The decals' color is stored in the last color of it's palette, I believe.
You'd be best making your own - I don't know of any custom decal sites.
Is there a game where you can do something that hasnt been written??Nope. Source offers great capability for these sorts of games, though - Vampire: Bloodlines namely. Yes, the game is already written and (mostly) scripted, but you're offered enough flexibility to have a seemingly infinite amount of possiblities and tactics. Multiply that by the (six?) times you can replay the game as a different class of character (each with different dialogue options) and you get the idea.
Half-Life 2 is much simpler to map for in terms of brush work - It's basically all models.Yes, but one can make stunning brushwork and make a really nice map too. Props ain't everything...VALVe hasn't moved over to a full-3D editor as Epic did with UT2k4.
its basicly the "anarchists cookbook" and "Improvised Militay Munitions Handbook" and "Handy Vandels" online in one place.Sweeeeeeet.
Your is boring.Noez, NW rox.
