Follyx Posted October 23, 2021 Share Posted October 23, 2021 (edited) a simple attribute vop noise layer: P -> noise -> add with P -> output in P and CD. the whole model becomes green and not black and white Independent wich kind of noise... - never saw that before. no materialpath attribute in it. Any Ideas? Ah: Hou 18.5.596 and GPU drivers are ok. Edited October 23, 2021 by Follyx Quote Link to comment Share on other sites More sharing options...
Fenolis Posted October 26, 2021 Share Posted October 26, 2021 Why would Cd be black and white? Cd is a vector attribute with rgb components. If the components don't have the same value (P is a vector attribute with xyz components, points/prims in different positions in world space will have different values) then each channel in RGB will be different. Cd is typically a normalized attribute with values between 0-1, if channel values are outside that range they crush the values of the other channels. Attached is an image showing how to use a single component of a vector. Quote Link to comment Share on other sites More sharing options...
