Hi guys I want to share with you my shader (there are similar (kind of) shaders in blender market, but mine has few more features, and thus a better results (i can be biased, though since it free (donations are optional, if you want to support the project) you can test it on your own).
All materials on this pics were done with Nexus PBR shader (except for glass); textures were created in Substance Painter.
This PBR shader allows you to export materials from Substance Painter to Cycles with texture maps that were created in SP (the values in PBR shader were tuned to provide maximum similarity to SP values, e.g. roughness 0.5 in SP is equal to roughness 0.5 in PBR shader, metalness 1 in PBR is equal to metalness 1 in SP, etc). You have opportunity to create similar materials in Cycles procedurally with some additional values that should help you in adjusting of material. Some options were included in this node preset to help you with creating custom materials(non-existing in real world, for artistic purposes).
Manual and additional features/tuning will be edit on request. Consider this 0.9 version =)
Any critique/feedback are welcome and help us to develop this project. Cheers. ([email protected])
