@Tentha The game loads the map file
Like Origins, it will be dlczm4.ipak or something like that.
I tried to load it on TranZit with a mod menu, but it was unsuccesful. If you only edit the textures, it won't work. But I have never tried to load Origins' Ipak file while playing on TranZit.
According to me, if a GSC script can't load a specific file, it won't be possible.
