Nice topology as shown in pictures. I built this vase by using loft loop tool and subdivision surface modifier level 1, not by modifying default object in Blender. I didn't use any plugins either. Images textures were made with GIMP.

No mark seam when UV editting. All images were rendered with Eevee. Render quality as shown in pictures. Good enough to use in living room scene or game assets or for outdoor scene.

Make sure quad only, no N-gon, no triangulates, no vertice with more than 5 edges in model, no UV overlapping, no stretch UV as per CG trader standard, other parameters were verified by Kodama. I also attached screenshot of verification by Kodama for the model.

Total vertices: 1774. Height: 92.5 cm, bottom diameter: 18.6 cm, body diameter: 33.7 cm, Top hole diameter: 26.2 cm as shown in sceenshot.

2K textures: Diffuse, Glossy, Roughness, Normal. Material were baked in textures maps, so it is very convenient for users to set up. Please see preview images for more detail. In Blender file, I also set up simple lights and for rendering more images. Render engine: Eevee.

Avaiable formats: fbx ( embed and no embed textures), glb, obj. Images textures, UV map are in zip file.

Any questions about working process to build these models, any idea to improve models quality, wanna know how to set up textures for glass material, please let me know
