Last Version of Aseprite.
I have tried and replicated this error:
- Make in 1 layer a doodle.
- Make a layer 2.
- In that layer draw something that does not overlap with the layer 1.
- Create frames.
- Create an animation on layer 2, no part of what you draw must overlap with layer 1 in any frame.
- Give it opacity lower than 130 to layer 2, where the animation happens.
- Export is as an animated gif.
Like this:
The transparent animated part won’t appear in the result file, it will only appear if it’s higher than 130 AND it won’t be transparent.
When i exported it the result was just a black sphere, no transparent red part.
