After texturing my entire map, testing it frequently to ensure that it was appearing the way I wanted it, I pbo'd it and took it to another computer to show it off. In OFP, there were no textures, just white! I returned home, loaded Visitor, re-pbo'd it and it worked in-game perfectly.
After a lot of checking, I discovered that the virtual drive I was using ( Z:\) had to be running for my textures to appear in the game. The pbo is looking in z:\ for the textures, even though they're actually IN the pbo!
Checking the pbo in a text editor, I can see that all textures have the "z:\" path in front of them. Naturally I need to make the game look in the pbo instead. Can someone help with ways that I may fix this problem, as I don't fancy re-texturing the map!
The rest of the island is complete and ready for beta testing. Need help!
