Hi, i am looking to creat e some hot burniong Coals...with animated incandescence.

Would you guys have some kind of hint?

I thought about some pre-made shaders...i am not sure about this though...

i just want some thoughts on how to do this one, please.

Thank you very much in advance!

Xavier.

i think have a barbeque and see for yourself, that is if you dont use gas. :)
try an animated procedural, and animate the size and noise values in and out.

yeh thats right. duplicate your colour noise and use it in the incadescence change the colors to a hot coal burning...orangy red.
then animate the values in that so it looks like its burning oxygen, fade the colours in and out a bit. experiment. :)
