I think I've got the dirt textures and some of the trees sorted out now. There's a lot more stuff in the pipeline, but I'm on my way to bed right now, so this is a shot of my screen as I close everything down.

That looks fine to me :)

That looks better :)

This is colour 60 on my own map.

The simplest way is probably to add a Wall Shadow, Point Light Finalize sheet effect to one of the last sheets in the list, check the Shadow Color is ambient light box and pick a nice bluish colour. That way you can turn the effect on and off.

Can you show us a screen shot of the Bevel effect in edit mode, so we can see how it is set up?
