3D question
I’m trying to use a floor tile mesh to cover an area with, and create a repeating pattern floor.

I cant seem to get the size of the tile (or change it) only its scale property. If i try to get the aabb, for the size it says some ridiculously small numbers.

I’d like help with
1, either how to get the actual size of an instatiated object
2, what other way i could use to cover a floor with tiles (3d, important)
