I have been adding imported obj’s into my scene as usual, everything is fine, until of of a sudden, my viewport camera does not frame them correctly, or some of them it does not frame at all anymore. When I hit the numpad “.” key, the view goes into empty space. Also tried “center view to cursor” under the align menu, with the cursor sitting on the object I want to work on, but the view would not rotate around the cursor as expected. Something went haywire with the viewport cam, any help greatly appreciated.
Your object origin is probably somewhere weird- edit mode, select all, Shift S, cursor to selected, origin to cursor. Then try it again
I tried, but it did not work, but only because I accidently activated view lock to active, no idea when or how, probably hit the wrong shurtcut. After unlocking the view everything is great,
Sorry for the confusion, but I think your workflow here can come in very handy if I ever import some “dirty” obj’s.
