I have downloaded a house mesh and want to make my agents move inside through the door. The house consists of several submeshes that I have added into one blueprint.
The problem is that by default the whole mesh is not navigable. I can set the collision preset to “NoCollision” but the agents will just move through the walls then.
This is the navmesh with collision set to “Block All” on all submeshes of the house:
I assume I would have to alter the collision meshes of the sub meshes somehow, but I am not sure how and if this would be the right way? Take this example of the entry area: The complex collision mesh looks fine, but the simple mesh covers the door area, I assume that is the problem?
How can I fix the simple mesh to allow navigation? I am not a 3d modeler and I would like to avoid working on the mesh in an external software if possible. Or is there another way to make the house navigable that I am not aware of?
Thanks in advance
