Still working with photo scanned models here. It's amazing the detail that can be captured by stitching together photos to actually create a 3D model (I'm guessing with a fair amount of clean up by hand, but not really sure what the process is). Insects make great subjects for this.
What I really wanted to learn was more about shaders (materials) in Corona and how to build more complex ones. So I found a scan of a Rhinoceros Beetle that had no texture and built a whole scene having to build the shaders all from scratch.
I had a clear idea going into this about what I wanted (for once) with an iridescent metallic greenish blue feel and am pleased that I was able to see it all the way through. I learned a ton on this, though stayed up far too late creating it while my family slept. These are create in Cinema 4D using the Corona Render engine.
