there is a bug specially on

there is a bug specially on max2021+ that is removing the bones at some point and the geometry as well. It as them in the structure but is no where to find them in the scene, as for the geometry it chops vertex from it and even on export it has it as chopped mesh.Can you you fix that issue when you have time? Thanks.

v 1.1 not working

Could not get version 1.1 to work. Was excited with it's Scale Motion parameter and slight update of it's UI. But it just did not work for me in Max 2017.

I opened it, selected the first bone, as usual, and when I click Bake progress bar turns red and nothing happens. Is there something wrong with the tool, it's compatibility with max or am I doing something wrong?



Oh, so it only works with bones now!? I can't just select helper objects or something else and apply dynamics to those like before? Why would you do that... It feels like a downgrade to me.
