Thank you Graham, I will look into that. So strange that if I don’t move the loops, then they sync perfectly fine. And even if I move them, they still start off syncing perfectly fine, and only become off sync when one of the loops reaches its final location. So so strange.

Hi Patrick, thank you for your help. I haven’t totally figured it out but it does seem to be connected to the very minute differences in how each loop was time remapped. The loops themselves are exactly the same. But when remapped, I followed a best practice suggested on the internet to create a keyframe right before the last keyframe and delete the original last keyframe. That might be where I wasn’t precise enough to cause later problem.


The thing that I find interesting is, if I don’t reposition the loops, then they sync perfectly, so I did not give any thoughts to whether if time remapping had any problem. It is ONLY when they are repositioned and animated to move from one location to another, that they start to go out of sync. It’s even more strange that even in this situation, they start out perfectly in sync, and only when one of the loops reach its final position, that’s when the off-sync starts.

So this phenomena has a direct relationship to keyframed positioning, but I just couldn’t figure out what it is. I tried to move the reposition timing by one frame ahead or behind, and I notice they off-sync at a different rate. Once I got them to sync by tweaking the repositioned keyframe timing initially, but once another loop reached another relocation, everything got off-sync again, and if I tweak the repositioned keyframe of the second loop, the sync that I got for the previous duration breaks away immediately. So I can never fix it this way.

I haven’t gotten a chance to continue to work on it yet, but I will see if remapping each loop carefully with solve this mysterious issue. Thank you for your suggestion.

Hi Ronald,

Yes, I tried Minimax again on just one of the layers, and on all of the layers, and turning up the radius. It seems like somehow my problem has nothing to do with the alpha channel. I’m still trying to figure out why.

Thank you for the 2d Null layer suggestion! Yes I did notice slight slower rendering with layer style. Wow so many choices and great suggestions. Thank you!

Hi Roei,

Thank you for the great tip! Layer style is indeed more elegant and is easier to copy/paste/delete too. I noticed that it seems to render just a little bit slower probably because my computer is a bit old. I’m so happy to be learning so many tips. Thank you!

Thank you Steve!

This WORKED! I have a ton of 3d layers and I put an adjustment layer on top of each like you said. And the seam is gone! Thank you! Now I don’t have to rework my workflow 🙂

Thank you Steve and Ronald,

This forum is so supportive! Somehow shifting the z-index and the minimax effect still won’t work in my case. I found that the problem will go away if I make the bottom layers back to 2d and only keep one top layer as 3d. This solves my issue. I will just have to change my work flow.

Thank you! I learned quite a bit from this thread 🙂

Thank you Roei,

Unfortunately the 1px expansion didn’t work either. I believe it’s because I have 3d layers stacked on top of each other because when I remove all the 3d layers underneath, there is no seam during flipping animation (the background color does not show through).
