I would like to colorize hair strands within the p_hairTK shader. Therefor I plugged a noise map into the “Diffuse Root” and “Diffuse Tip” slots of the shader, but unfortunately it doesn´t seem to take the UV-coordinates of the 3ds max shader into account.
Then I tried to use a “texture lookup” shader with a “texture vector” to control the UV-coordinates. There are different effects with different settings in the “texture vector” shader, but I couldn`t get it to work properly, so that the hairs have the color of the noise map from root to tip. Can anybody give me a clue how or if it is possible to acheive this?
Edit: I´ve tried this with the ornatrix demo and it works. So, it seems to be an issue with the MR shader implementation of the Fur and Hair modifier in 3ds max.
