Well, i'm new and i was wandering how do i combine two map types? ex:jungle in space
Well, you gotta go into modding to do that. It isn't possible to combine two different tilesets into regular Starcraft.
I suggest (since i see your not that experienced in map-making), dont go into modding. Its really actually hard, so you'll be loaded with questions to ask.
So the answer is...you cant mix two map terrains together
ADD:
Wait, if you mean the pitch black tile-Null- then yes, you can put "space"(Null is what its called) on jungle. You need Starforge of Scmdraft. Both can be downloaded in the Downloads database under mapping.

I sometimes get a glitch in square tiling, when i do the mac glitch to make 2x1 tiles. sometimes it has a black"null" area in jungle usually. kinda weird O.o
