Thanks, I was experimenting with the projection and had somehow converted it to a 3x3, thanks for pointing out that it is returned originally 4x4! I think that’s why I wanted to get a gut check on the forum, I’m not very strong on using matrices and figuring out projections for visual effects - so I’m trying to port without necessarily understanding all the steps in the port. It’s easy to make something look right independently but to make it work exactly like BJS’s projections will be… an interesting challenge, I’m sure!
Working on it on the side here and there but will post back if I get progress for anyone interested.
