It just downscales at roughly the same rate the Downscaled Ships mod does it. I don't reckon miniatures did anything different from traditional downscaling, but I didn't size anything specifically according to that mod, no.

Simple question. The size of ships of your downscaling mod. Are the same of the Mod called (Migniatures)?
