Update 2019.3 wrecks boolean objects

[StudioAIDA]

After the update to 3ds max 2019.3 a boolean object with some poly modifiers and UVW modifiers is wrecked.

How can I go back to 2019.2?

Hi @StudioAIDA

Is it possible to attach that scene here? I'd like to ask the devs to take a look.

Thanks for the quick reply!

I attached the object. Can you confirm the problem?

[StudioAIDA]

It seems the max file hasn't been uploaded.

Here's another try.

If you are using a Windows OS go to the Control Panel > Uninstall Programs - then on the left click "View Installed Updates". You can uninstall the latest Max update there.

Could you tell us what version of Max this originated from? I notice it has the old boolean tool, which was depricated and replaced with the new Carve Boolean library in 2017.

Thanks!

I'm quite sure the model has been built with 3ds max 2016.

It would be nice if new versions of 3ds Max could read old boolean objects correctly and collapse them on import if needed. Otherwise we would have to keep a version of 3ds Max 2016 on a computer and do the collapse operation before merging them into newer versions.
