WARNING: surface at () () too large for desired samplesize/lightmapsize/lightmap

[BooT]

I've been building a map lately, and every time i do the build, the "Warning......" pops up.
So, i look it up, and apparently its harmless. But, as my map gets bigger, more and more of the "Warning...." pop up.
I look it up again just to be sure. It says that when this happens, my shadows are blurring or something.
"WARNING: surface at ( -1728    -64    256) ( -1600     64    256) too large for desired samplesize/lightmapsize/lightmapscale combination, increased samplesize from 16 to 41"
BUT! It says in the example that the increase is only from 16 to 18. Mine is from 16 to 41!
I try doing build again as i get further into the map, and finally there are so many of these warnings, that is just says
"WARNING:.........
WARNING:......
Connection closed."
When I looked the warnings up, one solution was to cut up big brushes, so i try that. But, I do that and it doesn't change anything. The same warnings and connection closing. I remember that in the beginning that i used some really strong lights, and thought maybe it might effect things. I delete it, and its the same result as before!

I start to get suspicious. Something was seriously messed up here. So then, I separate the Brushes and Entities into two different .map's. I put 2 spawns and a Player_intermission in the brushes.map, and then try building. There were no lights, and yet the warnings popped up and the connection closed.

If anyone could help me, i would be extremely grateful!
P.S. I also have a problem with "Doom3LightRadius: failed to parse default light radius", which is also very frustrating, and yes i did the thing with the preferences.
P.S.2 is the build thing also known as compiling? or compiling making the map into a .pk3?

I just tried doing without lights and without lights and vis, and those work, but none other ones work.

Yes, the warnings mean that there are too large surfaces somewhere, so samplesize is increased, which means blurrier shadows. You can post your .map if you want others to take a look at it.
The Doom3LightRadius shouldn't be a problem, you can ignore that.
Compiling .map to .bsp = building the map.

my .map is 3.3mb.... lol wont fit should i just ctrl+copy?

Zip it then upload it somewhere. It's ASCII text so it'll compress to like 1/10th of its original size easily with max compression.

Actually, i tried testing again and i realized that i only had a alien_intermission. When i put in the player and human intermission, the connection closed, but i could test the map with all the builds. So i guess i can live with blurry shadows.

BUT! Because of the "Doom3LightRadius: failed to parse default light radius" thing, im having extreme difficulty with lights.
I want to make weak light with a strong radius, instead of a billion only weak ones. And the thing is, i don't think the was from the very beginning, but just started a few weeks ago, FYI.

Thanks for all the help with the warnings, but i dont need help with those if they don't really hamper my mapping.
