This is St. Margaret of Cortona church. I used a model by M. Holewinski, this is actually his church. This is rendered with form·Z, and the recipe is simple: one direct light as the sun, some ambient light, and ambient occlusion. This is my very fast exterior rendering recipe. The textures are the pre-defined ones that come with form·Z, tweaked a bit for this render. I also edited, compiled, or created the materials that ship with form·Z and bonzai3d.
