Explore the creepy depths of the VAULT OF PERIL in this retro early-90s FPS. Can you survive all five levels and defeat Lord Morbidous?
Use a 2D sprite with animation on the side of the 3D shape. At the bottom of the Properties panel for 3D shapes is "Use object image for faces" which is where you assign the 2D sprite or sprites you want to use. The 2D sprite must be in the same layout as the 3D shape it's applied to so put it outside of the camera's range so it's only seen on the 3D shape.
