Post 9:Finishing the Land.

After the bump map we now have this. You can adjust the opacity of the bump map to make it less noticeable if desired:

This is OK, but it is a little two green for me. One option is to change the overall colour by adjusting the hue, and that would be that. Instead, we’ll add a dirt layer. This will be a combination of a filter generated mask layer, and hand painting the mask.

Create a new layer called “Dirt” and fill it with the “med dirt” colour. Add some noise (Filters->Noise->HSV Noise):

Now bump map this layer on itself to give a bit of lighting texture:

Duplicate the “Land Mask” layer, bring it up to the top of the layer stack.

and blur it by 50px or so:
