Okay so I was planning to start a server but I need a map for that. I would like to make my own personal map and not use the vanilla one. I read from another thread that to make map I could use something like paint or gimp and after that some bitmap converter. Then slab6 and voxed.. But as I can't find any bitmap converters that could convert other files to bitmap and not other way around I need:

1. A good bitmap converter and more information of way like this to make maps.
------------------------------------- OR -------------------------------------
2. Other way to make maps (I wish it was simple cuz I'm not very skillful voxed user).

Ps. I'm not gonna first make the server and then go there and change the whole server one block at time to change it from vanilla to custom.

You can make basic terrain with bitmap converter then open it in voxed, press "U" and place prebuilt buildings, trees or whaterver you want.

Prefabs are made in SLAB6 and saved in kvx format.

Any links to bitmap converters?

And can I change the height of blocks with bitmap?

And yes you can change the height of the blocks with bitmap converter. It is for it.

Use a shade from 5,5,5(lowest) to 250,250,250(highest)

Thx. That helped alot. :D
