I made a fire simulation in Blender. Then I rendered it as a png sequence with transparent background. Now I want to composite this fire into some real footage (the camera movement is already matched). But I can't find out how I can make the fire shine a glow onto my actor in the footage. I am using Davinci Resolve, and have already tried the Light rays effect. But my problem is that I can only give it one colour and I can't use the fire footage as the colour source.
I know that this is the Blendr site but I could find a better place to ask my question. If it is unappropriated over here please point that out.
