Blending and Mapping in After Effects Normally, you’ll use AE to create your pre-blend map and raster - but, if you’re a psychopath, you can bake in your blend / map / distortion in After Effects. There is a workflow for that. It is: Plug the projector into the computer. Set it as an external monitor (not mirrored). Set Rez to native on projector and computer. Mac: turn off the menu bar (toggle system setting “displays have separate spaces” and reboot) After Effects: New Comp Viewer on comp that is the same rez as projector raster / default rez. Place that comp viewer on the projector screen. Lock the comp viewer so that whatever precomp you navigate to, it stays locked to the correct comp. Make Comp Viewer full quality (not half or quarter) Full screen that shit. Press Command+\ for full screen Press Shift+/ to make it 100% Here’s a forum thread about it . Again, some weird guy is posting about this who seems super smart, successful, and handsome.
