Hello.
Found some issue when with the unity UI component. When I'm trying to export animation wich has more than 2 atlases it doesn't look correct, the indexes are messed up, but only in UI component. If I use skeleton animation it looks like it should be. This issue can be "fixed" by exporting spine data with less than 2 atlases, but this leads to using large atlases, wich not the case.
I hope this makes sense.
