Hello,
Is it possible to set the emissivity of an object based on a variable value?
It looks like emissive texture can be set by importing a texture file. I don’t understand how to generate texture files, and would like to set the emissivity based on simulation results.
Say I have results for a flame from a simulation code. Can I render light emitted from that flame? Say I generate an contour of some combustion radical that gives me the shape of the flame. Just like I can set the opacity of that contour using my temperature array, I would like to set the emissivity based on temperature.
I there any way to do something like that? That would look amazing.
Background image based lighting already makes a big difference on realistic rendering, but results based lighting would be really cool.
Thanks,
Alexandre
