Strange scene behavior when material appeared in ME

[Bormax]

Hi
Strange thigs are happening with latest DBs. Please, check the attached video.
Everything is going normally until the moment when any material appeared in the ME (even if it's not assigned to objects), after that any actions with objects looks like the strength of mouse movements were multiplied by 10, and there is no more actions written in "undo" list, no way to undo anything.
I worked with corona-8-3dsmax-daily-2021-12-06 since it was published and didn't have any problems until yesterday. It just happened during the work on regular scene and after that I can't avoid this situation.
It's happening with all DBs after corona-8-3dsmax-daily-2021-09-30, with this one and older ones everything works fine.
It doesn't happen if any other renderer is chosen.

Max 2021.3

PS
Merry Christmas!

Hi, this is peculiar I've had this issue before but not related to Corona in anyway. I can't seem to be able to reproduce this on my side with the exact same steps. Thanks for reporting this we will investigate further.

It happens from time to time for me too, but i struggle to see any connection with Corona. I noticed that it mostly happens after prolonged sessions with 3ds Max, when i open and close many scenes without restarting max itself.

Hi

I have had same strange issue before, but those times I didn't connect it with Corona and simple restart Max helped to get rid off this behavior. But this time it's clearly connected with Corona.

I've just installed Max 2022.3 + corona-8-3dsmax-daily-2021-12-06 and everything was OK until I tried to work with the same scene I was working on before I faced this issue. Unfortunately now I have the same situation with Max 2022 :((

It seems that the starting point of this problem somewhere in that scene. I also suppose, that it might be connected with the planks objects created by Floor generator, but I'm not quite sure. I checked the scene with Prune scene and Sini Forensic, they both said that there are no virus in the scene.

Now I installed Corona 7 hotfix 1 and Max 2021 and 2022 are working fine.

I uploaded this scene to the Dropbox for you to investigate the issue. File name is 01_AH_01-2.zip

Thank you Bormax, I am afraid I am still not able to reproduce the issue in your scene (3dsMax 2022-24.0) but there seems to be some quad setting or a bug with custom quads including the Corona IR extended viewport, that's probably related to the twitching movements, but that's just a guess. I am getting some weird twitching on the axis of objects and viewport refreshing when moving the cursor around, notice my cursor movements and what's happening (non-local axis, non-transform coordinate center, unfortunately  the viewport-glitch refresh is not captured in my gif but it can be seen in your video).

Can you please try and reset your custom quad and see if it it's reproducible?

Hi. Did you you mean quad menus? If so, I reset them, but it didn't change the situation

Also tried different viewports layouts - no result too

Hi sorry I was referring to the viewport-quad configuration.  Preferably with no docked IR present. At any case we will investigate this further, can you please share your current screen resolution and if you are using any non-default windows/layout scaling?

Hi
Happy New Year!

I tried different viewport layouts with no Corona IR docked in them, but didn't get positive result out of it.
Currently I work on 4K monitor with display resolution 3840x2160, text and icons scale set to 150%(recommended).
As I mentioned I have had this issue previously, that times it was with my old monitor with lower resolution.

Hi again and happy new year! Thanks for the provided info, can you please try to reproduce this with your ENU folder renamed? How to (keep your old ENU as backup): https://knowledge.autodesk.com/support/3ds-max/learn-explore/caas/sfdcarticles/sfdcarticles/Resetting-3ds-Max-3ds-Max-Design.html

Hi

Done. Yes, with new ENU folder Max works normally. Does it mean that some of installed scripts/plugins is interacting with Corona this strange way?

[GeorgeK]

Highly likely that's it yes, would it be possible to provide us with a zip of your old ENU, if you can share a detailed list of 3rd party scripts/plugin you have installed? I will try and pin-point the issue.

Done with Private uploader, ENU folder from Max 2022
