Hi! We are currently making the video game. I am implementing the lighting for our particle system. I am satisfied with the simulation and render result, but I need additional data.
We are trying to make kind of PBR rendering for particles so we need :
-Temperature(in Kelvin, to simulate fire using blackbody emission)
-Depth(for ray-marching to calculate light propagation)
-Normals (to simulate the response to direct light)
-Self occlusion and self illumination
-Pure diffuse color of smoke, without any lighting.
I know that at least some of that data is present in phoenix simulations, but I can’t render it, there are no such render elements to output.
I am using 3dsmax 2018 and V-ray as render.
In order to render out render elements with Phoenix you will need to set the Render Mode to Volumetric Geometry. You can find more about it here - Chaos Docs
For the passes where there is no V-Ray one (such as the Temperature or the pure diffuse smoke color) - you can create a Phoenix Grid Texture(find more about it here - Chaos Docs) that samples those channels and plug it into a ExtraTex Render element.
