I am new to this forum and thought maybe someone would be able to help me. I would consider myself to be an intermediate user of After Effects but I have not worked much with masks and when I have the concept has always confused me.
I have a locked down shot of a log cabin and I want to be able to mask the windows and then composite a layer of fire behind it so that it looks like the fire is burning inside the cabin. What is the best way to go about this? I just can't seem to get the layers set up properly to achieve my goal. Thanks in advance for your help.
