I'm not sure if you used Module3D by Clonetrooper1019 or by TheNexusAvenger before. If you did, you would know that the 3D object cannot overlap a GUI Object.
I have tried this before. I set the transparency to the frame the object was attached at to 0.5, but it shows it is not overlapping.
Here's an example of what I mean: GIF
I would like to know how to make the object overlap, if it is at all possible.
