outdoor

Just looking for some info on outdoor style maps. Something like esf_cell_**** for example. When building a map that size with that many cliff type poly's it hits up the r-speeds, making up a valley would help by adding in hint brushes. But on the map i created, the sky texture is drawn out...

when i downloaded ESF there was just few small maps in it. Can somebody tell me where i can download some bigger and not so boring maps? o_o
