I'm making a class scene, and I've made a simple projector that displays an image on a whiteboard, everything works just fine, but the image has the perspective that is normally cancelled to look squared in real life projectors. So is there a way to cancel out that warping with nodes? I'd prefer not to manually correct the images somewhere else.
If it wasn't clear, I'm trying to scale the top part up horizontally.
This is the node setup is very simple, just an image connected to the emission color with some mapping stuff to remove the pincushion effect.
