Lumbermill. It can work for example as modern lumbermill. Animated - it uses workshops animations (when city is working on that plot - from the chimney starts to smoke). Around 190 triangles model. 256x256 (model) and 128x128 (shadow) textures (it can be 128x128 and 64x64, but i left bigger textures - it's always easier to resize it down). Thread
