I think this is the bad point puuting out all people seeking simple and direct commands to call.
The engine would be lot more popular perhaps if it was as simple as program as some other 3D indie Engines.
The response i think is , the author of the engine is very skilled and implemend all 3D techniques for you in the Low basic level (and some tools indeed like the editors).
But he don't have implemented anything mid level or hihg level, because he never took the place of a programmer needing direct and easy commands.
He is a pure highly skilled 3D programmer , so he don't have the vision of hight level programming !
