A cartoon style rainbow cake with fingerprint marked icing.
If you want a cleaner render, simply remove the texture from the roughness and bump channels of each material.
PBR material, textured to create fingerprint marked icing with pngs for roughness and bump.
Modelled to scale.
All objects and materials logically named.
Subdivision modifier can be added for extra smoothness with a little distortion to the UV mapping.
The fingerprint texture is created from a Creative Commons asset from cgbookcase/textures/fingerprints-01 (great resource).
HDRI used in render not included - “cinema_lobby’ from Poly Haven (another great resource).
