My friend modeled a maze in blender and gave me the .fbx file of it. When imported into Unreal 4 it forms an invisible wall around it making it impossible to enter. I’m not sure what to set the collider to so maybe that’s the issue. Please help. Thanks.
Open the model in Static mesh editor and enable collision view. See if any collision volumes are blocking. If they are the try creating custom collision mesh for your mesh from your 3D package and exporting it as described here:
