I got help from spyker on the sky.
And the bushes are gone for good! The only undergrowth i have right now are small tiny cute rocks.

They rock btw.
I just want to say, that i reverted back to an older version of my map due to massive amounts of NIIOOM! Crashes. But that was a month ago if not more, and i am about 50 % done with my map.
The things i have to do.
Is adding rocks and stuff on the north side of the map, this is about half way done.
Then adding lots of small buildings fields and stuff for the map in general, and fixing up the villages.
Finishing the Old russian outpost.
And adding wreckage of all the wars that have been fought on that map.
After those things are done, its lightmap, and then just edit my map, based on critique.
So, those pics you see up there, just think of them as how the "feeling" of the map will be, not as to how the... Errrr map looks like at this moment.
And, i really cant remember what lightmapping duddeli do Spyker used, i remember liking it alot, but then i couldnt remember what he used.
