Soviet russian faceted glass Low-poly 3D model

I used Eevee render for most of preview pictures but 10th and 11th was made in Cycles. This model contains Base Color, AO, Roughness and Opacity maps for Eevee real-time render but if you want it for Cycles you will have to adjust Opacity map (i used substraction math node for these Cycles renders). If you want more realistic results, i included another .blend file with trasmissive material so you will not spend any moment to adjust something. Very first picture shows how the model looks in Cycles with trasmissive material. There is also .spp file if you wish to change textures.
