Doesn’t also Collada have other features that most other, modern formats do not? Maybe it’s outdated as hell, but it works great. Speaking of the topic, I brought it up myself in a separate thread here, just didn’t suggest any alternatives, not knowing which would be better: What will happen to Workshop player models when Blender inevitably drops Collada support? . In that thread, it was also brought up by the only person who responded there, that using older Blender versions is also always an option too.
