cwalrus Posted February 11, 2016 Share Posted February 11, 2016 (edited) I can see how to add noise as a displacement on a mantra surface, but how can you add procedural noise as a bump map? The displacement option takes a long time to render... This seems like a simple task - ! and while I'm asking simple questions - how do you remove all unused shaders from a scene? (there's a command for this in Maya) EDIT: found answer to second part - a little button on bottom right of Material Pallette says "Show only unassigned materials" Edited February 11, 2016 by cwalrus Quote Link to comment Share on other sites More sharing options...
Atom Posted February 11, 2016 Share Posted February 11, 2016 You can use the op: prefix for a COP path to reference it in a material filename field. ap_COPs_based_bump.hipnc Quote Link to comment Share on other sites More sharing options...
