Weird invisible barrier collision issue

[MxtchaMintz]

I am trying to make it so you can walk straight through this building.

When I try to walk through the doorway, there is a weird invisible barrier, but only on the left side of the doorway.

I modeled the entire building in blender. The floor and the top of the building are separate parts already. Before, there were a lot more weird invisible barriers, but then I changed the collision fidelity to “Precise Convex Decomposition” and now there is only the one on the left side of the doorway.

Try using this tool in the Studio settings menu (Windows default shortcut: Alt+S)

It shows the actual collision mesh of objects, this helps alot when making meshes and unions and the like.

Next time, avoid modeling entire simple buildings in Blender. It’s not going to be worth it.
