I need to use a motion tile with mirrored edges for a transition I'm making, but they arent showing up (first screenshot). Also, an error (screenshot at the very bottom) keeps popping up, even after lowering the output width and height to 200. Any help? The rendering bar is also moving very slowly.
After Effects CC 2017
(sorry for the weird screenshot, but i didnt wanna put my serial number in there)
try to reduce the value of (output width and height)
To what number? I've tried 400 (reccomended by other people), 300, 200, and 100.
So as for tiles not showing up - everything is working as it should. You are changing output not tile size so you are repoeating your layer but you can't see that because your layer is 100% in composition. To see repeated tiles you have to change tile size or optput but also change scale of your layer.
As for error - you probably exceeding pugin pixel limit.
I was receiving this same message when working on a project with motion tile and it was driving me crazy! I read through a multitude of forums and could not find an answer that worked. I then tried lowering the 'preview' resolution to 'Quarter' on a whim and it did the job! Hope this helps.
