Here are the layer styles I've made so far for things like buildings, roads, walls, n other stuff. Use em directly or for inspiration and remember to remove the drop shadows when ready to render up the final shadow since the shadows here are more of a placeholder. Land 1, land 2, and desert require you to put the style on a clouds layer. BTW, these are for Photoshop. To use these most effectively, place your buildings with the flat sides in the cardinal directions, apply the layer style, create a new layer, merge the 2 layers (this flattens effectively removes the layer style and produces a raster layer similar to rasterizing a text layer) then rotate the building to fit the street it is on. If a building is rotated before flattening then the style doesn't match the roof slope. To achieve other cool effects apply a new layer style on top of this flattened out one or use gradient overlays instead of bevel/emboss to simulate height as in the market style because not all roofs were built this way...read up on some architecture to see what I mean about roof styles, there's a link somewhere around here I think. If you stack different shapes on different layers and subsequently use differing layer styles you can get something like the castle or lighthouse on my fjord map. The castle has 3 layers, the stone base, the castle roof, and the lil turret roofs.
