A simple ruby model originally created for my own project, uploaded here for anyone who might need it.

• Polygons: 32
• Symmetric
• Scale: ~9 cm height (~3,54 inch)
• 4 Textures (Red, Blue, Green, Gold)
• UV-mapped
• Rigged
• Animated (Rotating Animation)
• Formats: FBX (+ Blender File)

To switch the textures, go to the shading and simply connect one of the four texture nodes with the "color" input of the principled BSDF node. The mesh, armature and baked animation are all included in the FBX file. You can simply import it in UE4 or Unity. Feel free to adjust it, if necessary. Created in Blender 3.4.1.

Note: This is a fully functional asset, not a joke.
