I used “FPS Weapon Bundle” from Epic Games Shop. And add Ka47_X to character new hand socket.
But when i add second weapon to the back (“Military weapon dark”, Rocket_Launcher), its has different X rotation. So weapon swap(Socket from Back, to socket in Hand) become broken.
I find forum post that say “Use 3d software. rotate weapon mesh, save and import to UE”, but Blender and MeshLab cant read UASSET files. All weapon data from Epic Games Shop is UASSET files.
