50 Shades of Fabric Shaders for Iray and the ILFS Layered Fabric System is exactly that, a set of 50 original fabric print designs (not scanned or copied) in both standard Iray shader format based around the Iray uber base shader and a mirror set of the exact same designs for the ILFS Layered Fabric System custom shader. 

This gives you both the simplicity of just adding a shader to an object or using the immensely powerful and diverse ILFS fabric system to integrate the same design in the fabric shader onto any of its base components, and then mix it up using the various layers and layer settings in the Layered Fabric system Shader (which you need to own to do this of course!) to produce an infinite and fabulous array of effects, distressed fabrics, faded patterns, patterns overlaid with other patterns, different weaves, knits, nets and base colors, literally making 50 designs into thousands of different possibilities. 

However you decide to proceed with texturing your cloth, using either set of these wonderful shaders will give you dramatic, colorful, and lush results with minimal effort!
