Using fire as matte
I have a nice map done in 3d that i need to set fire to in order to illustrate the spreading of a disease (sort of). The fire needs to start off as a small point and spread into a wider and wider circle, eating away at the map. I thought I could set fire to a white piece of paper, with a black background, and use that footage as a luma matte for the 3d map but the fire spreads too much light into unwanted areas for this to work. Has anyone hade experience with something like this?

Hi,
Adding to what Dave said you could use the following old project to give you an idea for the base.
