Minimum Light Level:Why not for "light"-text. like orange002
Good point. You can embed custom files into the bsp. There is an official commandline tool called bspzip, but there are also GUI alternatives. I used to use Pakrat, but I believe it is outdated now. More info here: http://developer.valvesoftware.com/wiki ... placements.
Wow! Thanks a lot! sounds very promising! and my friend or someone won?t notice that its my own material?
If that works, the possibilities are unlimited. I could open the orange002 with photoshop or what and just make color corrections, then rename it and implement it with this tool you just posted me the link?
Yes, but I'd be careful not to break the EULA by copying Valves textures. 
I don?t go and sell them! If I make a custom map with my own textures (some of them copied and altered valve originals) why should that be illegal?
I'm not implying anything is illigal, just that there's a risk. Read it yourself and make your own interpretation, but I'll bet it doesn't allow modifications to their content regardless your intentions. However, my experience is that Valve won't take any legal actions against their modding community, unless there's commerical intention behind.
okay. but if I change a few things, how will it be possible to say the original was copied? i could look up the whole text behind a material and copy it and say it was my idea? what is so genius about a material like orange002 lol^^
bye and thanks a lot for helping me!
