Yesterday, suspecting that there may be a problem with the Photoshop conversion from RGB to Greyscale process, I re-made my map_T and map_h in Gimp.
The textures came out much better......all nicely layered like a cake....going from the coast right up to the mountain tops........I used a different texture for each to check (lowland 0,1,2,3 midland 0,1,2,3 etc.)
One would expect mount 3 to be the highest !......not......country 0,1,2,3 are higher... :?
My water levels were still too low..??? The sea level I was able to raise (by opening map_h in Photoshop and in the 'levels' moving the left hand slider to bring it in line with the first elevation data.)
Trying to get the rivers and lake to be the correct height doesn't work...it just makes ugly canyons
BUT...the biggest problem is.....I cannot get ships to place anywhere upon the map!!!...even after getting the sea level correct....
whereas.....armour and vehicles can be placed....and waypoints placed to take them across the sea and rivers....but they shy away from mountains and their waypoints bend around them ( just like normally ships do if we place their path near to any land).....
I'm really at a loss with this problem
