Hello, I am having issues with something I think should be simple. Can someone please tell me what I am doing wrong in the images below? I am trying to make a basic door frame with proper collision, but I am missing something, thanks.
My Model in Blender
My Collision
Both Models un-hidden and named accordingly (I think)
Import settings
Collision view in editor (shows solid and it is, player cant walk through)
Please advise, thanks.
Make sure you have an actual collision set on the mesh. Just setting the collision on the details window won’t so this.
Double click the mesh in the Content browser and turn on “show collision”
If there isn’t one let UE4 create on. Just use a “simple” box collision (we’ll fix this next as this will cover the hole)
You can use the "convex Hull creation, but I find for doorways this isn’t always the best.
And since this is a low poly wall/doorway, you can use the “Use complex collision as simple” in the drop down menu witch will use the actual geometry of the mesh to be the collision, hole and all.
Hope this helps.

Hi,
I might be wrong, but isn’t the problem is that you are using a concave shape as collision? According to this: https://docs.unrealengine.com/latest/INT/Engine/Content/FBX/StaticMeshes/#collision ,the engine only supports convex shapes as collision, so you would have to divide that box into convex shapes.
Uncheck “One Convex Hull per UCX” on import.
See https://docs.unrealengine.com/latest/INT/Engine/Content/FBX/ImportOptions/
Wow, nice feature, thanks @Mars007 I didn’t know about this, will save quite some time in the future
