btw. If I may make a little remark: Yes, it stands in the release notes but it’s only mentioned once, it’s quite far below between a lot of text and if you search for “FBX 2016” you dont even find it, you have to search for “FBX” or “2016”. So, i knew it was in there (after I found it), i just thought it should be posted more prominently. Although if it should be downwards compatible, nothing to worry about but as shown above, there are assets that work perfectly fine with 4.9 and dont work at all for 4.11
