Been playing with Vray. I like it. This is an “out of box” render of some strands, no effort on my part to properly light it, which really is a requirement for fine strands/hair etc. Still, not bad, they have a nice hair shader. I’m less interested in character hair than in fine detail fibers as VFX elements, so I’ll have to see what other looks I can coax out.
This amount of strands doesn’t even come close to taxing Softimage, it’s still interactive on my box…but rendering it at 2k took about 20 minutes, without any optimization. I’d guess that with some effort adjusting some settings I could get a better look at about 2x the speed, which isn’t bad, considering this is a GI render.
It’s a bit splotchy and the exposure is meh – chalk that up to me being a Vray noob. Looks like I was a bit too aggressive with the jpeg compression, too… The full render is much cleaner, and of course this is just a beauty pass, no passes or color correction. A decent lighter no doubt could take this to another level. Hey, I’m a VFX guy I hardly ever get to render stuff.
I’d like to get a feel for how much impact more strands will have on render time. I may have to try a “stress test” over the weekend to see what the reasonable limit for a single machine is in terms of numbers of strands I can get into a 2k half float render while still maintaining this look as a minimum quality…
