stevenong Posted March 27, 2009 Share Posted March 27, 2009 Hi, The op: syntax is accessible within Houdini but not during render time as Mantra doesn't know what is "op:". You have to write the points to disk and specify the path in your shader. Cheers! steven Quote Link to comment Share on other sites More sharing options...
kuaile_yzh Posted March 28, 2009 Author Share Posted March 28, 2009 Thanks!But what method can transfer OP within Houdini? Quote Link to comment Share on other sites More sharing options...
stevenong Posted March 28, 2009 Share Posted March 28, 2009 If the pointcloud setup is a VEX SOP, you use the op: syntax. Another usage is reading images from COPs in a Point SOP using the pic() or tex() functions, for example. Cheers! steven Quote Link to comment Share on other sites More sharing options...
