I’ve made a model of a hole in a wall for my csgo map in blender, however I can’t get the collision mesh to work right. I used knife tool to carve the hole in the middle and then extruded the rest of the face to make it seem like a hole in a wall.
Here’s the collision mesh as it appears in hammer:
Here’s what the model looks like in blender:
The dots I’ve circled seem to be what is making the collision all borked up. It’s as if the face is still there, although it isn’t. How do I get rid of this so that a player can crouch through this hole instead of being blocked by an invisible face?
