Opus is not generating thumbnails for obj/fbx files after installing new viewer

Am on windows 11, just installed a viewer for the above mentioned files, the files thumbnails generate fine in Everything and Explorer but opus still uses the text file viewer.

I have restarted multiple times but still using the text viewer, I checked the plugin list in preferences, and the plug doesnt appear to be there, unless its using a name that is not so obvious. The programme I am using to get thumbnails support is fed

Preferences / Viewer / Plugins, Text-File Thumbnails, Configure.

Add the unwanted extensions to the exclusion list there.

We'll also add them to the defaults for future versions.
