Man, I’ve got everything else worked out in the vid but this, and it’s driving me nuts. It’s in most (but not all) of the scenes with a virtual camera.
I’ll load it up and see if I can find any hidden (shy) layers.
If I “mute” everything except the camera and the comp it’s viewing, it’s still there.
If I “mute” the camera, it’s gone, but I can’t see the scene because it’s at the wrong angle.
If I “mute” the scene comp, it’s gone, but so is the scene.
If I open up the scene comp the scene is there, but the rectangle is not.
I have gone through and made sure there are no elements within the scene comp at the same z value competing.
I’m assuming it must be the camera, but does that sound like it could be something else? I actually just ignored it at first because it seemed more like a guide of some sort… until I saw it in the final render.
edited to add: Most of the vid was made from scratch, but the scenes with the rectangle are from a template I purchased, so discovering anything has meant some digging through the hundreds of comps.
