We have got some strange bug.
Our anamitor often edits attached images in Photoshop while Spine is running. Spine always auto-reloads used images and it's very useful.
Recently we added a few meshes. After we had got correct setup pose and set all meshes the anamitor made some changes in the source images (the size were not changed).
But Spine didn't reload them as usual. Some meshes show old images like no any modifications were made. And some meshes lost images at all. We exported the project and saw that "uvs" and "triangles" arrays of such meshes are empty now!
It's hard to reproduce the bug. You need to edit and remove/restore an attached images like our animator did.
upd:
How to repeat the bug:
- Make some mesh on attachment
- re size attachment (for example make it 1x1 pixel size) - uv coordinates are updated, we see correct attachment in editor
- change picture back - nothing changes, we still see 1x1 picture
upd:
It would be very useful to have ability to freeze uv coordinates of the mesh, to avoid them of updating it's coordinates when attached image changing it's size.
