Resolution and geometry on G8

Hi all,
I was wondering: compared to V4 or G1 the G3 figures have a lot less geometry or resolution in areas like the arms or the ribcage, making it virtualy impossible to create a realistic looking ribcage for them for example... How does that work on G8? Has Daz continued down the road of geometry reduction, or can descent ribcages with visible individual ribs and muscle definition be achieved on G8 figures without having to go into Zbrush and create normal maps and stuff?
Thanks a lot,
Me

While I agree with you, the point is to use heavy subdivision when rendering to get the details to pop. Yes, DAZ has continued down the low res game figure route with G8.
Genesis 8 is roughly the same resolution as Genesis 3.
Well... That's a pitty... I mean, I have a Titan X 12 GB VRAM Gpu installed, and if I set the level of SubD to 2 or 3, I can only render up to thee characters before the scene is sent to CPU for rendering... If you're going to rely on SubD that much, you should find a way to make it more GPU friendly.
As a matter of fact it's really weird... The genesis figure get better with every generation, but the "problem areas" are never solved... In my opinion, ever since V4 and M4, these figures have lacked the necessary realism and resolution in areas like the ribcage, the wists, the feet (esepecially the feet) and facial wrinkles that naturally occur when you frown or smile... These really "ruin" the claim on photorealism in these figures. All of these issues are still there, going strong now for 5 generations... The only one that has been adressed with the arrival of G8 is the facial wrinkles. Let's hope that G9 then fixes these other problems too :)
Kind regards,

I doubt it's the mesh resolution at SubD 3 that's causing your render to be dropped to CPU, more likely the textures.
They should do something about the textures then :)

About halfway down the page is a free script to lower the resolution of the images in your scene so that it might fit on your gpu.

Edit: actually, page three of that thread is probably where you want to look. hphoenix added to the script, so you should probably download those :)
Nice! Thank you for the links! :)
If you've tried out a bunch of different things that use different textures while setting up your image try saving the scene and restarting DS, chances are good it will go back to rendering with your graphics card. I've tested it twice now when it's suddenly switched to CPU for no reason I can figure out and it's worked both times. It's like it's keeping the old unused textures in the GPU memory so it's filling up and switching to CPU even though the GPU has plenty to handle the scene.
Hi,
Thanks for the replies! I did some tests and I can easily render up to seven G3 characters in one render on GPU provided they use SubD 1. If I set that to 2, the render drops to CPU. Yet I use the same textures... So the way I'm looking at this, it is the SubD level that does the thing... Stupid question maybe, but what does SubD do? Does it only increase the geometry or does it also increase the resolution of the texture? If it does the second, is there a way to make it only increase the resolution?
Also I've noticed in individual tests that the difference between SubD 1 and SubD 2 only shows up in certain areas of the figure. Is there a way to set different SubD levels for specific zones of the figure only?
Thanks a lot,

Subd divides the mesh only. It affects fine details (if any) in the model's shape, and is particularly important for HD morphs and, in Iray, with Displacement.
But those sorts of details are generally only important in close ups; if you are pulled back enough to show multiple figures, HD details aren't usually discernible so anything past Subd 1 is probably a waste.
Thanks for the reply! I can see differences in medium range shots at resolutions of 4050 x 3650 pixels, but only in certain areas when switching from SubD 1 to SubD 2.
But SubD does not impact the textures then?
Thanks a lot,

There is no point in going above one level of sub-d if the figure isn't using HD morphs. Every level of sub-d quadruples the polygon count and the new vertices are averaged with the old thus smoothing the mesh and decreasing details.
Only for Displacement in Iray; displacement in Iray moves the mesh vertices based on the map.
So the 'resolution' of a displacement map is going to be effectively bound by how fine the mesh is (and the displacement map itself)
There appears to be a memory leak related to the GPU when rendering (no idea if CPU too). If it isn't a memory leak, it sure "looks like a duck and sounds like a duck". :)
