By default UP 2.01 uses the same QMB maps as stock 4.09m, but you can select QMBPro from the JSGME mod enabler. I've not tried it yet myself though, so I don't know how well it works.
It works quite well, but there is an additional step (or three) to be taken in order to see/experience the new maps. Complete documentation in the form of various "QMBxxx" files can be found in '...\<Your IL-2 1946 Folder>\Ultr@PackDocs\'.
Quick method:
- Open '...\<Your IL-2 1946 Folder>\Quicks\QMBMaps.ini' in a text editor, remove all the "//" slashes in front of the various lines of text; save the file.
- Open JSGME, enable the "00_QMBPro_PAL" mod. Close JSGME.
- Open your modded IL-2, select Quick Mission Builder from the main menu and have fun exploring the multitude of maps.
Note that not all maps will work with all the various mission types (Armor, bridge, strike, etc.) This is because several of the newer maps may only have a pair of red/blue 'None' mission templates available. Or they may not have any mission templates at all. Or ... in some cases QMBPro_PAL includes maps that aren't in UP 2.01, you may need to manually add them.
So don't be disturbed by any error messages you may see, usually those messages just mean that there is no mission template available to load or the selected map is simply not available.
