494 075 tris 247 183 vertices 16k: color, normal. occlusion. 8k: roughness, metallic.
80 000 tris 40 032 vertices 16k: color, normal. occlusion. 8k: roughness, metallic.
5 000 tris 2 467 vertices 16k: color, normal. occlusion. 8k: roughness, metallic.
Normal and Occlusion maps are baked from the ultra high definition model ( > 70 M tris) use them for extra detail and sharpness.
