Missing textures in file
It seems the textures were not packed correclty. If filepaths to the textures are complex or have non-standard characters, Blender might have problem packing these.Blender also doesn't support packing UDIM textures and therefore by now it's not possible to upload UDIM assets. Please try to pack your textures manually and after upload, try to download your asset in a new file, to see if the upload was correct.

BlenderKit HDR library collects only usefull HDR maps
Low range HDRs aren't HDRs
Images that have 8bit depth or their values are capped between 0 and 1 aren't real HDRs

Insufficient quality of uploaded asset
What is our quality limit for accepting assets?
UV maps names shouldn't be included in the material
UV maps names shouldn't be included in the material when you upload it.
Asset fixed during validation
Since the problems were minor, we fixed them for you.
Improve thumbnail quality
Improve the thumbnail quality of your asset.
Material bump intensity shouldn't be too strong
If you overdo bump intensity in Blender, you can get not only unrealistic look, but also shading artefacts.
DirectX normal map
Your normal maps don't match the OpenGL standard. The material will not look correct after being downloaded from the BlenderKit.

Material too simple
We try to keep only high-quality materials.
Improve material IOR
The material doesn't have the IOR of the material that's in its name.
material Subsurface scattering radius
Subdivision surface scattering radius in Blender is in metric units and should rarely be over 0.05
Unconventional Thumbnail
Unconventional Thumbnail will make the BlenderKit base non-uniform.
material PBR setup
When Principled shader setup is incorrect.
Wood mapping on model
The wood should always be mapped with the grain oriented parallel to the longer side of the wooden part, then the material in the BlenderKit database will look great.
Plant leaves with the alpha channel overlapping
Leaves with the alpha channel overlap, this can lead to an unrealistic rendering of the plant.

Model Topology Issues
There are topology issues in this model, like double/overlapping faces, double vertices, non-manifold faces, subdivision surface artifacts, or similar.
Wrong meshes or missing parts
Some parts seem to be missing, for BlenderKit uploads, be sure everything is parented to a single parent and not to include (unparent) any extra hidden meshes.

Why applying scale (and rotation) matters
So many reasons to apply scale whenever you can in Blender 3D!
Model unrealistic shape
The shape/proportions of the of the object aren't realistic. Check reference pictures to study more the real shape of this object.
Multiple assets together
Please split this asset in several assets.
Unrealistic texture size
Upload your materials with correct 'texture size' parameter
No materials on model
You didn't use any or only too simple materials.
