Thanks Daisho :)

If you think of more, be sure to add them as a new comment or I might not see them.

I've always found that the way to start a new style is to get the textures right. With this style the colours are more or less already dictated by the fact that they must be similar to the overland style. That just leaves me with the task of getting the actual texture correct.

Here is a first shot at the 4 grass textures. Those are Bitmap A buildings for a sense of scale. The Darklands ones will be nowhere near as clean and well maintained. The grass is probably long grass, but then - who is going to mow the grass in a Darklands City?

When you open FT3 right click the icon and pick Run as Administrator. That should give you the required permissions.

That looks better :)

I can't see the numbers in your nodes there, but I think you can play with the contrast between the black bits and the fiery bits or even change the pattern altogether by altering the Fresnel setting, and by playing around with luminance and changing the source of the Fresnel texture coordinates. Here is an alternative arrangement.

Oh yes, you can find the strangest things on YouTube!
