Hi! So i wanted to do some walkthroughs in UE but when i move with my player i can’t get through the ceiling, it’s imported with datasmith from ArchiCAD. In ArchiCAD there’s literally nothing in this place so i don’t know why UE is blocking the passage. Images attached to be more clear
Open the mesh and in collision settings make it to use “Complex as Simple”
Yep was going to say the same, if you don’t import your asset with a collision mesh and use the auto-generated UE4 one, the generated simple collision mesh is usually a very simple outline that ignores any holes, windows, large indents, etc…
Thank You guys, it worked, but now another problem occured, i can’t save those assets.
It’s possible that the mesh is too complex for “complex” collision? Or it’s not a closed manifold or something.
An alternative is to open up the static mesh in the unreal editor, and remove the existing collision geometry, and then add a number of collision boxes and move them around to provide a floor to walk on, but an opening in the center.
Or you can just remove the collision entirely, and then add invisible collision volumes in the level to match. That might be the simplest.
A third option to go along with jwatte’s suggestions. Remove all collision from this mesh, create a new mesh in whatever 3d program you are most comfortable with that’s just simple collision geometry, import that and alight with the existing building, use Complex as Simple collision, and make the geometry invisible or hidden.
