I have been notified that not all the original files in the current GOG build are up to date, and after a bit of digging, I could confirm - some files indeed are from the 1.07 version of T2 (first release build of the game), and a few are missing completely. so yeah, lets fix this and throw in some extra tweaks as well just for good measure;
T2_GOG_08jan2018_update (extract to your GOG 1.25 T2 folder, overwrite. will reset any cam_ext.cfg tweaks)
-squirrel script now in the root, as people apparently want to run FMs without using TafferPatcher
-updated all original scripts and other files to their latest (1.18) version
-readded a few missing original (1.18) files
-enabled smooth texture edges on all bloodsplats and small plants
-enabled smooth texture edges on all large plants and backgrounds (by enabling ATOC, so requires vista+ and a DX10+ gpu to have any effect)
just to make things clear, the problem with the outdated files isn't anybody's fault - basically, at some point for reasons unknown, someone made a so called "Premier" 1.18 patch, which is just the 1.18 patch with version checks removed, and some files missing. but as it seems newer than the proper, full 1.18 patch at first glance, way too many T2 re-releases ended up being patched by it, and the GOG build is not an exception (same goes for steam).
and a few fixes to TG as well;
TG_GOG_11jan2018_update (extract to your GOG 1.25 TG folder, overwrite. will reset any cam_ext.cfg tweaks)
-squirrel script now in the root, as people may want to run FMs without using TFix
-enabled smooth texture edges (by enabling ATOC, so requires vista+ and a DX10+ gpu to have any effect)
-a few fixes to some misbehaved objects in a couple of missions
