What would cause that i cant click "Create" button in Map_c toolbox
Do i have to leave lakes and rivers in completely black?

Not being able to ´create´ in the mapC_toolbox can have any number of reasons.

One of my recurring mistakes in the sizing of the maps, starting with the very basic color and gray dems. They have to be sized in multiples of 32 pixels, both in height and width, starting with the smallest size map and going upwards ... if you´re off by even 1 teensy pixel then the map(s) won´t load or one of the utilities like mapC_toolbox may not recognize the map you are choosing either (in this case it could be either my_mapC.tga or map_h.tga).

The colors of the rivers, lakes and ocean in my_mapC.tga have no bearing on mapC_toolbox working or not. Even if you were to draw your rivers and water in red, map_Toolbox will recognize a correctly sized map - but you will get an utterly ridiculous placement of water ... If you draw water in white, you will simply get a map without water.

I would bet that there is something amiss in the pixel size of your maps. Check that they are all multiples of 32 pixels on all sides.

Fin_ace,

Are you using the latest version of Map_c Toolbox? Latest version is 1.1.0.

Is the "Align" button highlighted? If so then your map is not aligned on mulitples of 32x32 pixels. Hit the "Align" button to crop your map (surplus right and bottom pixels are truncated). This will give you a correctly sized raw map_c file. You should be able to hit "Create" then.

As agracier says, colour doesn't matter - however I strongly recommend using an uncompressed grayscale map :wink:

RGB values less than 128 = water
RGB values greater than or equal to 128 = land
RGB values close to but less than 128 = shallow water

Make all values equal to or greater than 128 = 255, this will reduce the size of you "cooked" map_c file considerably.

EDIT: Come to think of it, do values between 128 and 255 do the same for heights as values between 0 and 128 do for depths? Hmmmm..........smoother maps?

Don't hesitate to ask - I'm the developer of Map_c Toolbox.

Stick in there Fin_ace, build them maps
