Right click on the texture and choose convert to texture object

That conversation make no sense at all.
If that is not an bug:
Do “T2d” meaning a Vector 2d? Where can i get that kind of background information?
What is the difference of the Name: “Textur Object” and “TextureObject (T2d)”, please?

Ok, that’s stupid. I figured it out.

This Button “Mobile Stats” do that kind of error. No clue why that Button is there, witout any project settings for mobile.
