Hi!
I'm currently working on a shot where I have a Pyro2 sim with fire and smoke.
The comp asked me to give him those passes:
-ZDepth
-UV
-Smoke Pass
-Fire Pass
Now, I tried to export the standard Pyro2 planes (smoke/firepass and masks) but they're really pixelated (and they're practically IDENTICAL in contents even if in the sim they're not). Not a gamma issue, and the volume step size is fairly small for the scene scale. I just find them not usable.
For the UVs, is there a way to export them (maybe abusing Rest?) or to cheat it?
Depth...depth is a problem I think, I did some research and apparently the only convincing way to do it is using Deep Maps which Houdini doesn't support for EXR yet.
Any other ways? Maybe attach a light to the camera and render out a depth map and use that?
Smoke and Fire passes, as I found the builtin ones not useful, so I was thinking of rendering fire and smoke separately and then let the comp put them together? I don't think it's going to work unless I find a way to render each other with the other one acting as a matte?
Note: this is not going to be comped with RGB lighting so that's out of the question, unfortunately.
Any help?
Thanks in advance
