Nice topology as shown in pictures. I built this vase by using loop tool only, not by modifying default object in Blender. I didn't use any plugins or modifier in Blender as well.
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 as per CG trader standard, parameters were verified by Kodama. I also attached screenshot of verification by Kodama for each model. However, I got problem with UV stretch. Total vertices: 384. Dimension: 22.8 x 22.8 x 30.9 cm, inner diameter: 18.9 as shown in sceenshot.
In Blender file has name scene, I already set up world with blue sky with white clouds, sunlight so it is convenient to make more images in outdoor scene.
Avaiable formats: fbx, glb, obj, stl. Images textures, UV map are in zip files.
Any questions about working process to build these models, any idea to improve models quality, please let me know
