Create New Map

[moriteza]

Hi guys.
What's the difference between Additive and Subtractive when I want to create a new Map??

Additive is what you use. In fact, I think I just read that they took out subtractive in the new update.

Subtractive makes a level that is assumed to be a giant solid block. You use subtractive brushes to dig out rooms and corridors. It's not very efficient though. You should always use additive.
