Color spread – This parameter changes how rapidly the convex/concave colors replace the flat color as curvature increases. Increasing this value means the result has more of the convex/concave colors mixed in. Max samples – This parameter defines how many samples are used. A higher value renders slower but produces clean results faster. Even low values eventually converge to a clean image. Ray directionality – This parameter defines how strong the tested rays are concentrated around the normal. With a low value, all directions are considered equally. Increasing the value causes the shader to be more dependent on whether the direction directly above the surface is occluded or not. Max distance – This parameter determines the radius that the curvature traces. This can be used to match the curvature between big and small objects. Distance texture – This allows you to use a texture map or shader for the transition between the calculated curvature and flat surface. |
