VDB / Volume Color

[petermandk]

Is it possible to set up color to smoke/vdb for example blue or red? I was looking around but can not find any topic covering this so my brain can clearly understand how to do it. Attached is my actual setup, I managed to figure out how to create volume in RPR, but no luck with color so far.

With the current version, you have to define a color grid with an appropriate color ramp. This is not really convenient if you just want to make volume single-colored, too much hustle for such an easy task. So I revised bias and gain parameters a bit and now you can accomplish it using them.

Here's your project that I modified a bit: RPR_smoke_color.zip

But you also need the updated plugin. Let me know your platform and houdini version (including python version).

Thank you very much, this works like charm. One strange thing happens with this new version everytime I turn on denoising I get this error and rendering stops. Without denoising everything is fine.
