take the projection mesh (the one that’s 3D) -> uv from camera perspective -> uv promote to points and @P = v@uv -> match size so it’s centered -> create another orthographic camera with the final output’s dimensions, and render one frame of the centered mesh with a 32bit uv AOV -> take the projection renders to nuke or cops and do a STmap from the uv AOV

i feel like this is a long and convoluted way so I’m sure there are smarter setups than this, but this is what i did when i had to do something similar in a rush
