Quake3World

Hello, friends! I'm starting my first terrain map (not first map at all). And i get stuck with the Vis optimisation, everything i tried doesn't give any useful result, Q3 draws a LOT more tris than really needed.
Can you, please, help me with caulk/hint/etc.. placement or point some articles to read?

Download map here: http://depositfiles.com/files/2qfv8sgnt
(alphamap, shader, textures included, all in one archive with subdirectories)
There's some already placed structural caulk inside hills, and hints - but i'm not sure it's all right

P.s. i'm using NetRadiant and Q3Map2 that comes with it

I'll just write this here since it's as good as any:

Would you please not bump up 3+year old threads? It's rather annoying. Thanks.

Your map won't open in GtkRadiant 1.5.0, maybe it's a NetRadiant compatibility thing (don't know why, they're similar).

Maybe it's using alternative texture projection?

Anyway, I haven't checked it, but vis on terrains rarely hides anything from view ever. I don't think there's nothing wrong with the map itself. Q3 is just not designed for terrains.

Yes, there is brush primitives (aka alternative texture projection)

"vis on terrains rarely hides anything from view ever. I don't think there's nothing wrong with the map itself. Q3 is just not designed for terrains."
OK, I know. I just asked if there is a "hack" to improve it.

Yes there is, but it is very difficult. First of all you need to understand what the hintbrush do.
