The ability to choose figures rather than work by the integer ratios.
Example of the current issue:
Heightfield = 2048 x 2048, with 1 point for every 10m
Actual size 20480m (or 20k)
Intended 'Satelite' resolution of 1 px per 2m, thus requiring a texture res of 10240 x 10240
(Would of been MUCH worse if I wanted 1 px per 1m, as that would have to do over 50% more work than required at 32768 instead of 20480)
Only possible way to get this is to choose the 16384 and then 'scale' it down in a graphics programme.
If I was able to set that I wanted the 10240 then it may reduce processing time in L3DT rather than doing extra work that is not even wanted, and make for imagery more reflective of the final target.
