Hi there,
On one of our machines we are missing the layer collision manager!
(Project Settings - Physics)
Attached is a screenshot of the defective UI. I’ve tried reinstalling unity with no success, any suggestions?
The layer collision matrix does not show up when the inspector is in debug mode. To switch from debug mode to normal mode right click on the tab (in the top left of your picture, where it normally shows inspector but currently shows debug).
That did it. Thank you very much!
