Ok so I put all the stuff I had into the UHD map making folder in the lead post. With the dark ocean stuff, the Units with their flips, and some of the extra stuff for layering relief clocked in right around 200mb zipped. Here is the file again, the one that has all the relief elements and such.

When I removed all the extraneous stuff from the UHD World War II Global folder for a lighter footprint file that one clocked in at about 81 mb. Here is the game folder...

It has no relief as a single image, but that should be easy to reconstruct from the reliefTiles folder. Provided the other Customizing package lives somewhere people should be able to get at what they need from that, like to edit the relief, do different borders or different styles, retint the units or whatever. I removed the v3 48px units, since those can be grabbed from the regular global download. They're still compatible, so you can switch the units from one map to another (48px mono tints or 54px duo tints), but it trimmed down the overall filesize so hopefully the install/load is a bit faster.
Let me know if that makes sense for ya
Have a fun weekend!
