ikarus Posted January 10, 2011 Share Posted January 10, 2011 I have a setup where a grid has UV coordinates based on camera projection, then based on the UV values, i delete the outside points, a basic camera-cull, but for some reason the area behind the camera is getting the same positive values as whats in front of the camera, and im not sure how to clean it up as the camera is on a moving track, any suggestions?

anim Posted January 10, 2011 Share Posted January 10, 2011 here is a file that doesn't require uvproject it's all done in single VOP SOP with to NDC node i also converted group to primitives before deleting to be sure no polygon inside camera is deleted, because that may be the case if deleting outside point belonging to inside polygon uvprojectprob_fix.hip Quote Link to comment Share on other sites More sharing options...
