We have been using the default shading for Hair with Shave and a Haircut. It is really slow. How can we speed this up? Also, how do you attache the Vray Hair shader to Shave? Thanks, Steve

I have seen another raytracer (Arnold) crank through hair and wanted to know what I could do to make Vray a bit more competitive with it. If you do not raytrace through the hair, how do you get it to shadow and self shadow. Mental Ray’s hair rendeing is pretty fast as well but I believe they are de…

I have done some extensive speed comparisons between vray and arnold. They are nearly identical in render speed (not hair), but general shading purposes, shadows, glossy reflections, caustics etc. Regarding hair though, I could not get shave and haircut to work with arnold, so I can’t test it but Im…

As we have here. I find the ability to use brute force and light cache and skylight portals for interiors is FAR faster in Vray. Hence the reason we would like to get hair working better. i switched the lights to dmaps and left the environment dome. I tried hair without brute force light cache…

Yes, I understand the point… the V-Ray hair shader would help with hair render times quite a bit, if only it worked with Shave :slight_smile: I’ll bug Joe about it a bit more… Best regards, Vlado

how deeply does the character interact with interior? could you split the scene into two layers, i.e. interior/character. You may benefit from optimizing the lighting for the character quite a bit.

maybe you should give Peregrine Lab’s Yeti a try? it works just great with the VrayHairMtl’s and it all renders quite fast. Easy to setup and use.

That is really a shame to hear. We are subject to the American blockage thanks to Joe Alter. I guess we have to wait to see what Vlado can get Joe to do in getting Vray Hair applied.

Would we be able to use the Vray Hair shader in Softimage if we use something like Melena or Kristinka? Can the Vray Hair shader be applied in Softimage’s version of Hair (which I know is shave & haircut). Sure would love to get out from under Alter.
