Trying to import a water map

[kel333]

I'm trying to import a water map that I made based on a king gen tutorial. I've used gimp and tried 8-bit and 16-bit PNG exporting grayscale. When I try to run the map with the import water map function in tarragon, it gets all the way up to 99% of importing and then crashes with no error message. Any idea what I'm doing wrong?



I've imported height.png and biome.png maps without issue... any ideas?

The most likely cause is an error on your water map.  Wrong size, no alpha channel, etc.

Note that Gimp doesn't export the transparency (alpha channel) by default when exporting to PNG.  You need to select the option to do so.

Yeah, I kinda suspected that. I don't have a lot of experience with this stuff, and this is my first attempt at making a map. Teragon is complex...

But thanks for your reply. I was able to import an earlier splat4.png so I could have my rivers, lakes and ocean without using "flat water" so my crevice would stay dry. Now I'm trying to figure out how to use "flood area" to dry out my crater. Or, add an alpha channel to my water map in gimp to customize where water goes.

Anything that is created after running the Create Flat Water Map will not have water.  Water is only added to terrain that is already there when you use that command.  If you look in the default presets, the crevice command is located after the flat water map and so would not have water in it.  You can move the crater after it as well if you wanted.  But flooding the crater with air also works.  Flood Area command - set it to air, set coordinates to the middle of the crater, set the offset to whatever elevation is needed to remove the water (10-30 probably is fine).

The flat water map is not the same thing as a real life water table.  It doesn't mean that if you dig a hole (in game or in a command placed after the water map is created) that it will have water if the hole is deep enough.  It's just a way to fill in low spots that are there at the time the command is run.  No changes to the heightmap afterwards will have water, no matter how deep those changes are.
