Step 2: Modifying the height field.
Open the greyscale map in Gimp. In order to increase the contrast and make the elevation effects stand out more it is necessary spread the grey map over the full range of black to white. To do this open the levels window (Colors>>Levels). The levels window is likely to look something like the first screen shot.
Pull the sliders inward to coincide with the beginnings of the curves on the graph as shown in the second screen shot.
Once you hit OK the result should have higher contrast and look something like the third screenshot below.

Step 3: The Ground Layer and the Height field
In this step you will create three distinct ground layers and apply varying layers of bump to them in gimp.
Firstly create a new layer above the greyscale map as shown in the first screenshot Completely fill it with a light green colour. You may have to alter the mode of the image to RGB to get colour (Image>>Mode>>RGB). Make sure that "Fill whole selection is selected". I have used a light green texture that is not too uniform, as can be seen from the second screenshot.
Then select bump map (Filters>>Map>>Bump Map) and use the greyscale map layer as the bump map as shown in the third screenshot. In the bump map window adjust only the elevation to around 38. Then hit OK and you should get a result similar to the fourth screen shot with the rive paths clearly evident.

Step 4: The High Ground Layer and the Heightfield
In this step we will create the next level, or higher ground and appy the bump map to it.
Firstly hide the ground layer you just created and select the heightfield as seen in the first screen shot below.
Then choose the "select by color tool" and check the "Feather Edges" box. Move the feather slider to about 30 and the threshold slider to about 90 as shown in the second screenshot. Then choose the lightest point on the heightfield and select by colour as shown in the third screenshot.
Then unhide the light green ground layer. Create a new layer above it and name it "High Ground". Then select the new layer it as shown in the fourth screenshot.
In the map window use the bucket fill tool to fill the selected area with a brown colour representing higher ground. I prefer to use lighter colours as lighter ones show off the bump map more effectively. The result should look something like the fifth screenshot.
The use the same bump mapping technique as in Step 3, applying the bump map to the new "High Ground" layer. This time the elevation is decdreased to

Here is the last screen shot that was supposed to be in the previous post.

Hi, Torq.
I'm currently compiling your tutorial into a PDF document and have a request / question for you.
Your fifth post on page one is incomplete as shown below.
Would you mind editing the post and completing it so I can include the necessary information for this step?
Thanks!
Regards,
Gary
In the end you will see, you is you and me is me.

Hey Vandi!!
Congrats on the new award!!!!
I am just guessing here but I do believe that you are the inaugural recipient
I am looking forward to that PDF too. I will be playing around with this one quite a bit in the future
Maybe you should start a sticky thread with links to the PDFs for all the tuts you are doing. Would be REAL useful I think
*hint* *hint* to any cls out there

Torq: Excellent tut - I shall rep and 5 star it in a mo.
Vandy: Cool badge ! Yes we should have a sticky list of transcribed tuts, preferably with a link to the tut thread too. I am guessing that you would need a post per tut or else you would run out of attachment space.
I have created the height map using wilbur and am stuck on Step 3. I make the new layer above the greyscale map as shown in the first screenshot and fill it with green. However, I can't get the background layer to combine with the green layer in order to show a green layer with the rivers. What am I doing wrong? I can see the green level "above" the height map, but when I try to do the bump map the result isn't in color. I have checked RGB.
Also, it seems like Wilbur makes the same height map every time I try to create one. Is there a quick way to change how the elevation is formed?
