Yes you are right.
All objects corridors, there are no collisions.
I have done so deliberately, because that models are too many polygons. , In the shop, in the description of the corridors, I recommend using invisible walls to determine collision.
I think I need to do its own set of low-poly invisible walls for these corridors.
Still, most of the models of these corridors are not joined in GRIDMODE and SNAPMODE. I was not able to achieve full compatibility.
Due to the non-standard sizes are not joined in GRIDMODE.
A SNAPMODE behaves quite strange to them.
I tried a lot of options. And sets them to the common center, and is equal to the corners. Does not help.
We have to be manipulated by hand.
I've been saying that GRIDMODE much needed additional mode a grid size.
Sorry for the inconvenience.
