Not really sure if this is a Corona or MAX issue, never had it happen before using 8 or MAX 2017.
It seems that while adjusting UVW mapping with interactive running, at least with a bercontile map material, holding and pulling the arrows on the move transform type box causes the crash. Also, if you click the arrow a few times instead of dragging it, the crash happens. Clicking the arrows slowly is ok...but not very productive as it takes much longer. Had about 5 crashes in the span of 10 minutes doing this.
I do this while adjusting brick materials so I need the fine intricacy.
Running Corona 8 on MAX 2021 with Windows 10.
Thanks for any help!
