I was trying to do this a while ago. When Octane 3 arrived and had native support for Particles I was excited.
My first attempt using krakatoa prt loader failed:
viewtopic.php?f=81&t=54175
I cannot test this anymore since I do not have access to krakatoa mx anymore at the moment. maybe someone can try this again?
Well, new attempt:
Now I got a point cloud witch RGB Values.
I thought maybe I could somehow get a volume out of it. I tried houdini's new lidar loader and managed to write a vdb file, but the vdb does not contain voxels, only vdb points which are not recognized by octane volume object.
I read about the phoenix prt reader:
https://docs.chaosgroup.com/display/PHX ... +PRTReader
I was able to export PRT files out of houdini from a pyro sim for testing, but how to get it into octane pipeline? Where to apply an OctaneParticle modifier? I can link the PRT Reader it with a PHXFoam, but I cannot apply the OctaneParticleMod to the Particle shader.
Any way, all I am trying to do is basically transform my point cloud into a particle system which Octane can render with geometry that behaves as movable proxy (like a little sphere) which gets its color from the RGB of each point. Sound simple? Is not
Any suggestions? I guess in two years Point Clouds will be natively supported by octane without going the extra long way I am trying to go.
Cheers

edit: here a screenshot straight out of recap to show what quality the point cloud is:
