I am trying to read a illumination information from a point cloud I have previously generated using custom shader. Basically I am trying to do the same thing as in Renderman. The difference is that I am trying to use Point Cloud VOPs for this and I only need direct illumination read back. The writing seems pretty straight forward since I could generate the point cloud without any problem. However when I am trying to read it I get only back render and I am not entirely sure what is wrong there. I am attaching the example file.
Thanks in advance,
