How to emit fire from texture? How to light objects with fire?

Adding fuel and temperature from a texture is easy, but you can't use the default sourcing method.

Have a look at this simple example : pyro_from_texture.hip

For lighting, I would use pointclouds created from a lowres render using the pcwrite function.

hope that helps :)

Thanks for all the replies guys! Especially you Bunker, for the example file.

Bunker, after getting the pointclouds, what should I do with it? Are there any existing shaders that can read in the pointcloud to light up the scene, or do I have to dig into VOPs...?

You need to build your shader in VOPs or VEX.
