This is a material I worked on as a bit of fun and a personal challenge. I wanted to push myself and try creating something more complex, using only height maps and displacement, no modelling involved. After I settled on making a jack o' lantern, I decided I also wanted a set-up where I could swap out the faces easily with whatever I wanted, which was a big success! This project was a lot of fun, and really helped me get a better understanding of height values, and how to work with distortion in UVs.
Overall, a lot of fun and totally not an effort on my part to keep the spirit of Halloween going long past the date. ;)
