rjpieke Posted December 13, 2005 Share Posted December 13, 2005 thx.... howo to turn onn trace displacement in houdini 8 for prman? 23201[/snapback] (I'll give the H7- way ... maybe H8 has a "better" solution) On the object, go to the Render Tab and, in the Pre-Include put down the RIB snippet. I think it's something like: Attribute "trace" "int displacement" [1] Cheers! Quote Link to comment Share on other sites More sharing options...
ykcosmo Posted December 14, 2005 Author Share Posted December 14, 2005 so, in this way, I can insert the RIB right? Quote Link to comment Share on other sites More sharing options...
George Posted January 12, 2006 Share Posted January 12, 2006 Hi ykcosmo, In Houdini versions before 8, the renderman ROP has a "Visibility Trace" parameter that you can put the list of objects for which you want ray tracing. In Houdini 8.0, each object has a set of parameters that control the various rays to which it's visible. There is more detailed info here: http://www.sidefx.com/index.php?option=com...iewtopic&t=5012 Take care, George. Quote Link to comment Share on other sites More sharing options...
