How can I get a map builder for modding DoD?

I want to create mod for DoD, but I didn't find any tool that will help me to make maps in dredmod.com

Where can I find those tools?

I know maps are mostly random generated, but is it impossible to create a map beforehand?

 

You do not build maps. You build rooms, which are then drawn from to generate a map.

Rooms can be built with something as simple as notepad.

 

So, if I want to make a big outdoor world with grassy landscape, I make big 1000*1000 gird and specify which texture will be splatted on it?

 

Well, something like that. Though making a room that big might not work well with the game.

 

*I'm not sure how big the dungeon grid is, but it's generally not a good idea to exceed it. 1000 x 1000 is far too much.

*The dungeon's tileset is determined by what floor you're on; the tilesets are currently unmoddable. If you wanted to create a grassy knoll, you'd have to define a custom engraving for each tile of floor, and a new one for each type of wall completely. You could do it, but it wouldn't be worth the tedium, honestly.

 

So, unmoddable it is.

Did you mean 'one unit of tile texture' by engraving?

 

It's about 90x90, maybe 100x100.
