Hi,
Just change 3ds Max 2014 to 2021, but it looks like many problems when using 2021.
1. When move or rotate viewport then playing animation, it will stop. That was working when I using 3dsmax 2014.
2. When playing animation then hide others layer, that model will become gray (can't show material), which model already skin. But without skin, materials still work.
3. Sometimes frozen layers or models, which models are turn off "Show Frozen in Gray", but become hiding. It supposed to be visible.
4. In the large scene, sometimes could be auto-hiding many models when objects marge, until doing the switch layers' hiding option. That would show normally.
