3D Logo doesn't turn around center but some anchor on the left

[jwk]

Hey, I try to implement a 3D logo. Unfortunately, the 3d logo doesn't turn around center but around some anchor on the left side. The 3D is correct and shows up, but if I move the cursor it moves outside the viewport. Can anybody help? FYI: I'm using the 3D file in a huge scale – fullscreen.

hey there!

i think it has to do with the position of some rotation axis in the 3d file itself.
im no expert at this but i think you somehow need to change the 3d file to have a different rotation axis
