Iray PBR Pro SciFi Shaders MR

At the request of many users, here is my first set of 30 Iray PBR Pro SciFi Shaders.
PBR (Physically Based Rendering) refers to the concept of using realistic
shading/lighting models along with measured surface values to accurately represent real-world materials.
In complement to the PBR shaders and to add more versatility to the set, i added 35 Normal Maps
created with NVIDIA Tools from maps synthesized in Genetica and/or FilterForge.
This set would be complete without a set of Normal depth; T HOT4SHARE.COM
