comes apart. 

What makes this render "pop" is the lighting. I only have four lights on it: the sun, which is grey-blue (storm light) and way high, with shadows set; two spotlights on the mountain because the terrain is sooooo far away in order to look realistic; and the fourth spotlight is right above the tree, and set to be golden yellow ... it casts shadows from the branches and gives a lovely illusion of a single patch of sunlight -- sun between the lowering clouds -- as the storm comes in.

The sky was done from a digital image I captured during rough weather on the Limestone Coast, this time last year. The picture was darkened, contrast was tweaked, everything color saturated, and then resized so that the bottom third was blank, which pushed the interesting part of the sky up, making it appear above the line of the hill here. Brighter clouds and mist were painted over in Photoshop, and one of the things that worked really well was a scarlet cast painted into the sky and given a "saturation" merge mode: the cast doesn't even show in the sky, but the red hits the tree, makes it look like angry evening sun -- a violent sunset just beginning right behind the virtual camera -- on the branches.

The other thing that adds oodles of realism to the mountain is that I put in an atmospheric plane between us and it. You make a primitive, swing it through -90 degrees so it's standing up like a wall, tell it to be blue-green-gray and about 30% opaque, and hit "render." Cool. An atmospheric plane makes anything behind it paler and less contrasty, so the sky image had to be waaaay dark, and very contrasty, to overcome this. But the result is very good, and it's a dead simple technique that gives you the "mountains blued by distance" effect.

The Millennium Horse is wearing the dappled gray texture from the CWRW Pro Textures pack; I fiddled with the morphs to make him look like something a little like an Arabian ... and since I was painting everything in sight, I hand-painted his mane and tail as well, to give a good impression of a fair breeze blowing ahead of the storm. 

Some grasses, plants and flowers were painted in, and then the birds in the sky, which give a sense of distance and perspective. Mist in the foreground, and ... done!

And if I do say so myself, that's not bad at all. This is about as far as you can push DAZ, landscape wise; and I'll be honest, I still struggle with Bryce 7 Pro. It's hit and miss, even now. Here is my best to date:


...and that also is pretty neat. But just stop, take a deep breath, and have a look at this:


Uh huh. Vue Esprit, plus the plugin modules for Botanics, painting in populations of plants and so on, atmospherics, and ... hmmm. Embrace the concept.
