Creating planet X300D4 II

To add a "Coruscant"-style city simple model it in blender and either parent the city directly to your planet or render a diffuse/bump map out.























To create the lightmap for the night, I firstly rendered out a textured version (simple cloud texture) with transparent background and then add lights with GIMP's sparks brush on a new, transparent layer. Just play a bit with the sparks brush setting for brush size and occupacy.
