I a modeling some White-tailed eagles, and found that after taking them through Poseray, the file increases in size (27MB), while directly from ZBrush it's 17MB. Both render well in TG, they only look different in preview. I guess it has to do with normals, but I wonder what explains this difference. Anybody any ideas?
Maybe there's an 'Import/Export Tax" ? :o ;) A ten meg hit seems a bit weird.
But seriously, that's shaping up to be a really fine eagle! Are there going to be a range of poses?
Indeed the increased file size is mostly due to poseray adding normals. Another thing
is the triangulation, doubles the polycount. Can result in really large file size increases.
Any face normal has to be written to the file with xyz coordinates, iirc.
So it's not weird, just normal(s). ;)
Yeah, I guessed that, but still, it's good that TG can render them fine even without those normals, that's what strikes me.
@Doug: I needed a white-tailed eagle for one of my commisions, and it's good practise for ZB. The hardest is now to find good enough photo's on the internet to polypaint (spotlight) all sides of an animal. And yes, I made some poses, but all flying normally, no fancy dives or grabbing a deer ;) I might try that later.
Are you using a set of textures that are projected on these so called "parts" of the eagle, Dune? Or did you bake the texture into one image file?
It's one texture file (and one part, actually), painted on in ZBrush, using spotlight. Perfect workflow once you have some good reference photo's. The rest can be painted in with color in ZB (once I find out how to pick a certain color), or later in Photoshop.
Aaah, I see. Well, forget it then...
I thought that it might consist of multiple textures. I have a few objects in my library that have multiple parts and some of them cannot be connected to one texture. Objects like these tend to grow large AND consume your RAM too!
Generally I tend to notice that the more detailed something is, the heavier it gets (compare .jpeg and .png image files for instance) and as I understand Poseray is not a child's play!
