Hi
I use traditional sculpting techniques to create shadow art sculptures such as the one below but I am trying to use Zbrush to design the sculptures beforehand. Does anyone know if it is possible to cast a real-time shadow onto a flat plane behind the sculpture? The idea is to keep the light source fixed and then make small adjustments to the sculpture until it casts the right shadow. I know it is possible to create shadows while rendering but this would slow the process down significantly as I would need to render the sculpture every time I want to see if I moved a piece of the sculpture into the right place.
Does anyone know of any other software packages that may be suited to this task?
