jim c Posted May 28, 2012 Share Posted May 28, 2012 In the SSS section there's a tab for creation of the point cloud. However I'm not sure if this is working. When I change it to write Point cloud, it doesn't generate anything at all, no matter where I set the file name. If I try and create a point cloud manually, using the SSS Scatter SOP, then I can get the .pc file generated, but when I use that file in the material I get errors that it's not a valid point cloud. My geometry is a simply Polygon Mesh Sphere, with Polygons as Subd turned on. Is there another step that you need to follow to properly generate the .pc file?

jim c Posted May 28, 2012 Author Share Posted May 28, 2012 INteresting, but when I create a shader from scratch and add the Physical SSS VOP, then it will generate the output file! I have no idea why one is different from the other. Quote Link to comment Share on other sites More sharing options...

I have no idea why one is different from the other. Have you done a full render after setting the sss pc option to write ? I had unwritten sss files when tuning shaders with IPR. The files where not written to disk until I launched a full render. Quote Link to comment Share on other sites More sharing options...
