[Bf-funboard] Tangent normal map in GLSL node materials?

[Bartek Moniewski]

Someone know how to use tangent space normal map in node-based
materials in GLSL mode?
I know how to use them in standard GLSL materials but I have no idea
how to set it up in nodal materials. I tried a bit with Vector Math
nodes but I cannot reproduce proper effect.

Is that even possible with nodes?
I think it will be great to have "Normal map" node like in Cycles.
Those are very basic things, especially in realtime rendering.
