hello all, i am planning to use unreal engine to the UKOWTP better known as the (United Kingdom Open World Transport Project). this will feature:
all cities from the united kingdom
all train operators
london underground
supertram (Sheffield)
Metrolink (Manchester
SPT subway (glasgow)
london overground
DLR
croydon trams
midland metro (wolverhampton and birmingham)
emirates cable car (june 2012 onwards)
tyne and wear metro (newcastle)
NET (nottingham express transit)

a feature will allow you to start any year (from 1970) and in any city you choose.
now comes a question, will anyone be able to help me create this? i need help creating people, assets and collecting sounds of trains buses trams and other vehicles!
