Thanks JulzMighty. I am aware of Ventilators great plug-in. But it works with models not level-geometry. So you have to render or paint your own shadow-maps for it (no problem for me but maybe for the beginners). And still there is no normal-mapping shader for this plugin, just a fixed function effect.

What scKan and other users (including me) are searching for is a modern shader (normal- or parallax-mapping) supporting light-maps. With such a technique we could create realistic looking scenery.

I personally don't care much about levels or models. I would use whatever works. Though I think models are more flexible. So I tend to prefer them over WED-blocks.
But beginners might want to start with WED's level-geometry to use the inbuilt shadow-compiler.
