@CactusCartocratus i indeed made a version with rivers,and also topography with some rivers.
but i made it for my version of vt-bam which is less wide than the current one,i can send here my PDN project that includes a map of all historical borders i could find on this forum,better topography with rivers more visible,and base map with visible main rivers,and everything else that is in the vtbam project but it's just less wide than the original one.
and it's just europe unfortunately for you maybe, some french and spain rivers may be incorrect.

although,you can try widening the river map to the normal version of the vt bam (just make sure to select nearest neighbour mode in Paintdotnet)
