You could add a Box/Sphere/Capsule in your Blueprint so it collides with the ray-cast. I now recall having this issue a long time ago with a weapon model, I ended up with a copy of the model non-skeletal since it didn’t need any of the skeletal info or animations when laying in the environment.
I’ll see if I can find a way that supports skel mesh collision too, I have not looked into how that is handled.
