Hi guys,

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,
Dawid

to read it back you can just use pcfilter, it doesn't require to be in while loop as you have it now
just plain pcopen-pcfilter-color
but important part, as a channel in pcfilter put just Cd, instead of yours Cd:color, since as you can see when you open your pcloud as points the name is just Cd
then it should work
