Volume Sample at Render Time


Recommended Posts

Is it possible to do a volume lookup at render time using the volumeSampleFromFile and the op: syntax?

The op: syntax needs the nodes inside Houdini. Picture mantra running on a renderfarm node, being fed an .ifd file, no Houdini installed.

So, no.

Ok. I tried as simdata file and a obj, actually written out and it doesn't work. So I guess the better question is can I do a volume look up at render time? It seems volumeSampleFromFile isn't used in rop shop context?

Ok, so it's working except it throws an error 6 in the rop, right at the end. Obviously this is a problem for the farm. I notice yours does too. Do you get this error in the rop node when you render?

I got no errors, except a warning of missing light.
