Material of smoke, possible to change? e.g. Self-illumination?

[Alexx31]

Hi there,

how could I apply something different for smoke than only RGB?

Is it possible to assign a real material with all common attributes like self-illumination?
There are many situations, e.g. interstellar fog or a wizardry or electricity, where is is illuminated.

Hey,

Regular materials are never though to function for volumes, e.g. 3ds Max has no concept of a volume material yet, and this is why in Phoenix and the V-Ray VolumeGrid you control the fire and smoke shading using the Volumetric Shading Settings:
https://docs.chaosgroup.com/display/PHX4MAX/Render+Fire
https://docs.chaosgroup.com/display/...er+Smoke+Color
https://docs.chaosgroup.com/display/...+Smoke+Opacity

Particularly self illumination roughly corresponds to the Fire options - the first rollout.

It is possible to use surface materials with Phoenix too - you can convert the simulation to a mesh by switching to the Mesh Render Mode: https://docs.chaosgroup.com/display/...dering-Actions (mind the Surface section options for that mode).

But your question sounds like you need the Fire options

Cheers!

Thanks, so about the fire I have a bit more question in detail

- It needs then the fire channel to be the same like the smoke channel and use instead of smoke only fire?

- Or if they used both, they would need to be simulated identical:
How can I get fire simulate exactly like the smooke does?
Because fire is depending on temperature. (maybe cooling is the same like dissipation, but is that enough to control same behaviour?)

- Or can I convert the smoke channel into a fire channel?

Hey,

You can set the Fire to be based on the Smoke channel. Just go the the Fire options and where it says Based on choose Smoke.

great!
last question: is it maybe possible to render separate renderpasses for each, smoke and fire, to decide later on about how to use it?
