No but I doubt it will... adding detail maps on another texture level is what I'd normally do but I don't know how to save blended layers to a model, or even if it's possible.
Quote: "Also, just so I know. How EXACTLY do you tell if the normals are flipped just by looking at the model?"
I just loaded the model using this code (EDIT: You can see it's flipped because you can't see most of the model from above, only from below where the 'lakes' are convex instead of concave):
sync on : sync rate 60
autocam off
set camera range 1,100000
position camera 2000,2000,2000
load object "tropics256.x", 1
do
camD#=mousemovez()*.1
camX#=camX#+mousemovey()*.3
if camX#>80 then camX#=80
if camX#<-80 then camX#=-80
camY#=camY#+mousemovex()*.3
rotate camera camX#,camY#,0
move camera camD#
sync
loop
