hair and fur mod - what coords to map along lenth of hair in mr prim mode?

[joconnell]

Hi Folks,

I'm doing a few furry bits at the minute with the max hair and fur mod and I wanted to use a geometry mode of rendering to use vray shaders and get passes out for the compositors. MR prim is really handy since it gives you the option of a separate shader for the hair and fur rather than the source object, but it seems to lose mapping coordinates along the length of the hair. Geometry mode keeps mapping options but you lose the option of a separate shader on the hair. I think I've tried every possibility of uv / vw / wu and rotation about the u,v and w axis in the mapping coordinates but nothing seems to behave. Has anyone gotten this working or is it a known issue?

Cheers,

John

Hm, we use the coordinates as they are passed from the 3ds Max hair&fur engine and apparently it does not set the W coordinate. Will make a note to do this for the next update.

You're a star. The vray fur modifier itself nearly did exactly what was needed, there was just a few bits of styling that was very difficult to do. The guide spline idea in hair and fur is great, is there any chance something like this would ever be possibly in vray fur?

Well, no, because it's quite complicated, and then you'd want dynamics, and point caches and, and... Nevertheless there may be a few surprises in the next service pack

That's quite true - I suppose it's just all on the manufacturers of the hair plugins giving proper support for mr prim and feeding everything through that. Much appreciated!
