Waffle,
I can import/export water to bitmap with no issues, the only issue I have is the file so large I cant modify it with my software.
Issues I have found:
1.Imported grayscale elevation is inverted, darker shades show up as higher elevation.
2.Mini-map does not work, the display is pure white.
3.Water changes require me to cycle the Low Detail ON/OFF for them to show up.
4.Object editor will not open, crashes about half way through loading.
I think I have stumbled across a few more but will confirm them first.
Edit:
Issue when dealing with the terrain gndtype.bmp.....
Open terrain, erase some water to create a large island.
Change terrain to any type, save and close TE.
Open gndtype.bmp with some sort of photo editing software.
Use eyedropper or set RGB to specific value and change whole bmp to that color, save to proper folder.
Open TE, load proper file and the change will not show up.
It does not look like the manual changes made to the gndtype.bmp show up properly. The displayed terrain ends up looking like a blend of two types. It certainly doesn't look like any of the the main terrain tiles. Can anyone else replicate this? All of the issues so far can be duplicated.
