This is going to be a half-assed bug report because I don't have much info to share on it, and I'm wayyyyyy too busy to try and de-bug at the moment, but I'm interested if anyone else is experiencing any similar issues?
Ever since upgrading to Corona 10:
I'm getting constant crashes when using slate material editor. It seems to happen when loading the preview textures/bitmaps/materials (I'm not sure) of legacy materials (but possibly also PBR mats too).
I will load up slate, select an object to retrieve its material, it will begin loading (rendering) the textures etc and quickly crash. I can't predict when this happens, but it's happening often. With some materials, and not others. Sometimes clearing the slate material editor helps, sometimes not. Sometimes it happens on a fresh scene, sometimes old. Sometimes happens 2 mins after loading file, sometimes 2 hours after loading 3ds max file.
I get the usual max error asking if I'd like to save a backup.
My only hunch is that out-of-core textures is causing this. (I had major issues with this back in C9 dailies). I say this as I see the material preview loading and get buggy when the crash happens, in a very similar way to how the out-of-core bug happened to me previously.
Is anyone else experencing similar issues with material preview loading causing crashes?
and
Is there any way to disable out-of-core textures (I don't want this feature anyway).
(apologies for not sharing bug report/scene - will try to do this asap).
Thanks!

Yes, there is. Look for the checkbox in render setup>performance>performance settings.

Excellent! Thank you. Will see if this changes anything and try to provide proper feedback :)

I have disabled OOCT right away and i have no Corona related crashes, but i'm on 9HF1, so likely that's unrelated to your issue.

Hey,
This could be to do with the new material preview caching..
Which exact build are you using? If it's not the latest one, please first try updating to 2023-01-31 as we fixed a bunch of preview cache bugs there
If it still happens you can try to disable the preview caching here: render setup -> system -> system settings -> material editor -> enable caching
Lastly, can you send over the scene or problematic materials and we can work on fixing this asap :)
Cheers,
Rowan

Hi, I'm on 2023-01-02.
Will use latest daily and let you know how I go.
If the problem persists (with out-of-core disabled) I'll send thru a scene.
If it doesn't persists after a few days I'll try out-of-core again and see where we're at.
Thanks for the feedback and info.

Hi,
Okay thanks! I'll keep an eye on this then :)

Just a heads up. This issue is persisting, even with latest daily (April 5). Max 2023.
I'll do more investigations but it's happening in all scenes when I load a multi-material in SML.
No idea if out-of-core is enabled or not at the moment... will get back to you.
Very annoying problem.

Hey,
Can you send over one of these scenes, and if possible a minidump, please?
Cheers!
