Hi all

Is there anybody know how to attach the sampled geometry info from the guide curves into Fur node ? I mean I want to export the P/N/Tangent e.g. geometry info at each follicle not only the UV, whitehair. Thanks !

On skin geometry calculate a normal attribute and name it somewhat different from N, for example hN.
Then in fur shader pass this attribute to output node. Then add extra image plane N on mantra top. Thats it.

P.S. Don't know why it won't work with N attrib name.
