Sbsar
Sbsar refers to a file format commonly used in 3D texturing and rendering. It stands for Substance Painter Archive, though it is now more broadly associated with the Substance 3D ecosystem developed by Adobe. These files are designed to store PBR (Physically Based Rendering) material information, including textures, shader parameters, and other properties necessary to define the appearance of a 3D surface.
The sbsar format allows artists to create complex materials in software like Substance Painter or Substance
