# Blending and Mapping in After Effects

<span style="white-space: pre-wrap;">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. </span>

There is a workflow for that. It is:

- <span style="white-space: pre-wrap;">Plug the projector into the computer. Set it as an external monitor (not mirrored). Set Rez to native on projector and computer. </span>
- Mac: turn off the menu bar (toggle system setting “displays have separate spaces” and reboot)
- <span style="white-space: pre-wrap;">After Effects: New Comp Viewer on comp that is the same rez as projector raster / default rez. </span>
- <span style="white-space: pre-wrap;">Place that comp viewer on the projector screen. </span>
- <span style="white-space: pre-wrap;">Lock the comp viewer so that whatever precomp you navigate to, it stays locked to the correct comp. </span>
- Make Comp Viewer full quality (not half or quarter)
- <span style="white-space: pre-wrap;">Full screen that shit. </span>
    - Press Command+\\ for full screen
    - Press Shift+/ to make it 100%

Again, some weird guy is posting about this who seems super smart, successful, and handsome. </span>
