This is a jug made using a reference. Made using Blender 4.0.
The studio setup is not included in the package.
2 versions are included (one which is one mesh and other which has handle and the body as separate meshes, recommended to use the joined version).
Obj, dae are included but using the blend file is recommended because of materials, blend file has the procedural node setup while the obj and dae use a baked version from this material and are thus lower quality.
Materials are packed in the blend file.
There are no N-gons.
Image 1 is a render using cycles render .
Image 2 is a screenshot in materials view.
Image 3 is a top down view.
Image 4 is a matcap view with a metallic material so that you can clearly see the mesh.
Images 5 and 6 are wireframe views (there are no N-gons).
