Generation of maps to fix normal map aliasing.

[Natural_Born_Noob]

Proposing the generation of a helper map that could fix aliasing both in app and in the final engine of destination.

At this address http://blog.selfshadow.com/2011/07/22/specular-showdown/ is shown an interesting technique for fix normal map aliasing.In the blog there are examples of texture based techniques (es Toksvig map) generating a special glossiness map from the normal map(it may possibly be adapted to roughtness.

This map could be generated for glossiness and roughtness in substance painterand placed on a layer that modulates against the roughtness/gloss layerstack.

It then may be updated manually (with a button in the layer option or at export time) or automatically(by user choice) when height values are applied to the normalmap to cope with changes.

All the system could be made totally optional and turnable off at any time.
