xgen using uv textures maps

Hi,


Using maya 2018 xgen. Not interactive method.


I have several long hair grooms that I would like to map either a single uv texture map or multiple maps up the strands. I would like to be able to sample the exact spot on a uv map.

I've tried several ways of mapping a texture map based on my models uvs and I can't get it to work correctly. What is the simplest way to just pipe a uv'd texture map into the aiStandardHair shader?

I've tried using ramp in the base, file in the base, and both methods in the diffuse section.


I've tried turning off the CurveImplicit UVs in the ramp util and couldn't get it to work.

From what I am seeing it feels like I need to bake my uv'd map into a ptex to get it to work correctly.

New to maya so maybe I am missing a param I just need to turn on under the description?


I found another method online to bake out a ptex map but I don't have access to nuke or any comp software. Plus, there has to be an easier way to simply map a texture on hair.

Any help much appreciated.
