Nice topology as shown in preview images. Bread shape was made by bridge loop tool and subdivision modifier level 1, not by modifying default object, no other plugins, no more modifier in Blender. All images textures were made by myself. Make sure model looks realistic and light enough for room scene. Render engine: Eevee.

Only quad in model, no N-gons, no triangulates, no vertices with more than 5 edges, other standards also meet CGtrader requirement. No mark seam during UV editing, no overlapping UV. However, I got problem with UV stretch. Please see preview image, I also attached screenshoot for verification from Kodama. Total vertices: 994. Dimension: 40 x 15 x 8 cm.

I also uploaded Blender file with procedural nodes to make cucumber peel material, ready to bake image textures( Diffuse map, Glossy map, Normal map) . Please see preview images for your overview. In Blender file, I already set up simple lights to render room scene. However it may be better for night time scene

Avaiable formats: glb, stl, obj, fbx( both embed and no embed textures). UV map, Image textures are in zip files

Any question about working process, any idea to improve model quality, please let me know
