Umm, you should pick one of my maps and take the MapInfo.Lua from it as a base. The default blueprint settings suck, and using one of mine will give you a nice basis to make your own adjustments.
The mapinfo from evorts glacier pass v12 would probably be the best, if memory serves.
For that matter, an alternate good practice is to take an existing blueprint map that you love/like, and gut it of content and supplant your own.
In my evo maps I have s lot of great detail textures perfect for green map splatting. Feel free to take whatever you need from any of them... That's what they're there for
