jumper Posted January 25, 2011 Share Posted January 25, 2011 Hi I was interested in learning how to use point clouds in a vop shader and so took a look at the Houdini Exchange -> http://www.sidefx.com/index.php?option=com_wrapper&Itemid=146 "Hip Files From Point Cloud Presentation May 11th 2005" I am getting errors in the render- dark patches and light patches (see images). These patches appear in a different part of the image every time I render it. I guess the original shader I copied is quite old ... so there may be some compatibilty issues ... not sure. I am trying to figure out how to create point based occlusion in vops. If any one could take a look at the hip I would much appreciate it. (the point cloud needs to be generetated first obj->geo1->rop_geometry1) Thanks! s pBasedOcclusion.hip Quote Link to comment Share on other sites More sharing options...
