Matcap material in Cycles How to recreate this selected matcap material in Cycles? It's most glossy in the center and has this special coat.
To recreate this matcap try to use some Layer Weight nodes. Experiment with the Color Ramp node's modes and slider's placement also.


Here's my nodes setup. I basically added two Emission shaders- one with the white color and the other one with black color. Then used the Layer Weight (Facing) (with different Blend values) and Color Ramp (with different modes- Constant for the bright rim and B-Spline for the blurry interior of the sphere ) nodes.


Here's the test I've done using my low poly gerbil model. The matcap and the render result look almost the same. It is a matter of tweaking some things. If you want to play with the nodes to make the rendered matcap material look perfect here's the .blend:
