I think you guys need to walk through the code and instructions you've posted for UE4 because I don't see how it works out of the box with instructions as written.
- Install Spine Pro 4.1.19
- Load any example.
- Export: .skel
- Build SpinePlugin 4.1 w/ spine-cpp 4.1
- Import skel: crash. (null deref in updateRegion)
okay so let's try with json...
- Export: .json
- Import: it works...but...
- Add the renderer & skeleton to an entity: you get nothing. sometimes a single part of the model in some examples.
For such expensive software I do expect more of a plug & play experience to get basic examples working and no crashes. When I search I find few people actually using UE4 and they also report this crash for a couple months now, so +shrug+ ?
