Something I would really love to see is Anisotropic when the PBR stuff gets here, both Radial and Linear.  Can be used on all sorts of stuff from knobs to spaceship interiors, and what would be extra cool is a way to control the anisotropic direction using a map, like this :

Very pretty.
That sure would be cool.
I remember when Blender added support for that.

Yes, very pretty, in fact it's my most favourite shader effect next to roughness control

Just curious, seeing as iClone uses Substance materials, and Anisotropic shaders are possible within Substance materials, doesn't that mean we would automatically have this ability when the PBR renderer comes, just as long as we use a Substance shader that uses Anisotropy?

Does the iClone Substance system support all Substance shading features, does anyone know for sure?
I know we can't see all effects right now due to the current renderer, but does it support them all?

If it supports them all, we will probably have Anisotropy when PBR arrives
