The compressed package includes multiple file formats:
-3dsmax 2018
-3dsmax2015
-fbx2018
-obj
Including various textures:
1.PBR MR
AO+BaseColor+Metallic+Roughness+Normal(DirectX)
2.PBR SG
Diffuse+Specular+Glossiness+Normal(DirectX)
3.V-ray maps
Diffuse+Reflection+Glossiness+ior+Normal(DirectX)
The fbx file specifies the v-ray mtl for 3dsmax before exporting, so importing to other software or other renderers requires reassigning the material. The material naming is very standard, making it easy to assign the material in the later stage.
