What about making a new lighting engine from the ground up within the current version of torque engine that blockland is using?
I don't understand why people have started thinking that the engine is something that can just be modifed and changed easily.
Think of Blockland as a house and everything in it. The engine would be like the walls, floor and roof. Sure, you can remove some walls and add in others, but you have to reconstruct other walls to get them to join correctly, and while that wall is being rebuilt, it annoys a lot of people, breaks a lot of things, and leaves the house messy. In the end, its hardly worth it.
