Blurry floor plane when using projector
Hi all! I'm trying to composite a 3d object into a scene and I'm trying to use the floor plane demonstrated in the "How to light 3d models realistically" youtube YouTube so that the object can cast a shadow and have ambient occlusion etc. It works, but the resulting projection is noticeably blurrier than the raw footage - by making each layer visible or hidden I can compare directly and it's not a perception thing.
I'm a new user and probably over-stretching, but I guess that's not uncommon given how great Hitfilm is to use! I did a quick forum search but the only thing that sounded close was this, which looks like it was resolved some time ago. https://fxhome.com/forum/discussion/7615/projector-effect-is-not-working-correctly-being-investigated
Does anyone have any idea what I might be doing wrong? Thanks in advance!
