Question: How is the diamond craftsmanship for luggage and bags made

Answer： A diamond model can be made with an external modeling software and imported. When rendering, change the rendering type to "Gem"

P.S. In actual operation, because each model has many faces and when the number of model faces is large, the computer operation is prone to lagging. Therefore, it is not guaranteed to achieve an ideal effect.
