I have an engine source code license. What if I take some of the functionality of CaveUT into the game engine?
That’s fine with us, as long as your project continues to reference the CaveUT project in the documentation, credits, and/or source code. Go the bottom of the page http://planetjeff.net/ut/CaveUT.html for details. Technically, It might help you and it might not. It all depends on how you want to use CaveUT. Certainly, there is likely be some functions that work better with a source code modification, but make sure, first, before you start work. You should also be aware that any changes to the source code will have to be redone when the next version of engine comes out. Also, you run the risk of introducing bugs into the engine.
