It’s also a good practice to double-check your export settings.Apply modifiers: If your model has any modifiers, like Subdivision Surface or Boolean, apply them before exporting to ensure the correct geometry is included in the exported file.

Apply transformations: Before exporting, apply any transformations (scale, rotation, location) to the model by selecting the object, pressing Ctrl+A, and then choosing “All Transforms.”.

Incorrect UV maps can lead to distorted or misplaced textures on the exported model.

Inspect UV mapping: Double-check your model’s UV mapping to ensure the textures are mapped correctly to the geometry.

Also, make sure you’re using supported material types for glTF exports. Missing or improperly assigned textures can cause broken appearances.

Verify materials and textures: Ensure that materials and textures are correctly applied to the model in Blender.

If not, review the Blender console for any error messages, as they might provide useful information about the problem.

Check for errors: Re-import the exported glTF file into Blender to see if it displays correctly.
