bretik Posted June 28, 2018 Share Posted June 28, 2018 Hi, I made Hairs in Houdini 16.0.557, I made a Hair Standard (Arnold) material where I used Ramp in "V" for color along hair strand. It works in Htoa 2.0.0 (Arnold 5.0.0.1) , unfortunately I have to render this on farm with Htoa 2.0.1 (Arnold 5.0.0.2) and this is not working anymore, it looks like it taking the source geo for hair and colouring whole hairs. (I have kind of strips on these hair strands) - not any more on Htoa 2.0.1 Any Help? Or some workaround? Thanks. B Quote Link to comment Share on other sites More sharing options...
bretik Posted June 28, 2018 Author Share Posted June 28, 2018 Solved: From Arnold 5, the UVs on hair are the skin UVs. You can use the barycentric coordinates to get the per stand UVs, in your case that would be "bv" from the state_float shader. In Arnold Hair shader ad "State Float" choose "bv" plug StateFloat to a ramp (texture) input and change "Pattern" on Ramp to Custom. 1 Quote Link to comment Share on other sites More sharing options...
