When i converted irradiance cache file to pointcloud .geo file and loaded it into houdini i saw 11 different attributes stored in each point. This is list of that attributes: N E R A D
pGradR pGradG pGradB rGradR rGradG rGradB.
What do they mean?
I think E is value of occlusion, N is surface normal, but what does mean the rest?
