    Hey, alright...glad there's more. I spent all night last night messing around with stuff just based on the first post and a post on Wilbur rivers in the overchuck tut. If waldronate happens to stop by and read this...is Wilbur going to support more import formats? 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.
