Thanks Rick,
That's right for lightmaps, But even with Graphics cards from 5 or 6 Years ago, lightmaps on the level and using shadows for important or nearest things is optimisation and allows to save power to more expensive treatments , like NPC, ennemies, AI etc ...
I have some a questions :
For GUI elements , i seen Cgui is the recommended ? Or do we have other solutions ?
Is it C# supported or destined to be more developped, or is C and C ++ the best ways and best compatibilities (what i think).
Anyway, purchased the engine and 3D Word Editor.
I like a lot the simple programming in this engine, and it has great features for realtime indeed B)
