I'd like to be able to do up some clouds, tweak them, and then import them into Wilbur but I can't output to any of the formats with PS.
    Use PNG. In Photoshop, work with 16 bits per channel and save as PNG. In Wilbur, read this as a PNG Surface (File>>Open, select PNG Surface as the file type and your PS PNG under File name). If you get an error message along the lines of "attempt to read a PNG with 16 bits per channel" then you didn't select PNG Surface as the file type. Save the PNG data from Wilbur as PNG SUrface to get it back into Photoshop.

    Unless you really want some other format, of course...

    Step 5: The Mountain layer and the heightfield

    Hide all the layers except the heightfield layer and select it. (See Screen shot 2)
    Choose the select by colour tool. Set the feather edges slider to about 20 and the threshold slider to 50.(See Screen shot 3)
    Choose the lightest point on the layer and select it. An area smaller than the higher ground selection should be highlighted.(See Screen Shot 4)
    Unhide the hidden layers and add another one called "Mountain" on the top.
    Select Bucket fill and add a light grey texture. Once again the lighter the texture the more effectively it will pick up the bump map. (See Screen shot 5)

    Step 5 Continued.

    Select the mountain layer. Apply a bump map. (Filters>>Map>>Bump Map). Apply the heightfield as the bump map to the mountain layer. As can be seen from Screenshot 1 the elevation has been set to about 5 and the elevation has been increased to 5. Hit OK and apply the bump map. The result should look something like Screenshot 2.

    Step 6: What about a bit of water

    I know this was supposed to be a mountain tutorial but lets add some water.

    Add a new light blue layer below the land layers. Hide the other layers and select the bottom heightfield layer. (See Screenshot 1)

    Choose the select by colour tool (make sure that the feather edges box is unchecked) and set the threshold slide to about 60.(See Screenshot 2).

    Now click on the black areas of the rivers in the heighfield. This will select all the lowlying areas and the largest of the river channels.(See Screenshot 3).

    Unhide all the layers and select the (greenish) ground layer (Screenshot 4) and delete the selected areas (Edit>>Clear). Repeat this after you have selected the high ground layer. The result should look something like screenshot 5.

    Here is the same map after the colours have been tweaked, a dark blue border has been added and a forest included.

    If you do use this tutorial please post your results in this thread, together with any questions you may have about the method.

    The thing that I've been struggling most with is trying to get rid of the hard beveling on the rivers that Wilbur does. I'm pretty sure it's in the settings/values/numbers used but I haven't been able to find something softer.

    OK here's what I mean...the rivers seem to have an outer bevel on them, like in Photoshop. One side of the bank is shadowed while the other is highlighted...as if the sun were in the top left corner. The first screenie is straight from me following the tut (Fun with Wilbur 1), the second is the grayscale, the third is the grayscale (set to overlay) applied to the screenshot. The fourth is from torq's map. The fifth is torq's method (erosion cycles) where it is more pronounced. Is there a way to soften the effect when using incise flow or erosion cycles?

    The apparent bevel is the result of the step crfeated when excavating the river channel straight down. The lighting models in Wilbur and image editors then give the light/shadow effect as they would on any other kind of step. You can reduce the effect on the surface by using the Effect Blend setting on the Incise Flow Process dialog. You can smooth out hard edge on the step by using a blur operation on it. A combination of effect and blur can be very effective.
