Hi!

Is there a way to bake a volume to point cloud during render?

I did it for polygons by pcwrite function and by micropoly mantra with uniform measuring (1 point for 1 primitive).

But if I do this with any volume shader - pcwrite does not work after pbrlighting node (as part of compute lighting node, and I did pbrlighting manually to get Cf): rendering freezes.

I want to get point cloud with Cf color for each voxel.

This is something I've tried in the past but never found a great solution in houdini. It would be great if mantra had an easy solution for baking lighting into a volume or a point cloud.

Resurrecting this thread.

I'm up against the same issue, I've got a nice look using a GI light for a cloud but it's not instantiable and something like 12 indirect volume recursions traced is ridiculous. So I'm wondering if there is a way to bake the lighting into a separate vector field.
