As apart of Crypt Crawls art style experimentation, I decided to try and create dynamically lit 2D sprites inspired by RobotLovesKitty’s Bog Post. Using the sprite provided on the post, I was able to produce variants on it by playing around with the normal maps resolution.
This allowed for the sprite to still remain pixelated, but with more details. This makes the sprite look much more realistic. This additional layer of detail could be used to light cracks into the skeleton’s skull.

Currently, I am using Unity’s Standard Shader, which conforms to the PBR Standard.
