Tony Ayalew, you must get permission from other authors if you want to use their material in their mods. I am not sure how other communities do things in other games, but I wouldn't want to promote something that contained John-p's work unless John-p gave it his blessings.

Also, john-p's texture packs are enormous. I'd recommend you focus your MOD on the new work you've done, rather than make 95% of the download size be another MOD that's been available for years.

Left aside the sense in this, with the TDS script system you can basically do anything the game allows after any condition the game knows about. So you can delete the whole non-brush architecture plus AIs if Garrett is seen by a guard or you can make anyone run across the map twenty seconds after a random number has been calculated or...whatever. You can change the screen tinting (like in the Cradle) for night vision (although I don't know how he did this) and I believe camera settings are even in the ini files. You can let the bow targeting mode be inherited from 3rd person (although you cannot aim properly I guess), so I guess technically there's no problem.
