FFD does not overwrite animations though, please send me the project and tell me what version of AnimeEffects you are using.
My sincere apologies for the 2 month late reply. I forgot I had typed about this. It does seem to work now. (Using 1.7 ver) Before when i would use ffd on an element that already have a move key it would mess up the work the move key did. Now it's resolved I tested it. I also had another issues with the image thing. When i put a new image it wouldn't adopt the existing keyframes. I tested it just now and it seems to work. Thanks tho! (Edit: It doesn't adopt FFD)
