The Chaos Group announced an update to V-Ray 2.0 for Maya, offering new hair and fur capabilities, V-Ray RT GPU enhancements, and tighter Maya integration. The update is free for V-Ray 2.0 for Maya users.

New Hair and Fur Capabilities
A new VRayHairMtl shader to render hair and fur with unprecedented control, quality, and speed
Extra attributes to apply materials to Maya’s native hair

V-Ray RT GPU Enhancements
V-Ray RT GPU now supports texture-mapped rectangle and mesh lights, simple light portals, and the VRayBlendMtl

Hi Buexe and all,
Chaos Group will soon post some video tutorials for the new capabilities. Will keep you updated!

+1 for this, look forward to seeing this. Would like to see how it handles transparency and also how it works with Shave and a Haircut,

did some tests with the beta, and it looks amaazzzinnggg. I had some gi flickering, and it wasnt amazingly fast, but it was an early beta. Hopfully next project i can hopefully do the hair in vray instead of 3delight.

It is pretty awesome, but for my money 3delight still looks better and is faster. I think the reason for this is hair transparency, you sort of get that for free with a rasterizer, whereas Vray you pay dearly. I think Arnold suffers the same problem, although what both renderers are doing is pretty astounding.

I can get hair counts in the millions with GI in Vray and it just works!, you even turn on point based color bleeding in 3delight and its all over.
But 3delight has that beautiful tip transparency and renders pretty quick, I find it is very slow in Maya due to all the RIB generation though (which is not multi threaded). Softimage hair (shave and a haircut) with 3delight seems to be much faster for my money.

Vray is slower than 3delight, no doubt, but if you look at online render farms (like rebus), it can turn around 140 frames at 4hrs each in around 1 hour. This opens up a whole lot of posiblities of raytracing hair with gi. I had to integrate 3delight hair into a vray rendered assets on my last job, its was a total pain.

Pain is the operative word there, I am no fan of 3delight, and I desperately want hair to look great in Vray, which it does for the most part. I think maybe an improvement that could help it look softer is 'tip transparency' at the moment it only seems to have an overall transparency setting.

I am convinced that is what makes the difference in look, in every other way Vray looks better and is really not that much slower. But when you side by side them, 3delight fur looks softer. Of course softer is not always what you are after.

I can tell you it is not painful to do in Softimage as 3delight is so much better integrated, you dont have to tack on all those 3delight attributes. Plus Softimage Hair translate really well into it. (it is shave and a haircut though I guess)

Then you can just switch between Vray/Mental Ray/3delight per Render Pass (renderlayer in Maya)

Hi Guys,

I wrote two new tutorials showing how to use the new v-ray for Maya hair to get realistic hair.

Creating realistic hair with v-ray for Maya part 1 (http://mayazest.blogspot.com/2012/04/creating-realistic-hair-with-v-ray-for.html)

Creating realistic hair with v-ray for Maya part 2 (http://mayazest.blogspot.com/2012/04/creating-realistic-hair-with-v-ray-for_10.html)

I hope you enjoy and start creating amazing hair with v-ray for maya!
