Hi All, I've always been interested in modifying maps, but haven't the foggiest where to start with it all. So rather than start from scratch, I have decided to instead modify Valves existing maps. For instance, modifying Dead Center Hotel. Is this what I should be following? Is it simple to de-compile the map, edit it to my liking, and then re-compile? Or is it more difficult than that?
I note also, that it says:
"Releasing reproductions, modifications, or approximations of another's work without permission nor credit is frowned upon and may be considered as a copyright violation."
Should I be too worried about this? If I were to upload to the Steam Workshop, should I just give the generic "this is not mine, all copyrights to Valve etc etc" or something along those lines ?
