Problem with merging 3d models

[piotrek.waciega]

Hello,
I have problem with merging 3d models. Few seconds after merging model to my scene, 3ds max frezes on few minutes. I was looking for soutions on the web, but in most case people has problem with note track and animation layers. My problem appeared when I updated my max version from 2020 to 2022.
Problem occurs in more complex scene. Some 3d models, (eaven complex) merging fast, another very long. Every 3d model is saved in clean scene, majority in newest 3ds max ver.

Anyone have similar problem?

I'm assuming you are doing merges of the mesh from another Max file instead of imports, is that correct? This may be more of a workaround than a fix, but what if you take one of those problematic meshes and export it as an FBX or OBJ and then 'Import' one of them? Does it now come in OK?
