Scene crashing immediately upon open

[aaouviz]

So, I have quite a big problem.

This isn't necessarily a Corona related issue but I thought I'd consult the brains trust here first...

I have a scene (it's only happening with 1 particular project) which crashes when I open it. BUT it crashes approximately every 6 in 7 times I open it.

I open the file, it loads, before the geometry is visible 3DS max immediately crashes. No error, no warning, nothing. I open it another 4, 5, 6 times and eventually it doesn't crash. I can use the file as usual, although sometimes a render in IR does cause another crash.

Now, I've tried restarts. I've re-imported everything into a fresh scene. The problem persists.

The scene is quite large, but I've split it up into multiple xrefs - the problem remains. Almost all of the materials are converted from ArchiCAD imported files.

I'm not using any forest pack (I did suspect this was a culprit early on). I'm on Max 2021, Windows 10. Corona daily Oct-15 (but have changed the daily build multiple times through this project, and even rolled-back once with no success).

Any ideas? Thanks!

If you happen to use Multitexture map plugin - this one will crash in some situations with Max 2019 and newer. I don't get crashes on newly created maps but older projects will crash when opening the scene or merging objects using that map.

Hmmm, you mean the one from cg-source? https://cg-source.com/MultiTexture

I used this many years ago, but not recently. I guess it could have found its way in there somehow. I'll have a hunt...

I appreciate the reply, thanks mate!

Did you check the scene and xrefs for viruses?

It is using xrefs (as I mentioned), but it was crashing before I started using the xrefs.

And yes, I used SiNi to check for viruses...
