I have been "mapping" on and off over the past few months. One thing I could never figure out was how to properly create a building, a building such as the ones in jagd or avalanche. Could someone point me in the direction of a tutorial, or possibly write one? thanks

You've been mapping for a few months, but not used brushes yet?
Because buildings are made with brushes..

the key to making buildings is not wasting any space. when you do that your houses will be 1000x more belivable.

work on creating everything in the house from 16 unit thick sheets. just stick the sheets together however is nessercary, but just use sheets.

Skynyrd, I have a few example maps that you can look at if you want:

Just click my sig, that will take you to the webby.

On the left there are some links under Work In Progress. these are my rmf mapping files.

You will need to download the BSP files as well as they have the required wad files in them. You can download all files from the download section.
