I’ve mentioned this in the paper cuts thread, but it’s one of my biggest usability gripes with 2.8 right now.
An FBX file (or even glTF I’m guessing) does not care about collections, only hierarchies, so it’s imperative that all quality of life features being designed for collections also apply to hierarchies!
I mean, you just designed one of the larger usability gripes with 3D Studio Max straight into 2.8! In Max, hiding hierarchies also takes multiple clicks, so everyone uses layers instead, and those don’t get exported either, so files end up being very poorly organized often.
