I need help setting up the collision mesh for a model of a hallway that i've imported

Hi, I’m part of the recent wave of new Unreal developers and am having a little trouble getting on my feet.

I have modeled a small hallway and am trying to set up it’s collision so that I can walk through it. I’d like it to be very basic, it doesn’t even need to include the lamps in the corners. Unreal Editors tutorial system has been super helpful, but I still haven’t figured out how to manually edit the collision within the static mesh editor. I’ve read that I can create my own collision mesh in my 3d program, but I don’t know how to attach it to the hallway model. I’d appreciate it if someone walked me through this. Thanks!

Take a look at this video: :slight_smile:
Now in 4.6/4.7 you are also abel to move the collision in the engine -> select it and use the transform tools

Thanks for linking the video, it was helpful. I created a collision mesh and named it UCX_xx like the video described, but when I imported the fbx my collision mesh wasn’t used, it was still the default box collision mesh. Do you know what I may have done wrong?

  1. make sure that you collision is not one sided
  2. in the import settings you have to disable “use one convex hull…” :slight_smile:

Wait, I just tried putting a cube underneath the floor as the collision model and that totally worked, so does the collision model have to be closed geometry? Would it be better to place individual prisms for each wall and an upside down u-shaped one for the doorway, or should I just extrude the entire rooms geometry and create one unbroken object?

EDIT: Sorry, I didn’t see your response before replying. What rule should I use to enable or disable “use one convex hull…”? This has been a huge help btw.
