Well, I am trying to make a part of the world I'm making, but i can't find the right editor/modeller. I Try'd T.ED, but it didn't went how I wanted it ( cursor did very wierd when using tablet ). I tried EarthSculptor, but it didn't export DBT format and the heightmap didn't work in DGDK. So now I am trying to find a editor that exports to .DBT and that has tool instead of the middle mouse wheel and a very slow movement rate.

Already thanks for your help and reading this.

Height maps are a great way to go about creating your terrain, and if you really need more precision/height difference, color maps too. I guarantee you height maps work in DGDK, you're just not doing it right. It would advise you make a post in their board for more help.

I used http://www.freeworld3d.org/ in the past. It costs $20 but was pretty good for me at the time.

But seriously, all you really need to do is get out your favorite paint program, draw a gray scale layout of your terrain and load the map into DGDK. If your clever enough, you can create a mini program to read the file constantly (checking for updates) so you can work with it in photoshop and see the changes in real time.

Well, right now i'm trying to make a height map in photoshop, and i'm making a terrain in eartsculptor, both are in heightmaps.

But what are color maps, and how do you make like caves???

Caves are not possible using a heightmap. And why do you think? A heightmap is a top down graphical representation of the values of different heights on your map.

It's best to use a modeling program to make your caves. If you had the time/knowledge, you would probably program a level editor to help you with this but you'll have to do it in an external modeling app and import it later. You can still use your heightmaps for the world, but just make a large 3d model and plop it down somewhere on the world.

You wouldn't need to model the cave floor if you don't want to. If you did, you can make your heightmap really low as to cradle your whole cave model. Get what I'm saying? Or should I draw something to help explain it?

you could model the entire map in blender make a plane, scale it out then subdivide it 5-10 times. then select one face and move it up. after a while you have a map. you can also build caves/statues/trees/anything else onto it.

That's a pretty tedious to way to do it though. Unless Blender has a soft selection tool or something.

@Sid: Yes i understand that you can't make caves in heightmaps. It's just that maybe there were other ways, but I did make some sort of cave in blender and it works just fine. And now i'm making my map and stuff, i just have one question left, you said if I wanted precice height difference i needed to use color maps, I think i'm gonna do some research on them, cause they seem intresting.

And thanks for all your help and time for reading my noobish questions.

Heightmaps using grayscale which only can go up to 255 per pixel. Color maps combine the three channels, RGB, to make the highest possible number 16581375. It's much more accurate and gives you a larger range.

@Sid: Well, searched google and didn't found alot of information, my biggest question about color maps is, what color represents which height, like does blue come after red or is yellow after red etc. And about the heightmaps, right now my heightmap+tex+detail are in png format, but when i try to build at the build terrain i get een error box saying 6. Do i need to change the format of my files or does the problem lies elswhere??

I think it goes (0,0,0) through (255,255,255). Meaning the first value R will go up to 255 (so it would be 255,0,0), then the G would go to 255 (so it would be 255,255,0) and then the the B value would go all the way to 255,255,255.

I guess that would limit the combination's to 765 then? I might be wrong on that 16581375 thing. In fact, I'm pretty sure I am now. At any rate, 765 will give you a much wider range and accuracy.

TBH though, a grayscale heightmap will probably suite your needs.

And I have no idea, you'll have to ask that in the DBP board with a more detailed question.

Or 1 in the green channel represents 255 in the red channel and 1 in the blue channel represents 255 in the green channel such that (255, 255, 255) = 16581375.

[Edit]Just to clarify, I think what I'm trying to say is that its a base 255 system as opposed to standard base 10.[/Edit]
