I've updated the pack with a bunch of new decals, including flattened versions for walls, and three map templates. 256x256 space, 512x512 space, and 512x512 jungle. These map templates have fog and sky settings set to max distance and have premade terrain outside the playable area. The space maps have the playable area on elevated ground so that when the camera is at ground level looking out of a hanger or window you won't see the a flat starscape at ground level. Yes there are now starscape decals and detail maps.
Anyone is welcome to add map templates in different sizes and terrain types.
There are pictures on the download page.
