There are 4 objects included:
The cookies have real-world dimensions (in cm), and their pivots are positioned for easy manipulation. Each cookie is a single mesh, but can be easily separated in Blender into individual parts.
The materials come in 2 versions:
The textures are PBR and consist of base color, roughness and normal. The cookies are as lowpoly as possible, while retaining curvature. UVs of the gingerbread aren't overlapping, but the icing is (to save space and increase texture detail).
The formats included are .blend, .fbx, .obj. If you unpack the Texture folders, the textures should be loaded automatically in the imported FBX and OBJ files.
