I am currently making this in UE4 Architecture,but it seems that I still have a few difficulties. The place I’m trying to make is this place consisting of a fountain show and large theater. I have already made the FBX mesh in Blender,but it seems that there’s a mess with the collisions that I can’t enter it. When I remove collisions,they act like air and I fall to the world void. Here’s the model that I have made. I have placed a few textures and merged them into one uasset file. Newest Atrium - Google Drive
From the asset it seems all your atrium is in a single mesh? Did you merge it in unreal? is it already a single mesh in blender?
So you cannot generate a simple collision shape that will fit this detailed geometry.
Best solution is to have your atrium geometry a bit separated. at least the floors and walls are independent geometries on which you can put simple collisions.
I think you can also define convex collision shapes in blender and then import them along your fbx in ue to use them as collision for your static mesh, but I am not very familiar with that.
Quick workaround:
you can go in details of your static mesh of your atrium and select “Use complex as simple” for collision complexity
you can also put cubes, hidden in game, that matches your floors, walls and pillars.
