3d block problem

[sharp breach]

Hi I'm new here hope y'all can help me. I created a 3d block a statue and when I import it in game it turns invisible

You can only create 3D blocks up to a maximum size of 30 pixels. It seems you have exceeded 30. (Including rotation, it must not exceed 30×30×30.)

Also given how detailed that model is, there's a chance it wouldn't render properly anyway

You should avoid anything complex, especially if you're rotating cubes
