3D models of Ray-Ban glasses and a leather case created and textured in Blender. Modeled in quads with Subdivision. The models were tested in Unity as FBX (see previews). I have no means of testing other formats, so they were exported from Blender as they were. Relatively low poly count (32k). All moving parts are rigged with FK bones.
Available formats: BLEND, FBX, OBJ, GLTF.
