Thanks, appreciated!
I’ve used a PBR clay material for the characters (albedo/diffuse, roughness and bump). The background has a plaster material, mixed with a Noise texture to spice up plain areas, and the ‘vomit’ only has a Noise texture.
Two additional things are very important for the look: I’ve used SSS for the characters and the vomit, and I didn’t only use bump mapping, but also added subtle true displacement.
