I created this ballista as part of my assignment at ThinkTank Training Center School, and it's my first full prop made entirely by myself. It was a fun and exciting experience, and I learned a lot during the process!
I used Maya for most of the work, but I sculpted the bone in ZBrush and added textures using Substance Painter. The final rendering was done in Marmoset 4, and I also have a screenshot showing how it looks in Unreal Engine.
