About the video:
it looks all nice but they just show very little. If the level really is big, why don´t they show those parts?
Gamestudio gave me a great introduction into gamedevelopement and that is what I really like it for. It is very easy to use in the beginning and gets harder when you want to do more than template stuff but stays always doable.
Lite-C is a really small change for beginners but opens a lot of possibilities for more advanced users and I really like it for that.
Why_Do_I_Die, why do ou say that hobbyists want to create levels and models? I think most users here are wether beginners or people that like to write some nice scripts and sure some others but I think that those are a minority and are already using other engines. I have a lot of fun to create codes to improve the visuals at the moment and I just don´t want to have an engine that already has all that usable through a few sliders

This thread is already off topic now so I´ll go on with that

I would try to create a similar scene with gamestudio if there are people contributing the models for it (I don´t have the money to buy them) and someone who wants to do the leveldesign.
I would do the Lite-C and the shaderpart. If there really is some interest in this, I would start to build up the base and then have the leveldesigner bulding the level and telling me what he needs. I would like to leave the design part completely up to the leveldesigner and it would only get a graphicsdemo for now.
I could also combine shaders with lightmaps using another uv-set but am not able to create the lightmap and such. Other than that I would stick to stencilshadows (maybe with a little blur...).
The whole thing could at least end in some nice shaders for the wiki

and hopefully a level with great graphics.
