Download this Cinema 4D Octane material here. This is not an official document from Formlabs and was created for learning purposes.
As part of my job at Formlabs as a UI/UX Designer, I often use Cinema 4D as a prototyping tool for rendering image placeholders. It allows me to quickly generate different content, compositions, and scenes when designing webpages and proves to be a much faster iterative process than going through the photo studio. Those renders can then be used to convey the vision to the photography team for the final image.
While of no real importance for placeholders, I have developed a liking at achieving highly-accurate and realistic results in my renders. Most recently, I have been fascinated by the very peculiar texture and properties of Formlabs’ 3D printed pieces.
Using the above photograph as my main reference, I tried to re-create the material in Cinema 4D.
I found a great Normal map by Alan Warburton, available on his website, which allowed me to replicate the horizontal lines as well as the subtle plastic-like grain and imperfections.
I added subsurface scattering to get the see through parts like the bottom supports, and added a roughness map for a more uneven reflection and gloss.
I’m blown away by the results and detail I was able to achieve. While the render still misses the subtle imperfections, scratches and print flaws to give it the photo-realistic effect, its overall look and feel are pretty close to the real thing. I think for a first try, the results are definitely convincing.
This material exploration has taught me so much about understanding how objects are seen in real life. From learning the resin’s index of refraction
