Quick little video on how to edit height maps, prefab placement, road placement and (unsuccessfully) biome placement using the new A17 world system.
Enjoy.

It's dtm.tga and if it's missing, then you can just make one in a graphics program that can export in tga format.

ok thanx for help! Using a .tga still works.
Now I ve some more questions:
Where can I get a .tga with 16k size or do I ve to stretch the 4k one ?
Another thing is: I tried to make a world with water an islands so I set the
waterlevel in water_info.xml to a higher value:
( <Water pos="0, 48, 0" minx="-2048" maxx="2048" minz="-2048" maxz="2048"/> )
That seems to raise the water level like I expected BUT prefabs and streets still need to be generated under that new conditions.... how can I do that ?
EDIT: Raising water level by editing the rwgmixer works for creating a water world like i want it but generated world does not contain roads nor prefabs.

I tried opening the dtm.raw using gimp with the 2 suggested raw plugins, as well as ufraw, still no luck. I was able to get the files to open in ImageJ, but it doesnt want to register any changes in the file even after deleting saves for the world and all that. I can see lines ive drawn on the file when i reopen it editor, but no changes show on map.
Yeah fair enough Guppycur. I've moved away from wanting to edit the generated heightmap now. I'm now using L3DT Pro for creating the heightmaps. It exports in 16bit png's though.
I haven't as yet got a chance to do it, but thinking to follow these steps?
- Generate a world of the right size (8192 in this case).
- Delete the raw file.
- Plug in a dtm.png file (which must be an 8bit PNG greyscale image)
- Remove any region files (if they exist)
- Load up the game and launch the map
Sound about right?
After I get this working I'm going to see if I can write an application that will (using the png heightmap) go through all the POIs and elevate them to the correct height.

I think the raw files are 16bit; I got Minecraft blocks when doing 8bit.
But yeh pretty much.
I use http://terrain.party to grab a file, and edit THAT file, doing a save-as in Photoshop... Always editing the open file, never the saved file... Delete .rg files, test, repeat.
Also, Gaia (a unity app) also exports height maps, and it's kind of nice for terrain terraforming, AND it's close if not the same to what madmole says they're going to use.

Great, thanks mate, I'll try with the files straight out of L3DT then and see how I go.
Incidentally, I've put the heightmaps on my google drive : here
Ok, I don't have Photoshop. I'll try with Krita instead, but given I don't need to convert to 8bit I won't need to edit initially.
Looked up Gaia, looks like it's a paid app yeah? L3DT Pro is essentially free (perpetual 72 day trial), have you tried it? I'm just getting started with it, but it does have 3d editing capability.

I picked Gaia up for like 5 bucks on a humble bundle deal once; suits my needs and I'm not great with change. 
But I find it only good for the initial random generation of terrain plus the stamps, after that I'm using straight unity to flatten, raise and lower terrain.
The workflow from start to finish is intense, and is a driving force behind me waiting til gold to do another tut.
I got tired of free apps for photos so uh, acquired Photoshop just for this purpose... It's just easier.

Yeah fair enough, I'll have to keep an eye out to see if it goes on special at all.I picked Gaia up for like 5 bucks on a humble bundle deal once; suits my needs and I'm not great with change.

I bet, which is why I'm going to try writing a program to (at the very least) do the heavy lifting. I mean at the end of the day I wanna play too.
Each their own, being a Dev I eventually steered away from that practice especially when (up until now maybe) Gimp, Blender etc do everything I needed.
Amen to that.
Hey mate, I need some help on the smoothworldall front. I used the height maps I generated with L3DT tonight, and they're all Alpha2\minecrafty, Is that because they're 16bit? or do I need to use smoothworldall? And if so, how exactly do you use it? Do you load up the game map first? But then delete the region files?
Cheers.
