Massive thanks!
Decided to go and buy the game because of this work (loved SH2/3 but had shied away from 5 due to its rep for needing modding) + the prospect of Sobers mod soup of loveliness
Unfortunately - same issue as DragonLord - my googlefu is weak as I have only found some slightly dodgy looking forum links to the Cab/Hdr file viewer...
Anyone got a link?
