Simulating the light of a flickering fire
Hello,
I was wondering if there was a way to simulate the light that is given off of by a fire? Flickering and such. I have created a fire in Maya against a alpha BG and I am incorporating it into some video footage. I would like to add the glow from the fire onto the video.
Any suggestions would be great.
I am using 6.5
Thanks!

Try using the “Wiggler” with the “jagged” pop-up on a matted solids transparency with an “Add” math operator on the layer. Otherwise, just keyframe the opacity and copy-paste the keys as flickery as you can.

I got most of that but what is a “add Math operator”? Sorry I’ve been using AE for a while and just now have really started to concentrate on the more in depth stuff.

Serge has an example up on his site, in response to an earlier thread:

see if that helps…

Bypassing all of the fancy techie mumbo-jumbo, the post from Serge just has you duplicating your flame layer (your maya fire), turn on 3D layer, and create a light which uses that duplicate layer as the projection map. You will probably want to move the layer forward in Z space to get it out of the field of view of your comp as well as to widen the area that the projection hits. (note: in order for your BKG and other layers to receive the projected light, you will need to turn on their 3D switch as well).
It’s a cool idea because it will mimic the exact movement of your fire/flame. Wish it had been my idea.
