@1: Use Esc to deselect your LOD vertices after manipulating them. If you deselect with V this "lock-up" will happen.

@2: Set your grid to 1 and then you can make brushes as small as 1x1x1.

@3: ctrl + shift + Lclick in 3D view on the face that you want to texture. Only that face will be selected.

@4: Make a brush in the area that you want your rain....give it the textures/common/rain texture, and then right click in 2D view with the brush selected and click func and then rain. In your script: exec global/weather.scr This is a quick explanation.....follow nick17th's link for more info.

@5: You need to compile the map. MBuilder is a useful compile tool....which can be d/l'd from the same link above.......and [url=http://webzoom.freewebs.com/crunch/Radiant%20and%20MBuilder%20Tutorial.zip:cf54f]HERE[/url:cf54f] is a setup tutorial for it.
