If I understand correctly, it appears that a Light Sweet in Title Studios require the scene to be set to 2D composite, so I was wondering how would I apply/create a Light Sweep effect in a 3D render scene, since I need to incorporate 3D Render cast shadows. Thanks for any help!
I’m afraid you may have encountered a limitation for which there is no easy solution but leave it with me for a bit and I’ll try to think through it.
First thing that comes to mind is to create a light sweep going over a solid color image and render that out. Then import this as the media asset for the shadow catcher plane.
