Specifically the Rifle from the Silver Military Weapons pack
I’m also using the supergrid floor
I keep messing around with collision trying to stop it from falling through the floor, to no avail.
A little help?
How do you drop the rifle? Skinned meshes don’t generally have collision on their own; you need to add a box collider component to the same actor as the actor that contains the rifle, if you still use a skinned mesh.
If it’s a static mesh, then make sure it has collision defined in the mesh editor.
Generally, though, it’s often the case that games will define two separate meshes for a given prop; one to use when wielded (which could be skinned and animated) and one to use when dropped (which would be a “dumb” static mesh.) The actor that “owns” the “idea of the object” would enable/disable the appropriate components based on how it’s being used.
Make the floor static.
