Repro steps:
No hits on the term “Void Autodesk.Max.IAnimatable.GetClassName(System.String ByRef)” I removed a 600 frame skinned mesh animation and a two frame switch animation from the Babylon Animations Groups and then I deleted all key frames from both animations, finally I deleted both meshes and the previously animated nodes from the skinned mesh, despite changes the error remains.
I’ve also imported the Max file into a new scene, re declared the animations, same result.
This is a cockpit model I had previously used in 2020 with no issue and I did not change it, except to open it in 3ds Max 2024 and accept the upgrade changes. Other models from 2020 have not had problems.
