I have been now looking trough many topics to find the answer but cant seem to find anything that could help me solve this problem...
So yeah, i tried newly out the nice examples from this topic
It seems the main thing is to shoose the right path of the model in the properties after inserting the 3D object.
Now heres the problem, I make a new 3D object to recreate the same object with the visible 3D model in construct.
I put the same path for the model, but it wont show up...
Is this a bug, or do I have to download a missing addon to make it work?
