High quality scan using cross polarised light. As a result the texture captures the actual diffuse map of the croissant.
The model contains 4 textures ( Diffuse | Normal | Displacement | Roughness ) and it has a low poly mesh and clean UVs
The .c4d object contains a Redshift material that is ready to render while the FBX and OBJ versions use the 4 textures mentioned above. Some tweaking will have to be done in order to match your renderer of choice.
