yes, this image is only a hard textures working, you can archived this in gamestudio.

about Real time rendering, well when maya also can (hardware render buffer), yes...
but your need a very expensive computer and you not can create a big levels when a lot of textures modeles as in a game engine, and some channel not can render.

the games engines it is a 50% of texture work, 30% of triks and a 20% of technology.

when 6.22 you can use saders, but for now that kind of a beta public.

final in my opinion with better manuals you can create better grafics and more optimizate, there is a lot of difference among what you can really create with gamestudio and what you see in the manuals and tutoriales, make a superb level you need many c-scrip triks, noy only textures skill.

ps: conitec could make a mini contest to create a superb level
