One thing I wonder about Spine is how I'm going to get collision polygons working when my engine only supports boxes and circles. Spriter is already collisiin box-based but its lack of unified skeleton is what worries me

If you can do arbitrary, non-self-intersecting 4-gons, you're done. If you can only do boxes with orthogonal sides, just enclose vertices of Spine bounds in smallest ortho box/circle.
Yeah, that's what I think I'm gonna do. Though I do wish they just had AABBs and/or circles built in. When I draw the boxes myself they are always lopsided.

Guess it was better to start from the general case, especially since most engines support arbitrary (convex) collision shapes. It's a planned feature though https://github.com/EsotericSoftware/spine-editor/issues/179 …

Yeah, hopefully I can nag them into speeding the process up.
