Thanks for the screenshot.
So merge duplicated appears unchecked for “Packed mode” in my theme, but frames are actually being merged, and this option can’t be unchecked for “Packed mode”.
The problem is that I need the animation packed (textures width and height has a limit on mobile for perfonmance), and I need it doesn’t merge duplicated because Babylon JS has issues at the moment and the animations need to be lineal.
Why forcing merge duplicated on “Packed mode”? No sense in my opinion.
I’ll be using “By rows” mode and “Split tags”. For now that works.
