I’m looking for a way to create an animated 2d layer (text effects mainly) which faces the camera at all times.
This layer should not interact with the lighting of the scene.
It is a classical case for after Effects - create an overlay layer with all the animation over an existing video file. But the issue is that the video doesn’t exist and I wanted to make the overlay animation while making the 3d scene.
You can always make two scenes - one for the overlay, one for the 3D scene, and put one ontop of the other - either in the VSE or in compositing nodes.
