I got a lot of addons on 2.79, using temporary files like this:
I run Blender 2.79.7 from an E:/ Drive.
I installed Blender 2.79b official to C:/program files//etc…
Maybe folders in that location are conflicting?
Because the Blender 2.79, when it runs, shows an incomplete mesh menu:
I have this problem with that particular menu since 2017. No one has been able to solve it.
So yeah, these are my configs on 2.79.
Blender 2.8 looks like this:
Now you´d think I can just copy/paste beetween 2.79 different window application instances, right? Wrong! Blender 2.79.7 running on the E drive (my daily developer version) cannot copy objects between window instances. So I cannot paste Blender 2.79 object to another window with Blender 2.79 3D view.
