Problems with the generation of NavMeshes in IFC based Imports

[Helevarus]

Hey there,

I am new to Unreal Engine and currently digging into the usage of building information models from AEC industry inside Unreal Engine. I managed to import the IFC file and build up the collision to set up a navmesh. Unfortunately I have problems wit the transition on the mesh from outside to inside of the building and the generation of the mesh on curved stairs and opening in the slab.

I have a civil engineering background and I am currently developing myself in this field therefore I am sorry if I bother you here with a stupid question.

Best regards and thx in advance
Nils

Try placing blocking volume along the stairs as on my skillful illustration

First of all, thx for the feedback. It is working for the first pair of stairs but not in the curved area of the stairs. Also I would rather prefer a solution that is based on the navmesh generation and the IFC-Objects rather then adding blocking volumes as a workaround.

But still thx for your input!

I know, I am demanding much sorry
