I did this piece for an Art challenge. We had 8 weeks for start to finish. I used Houdini, Renderman, and lot of patience for this one. The mesh lights almost put me in the hospital ;-). I used a cryptomatte technique for the first time... and it was awesome. Again, I really love doing bumpers.
There is a presentation I did to go along with this project: https://www.youtube.com/watch?v=hZI8wbsvdPE&t=14s
This was for an Art challenge. This was also dedicated to my friend's newborn child, who is named Luna.
