Re: Polygon limit
@itsFrank17 's write up here is a good summary: 3D Importer Support for glTF Files [Beta] - #15 by itsFrank17
TL;DR: We’re Looking Into It, but there are also a lot of tricky catch-22s to handle. Going above 20k triangles ends up being a lot to ask out of phones that don’t have native support to divide two numbers, so we have to be careful with the way we handle this issue because we want to continue to support people with lower-end devices. Unfortunately, I’m not part of the team investigating this issue and it goes far deeper than importing, so I can’t give great answers as to time lines other than it’s an extremely well-known issue.
Re: Glueing a model’s props to the model itself
Could you speak more to this issue? What’s the end result you’re looking for?
