ok so i started...and i cant even get a texture down.
i am in mapping for dummies/basics.
i got to this part....
To add texture to a brush to make it pretty, select the brush (or face of the brush), and then in the window with 'exterior, interior, + tex', expand the tex node, then double click a choice (exterior and interior also have their own choices), such as tex_nature. Then select an image in the resulting list, and it will cover your brush. Ctrl TAB if your window is acting oddly after applying a texture, especially with moving around the view, described below. You need to leave the 'texture application' window and return to a normal window.
now i can select my brush by holding shift down and left clicking, but i dont see any window with exterior, interior, +tex.....where do i find that window, or how do i bring that up?
