There's a master-class or something of that sort about pointclouds on the Houdini Exchange. I believe it comes with several HIP's using various point-based VOP networks. Also, I wouldn't use the SSS Scatter SOP unless you're rendering SSS. You can use the normal scatter SOP followed by a ROP Output driver (in SOPS) to save a .pc file. Any BGEO will work though.

symek Posted November 15, 2009 Share Posted November 15, 2009 O dear, dear, Mantra doesn't support point based occlusion nor color bleeding (at least non of built-in solution). Point clouds can be used to accelerate ray trace gi effects, but from my experience I can tell, default irradiance cache does better job for it.
