Unreal Engine 4 provides a collision generator for static meshes but there are times when we have to create our own custom collision shapes especially if the mesh has an opening (such as doors or walls with window cutouts). In this section, we will see both options.

USP_MeshName: USP stands for Unreal Sphere and as the name says, it should be in the sphere shape. The number of segments of this sphere does not matter (although somewhere around 6-10 seems to be good) but you...
