I was working with the Shave hair in combination with muhHair shader, it was great with the output result and its speed. btw, I was working with maya 6.5 (32 bit).
Now the problem that i encountered is, when using the same method in maya 8 (win 64-bit),the muhHair shader is failed to output anything, and sent the error msg. When I tried to apply the muhHair with a Maya 8 ( win 32-bit) machine, it works without any errors.
So i think it might because of the 32 and 64-bit version of the muhHair shader, i'm new to terms of 32-bit and 64-bit issues and their relations to the mentalray custom shaders, is anyone out there can give provide any suggestion or help?
