Just began to write my HL1 modelling-tutorial as html document. I've submitted my proposal 2 weeks ago, but got no answer until now.

I also hosted it:
http://manionsen.bplaced.net/The tutorial is about creating models with Valve's Hammer Editor, some texturing and poly-optimizing only.
I haven't finished yet. There much more to discover when modelling with VHE. 3D-skyboxes, Displacement to model conversion, how to add deails to architecture, advanced texturing techniques, lighting theory for models and faking shadows are comig soon.
Keep in mind that I am no native speaker of English. please contact me if you have suggestions for improvement.
