The answer to your question has been posted here:
SkeletonGraphic with multiple atlases
We also replied to you via email, unfortunately the reply only reached your main email adress and not the ones in cc, that was my fault, very sorry about that!
In case you just wanted to keep the question and reply more organized, I will post the answer again below:
After having received your reproduction package I noticed that it is actually related to this forum thread, the description of "the performance of specific spine is corrupts or jitters" was sounding as if there are performance or playback problems like stuttering playback.
Actually the problem with your use of SkeletonGraphic
is as discussed in the referenced forum thread: Unfortunately, multiple atlas pages as used in your skeleton are not yet supported. I understand that perhaps the title of this thread was not precise enough as it lists with multiple atlases
but should be with multiple atlas textures
instead.
Complete explanation from the SkeletonGraphic-Component
documentation:
Important Note: due to limitations of the used Unity CanvasRenderer, SkeletonGraphic is limited to a single texture. This means Skeletons used in UI have to be packed as a single-texture (single-page) atlas, rather than multi-page atlases. See section Advanced - Export for SkeletonGraphic for a possible workarounds to this limitation.
We are sorry that this is not yet supported, but we are currently working on it, so this feature should soon be available:
