The Studio checks models for compliance with the glTF specification using a validator from Khronos. Click the link to view any errors and their descriptions.
Most of the errors are listed in the document. If you haven’t found a specific error here, please check the model with the GLTF validator.

How to fix |
|
| Not Valid gltf/glb(Reason: ...) | “Missing image URI. Check names of files in the uploaded archive. The names shouldn’t contain spaces.” |
Make sure there are images in the archive. Open gltf file in text editor, go to the 'images' block and make sure images URIs are associated with the correct images file and the same names are used.  |
| "Missing image file {}." | Make sure there are images in the archive. |
|
| "Missing default scene." |
Make sure there is a default scene in the file. Open gltf in text editor and go to the 'scene' block.  |
|
| "Missing scenes." | Make sure there are scenes in the file. Open gltf in text editor and go to the 'scene' block. | |
| "Model {} loading failed." | There are unsupported charters and symbols in the file. Make sure there is no space in URIs in gltf. If there is any, replace with an underscore. | |
| "Unsupported format." | Make sure archive has gltf or glb file. | |
| “Model without polygons is not supported” | Make sure mesh is included into a gltf file. | |
| "Render models pack contains 0 render models" | ||
| "Error in {} mesh: indices must be nonempty." | Try to re-export file from another software. | |
| "Error in {} mesh: POSITION attribute is absent." | Try to re-export file from another software. | |
| Error in {} mesh: TEXCOORD_0 accessor type must be FLOAT. | Try to re-export file from another software. | |
| A normal map is missing. Add a normal map to the model. | Normal map is required. If a model doesn’t need a normal map, create a small one-color (RGB[128;128;255]) texture. |
|
| Error in {} mesh: index buffer is absent. | Try to re-export file from another software. | |
| Only one UV [0, 1] layout per item is expected. Detail information is located here https://wanna.helpjuice.com/en_US/3d-model-requirements/general-3d-model-requirements | Make sure there is only one UV-set. | |
| UV not found. Please add UV set to the model. | Make sure UV map is created and each geometry object is associated with a UV island accordingly. | |
| UV tiles are not supported. Do not use UV tiles during the model development process. | Make sure all UV islands are in one square [0..1] range. | |
| Multiple UV coordinates in one vertex are not supported. | ||
| KHR extensions are not supported. Do not use KHR extensions during the model development process. |
This error is shown if the workspace does not support any extensions. Make sure no KHR extensions are used. If there are any, open gltf in a text editor, go to 'KHR extensions' block and delete it. Please note, the general model view can be affected. |
|
|
Extensions: KHR_texture_transform are not allowed. (can be different unsupported extensions) Allowed extensions are KHR_materials_clearcoat, KHR_materials_ior, KHR_materials_sheen, KHR_materials_specular, KHR_materials_transmission, KHR_materials_volume, KHR_materials_emissive_strength, WNB_materials_gem. |
If at least one KHR extension is supported in the workspace, the error will indicate those that are not supported, along with a list of supported ones. A list of supported extensions can be found here. For instructions on how to remove an unsupported extension, see here. |
|
| Geometry was not detected. Please add geometry to the model. | ||
| Models with non-square textures are not supported. | Make sure a square texture is used. If there are non-square textures in the file, divide them into separate square textures. | |
| The model with Published status can not be replaced. Rename the model to upload. | Please rename model ID you're trying to upload. | |
| This ID already used for another model. Please rename model ID | Please rename model ID or delete an existing one. | |
|
Currently publishing process is running in this workspace. During this process any changes to existing models are not allowed. Details:Replace existing is forbidden during the publishing process. |
Publishing process is running in the workspace.Try again later. | |
| Model {model} has too many polygons: {num_polygons}. Please reduce it to less than {max_polygons}. | ||
| File is too large {file size}. Please reduce it to less than 50 MB. | ||
| Archive with more than 1 model is not supported (bags/watches). | Make sure the archive file has only 1 gltf/glb. | |
| Archive with more than 2 models is not supported (sneakers). | Make sure the archive file has 1 or 2 gltf/glb. | |
| Choose the right and left sneaker. | Choose left and right sneakers accordingly. | |
|
[3D Viewer] Pixels count for model exceeds (found 41 000 000) 38 000 000. [Try-on] Pixels count for model exceeds (found 21 000 000) 18 000 000. |
Make sure textures for different materials that are placed on one UV map are not duplicates. Try to use less textures and make sure texture resolution is set according to the requirements. | |
| The model with more than 75 primitives per model is not supported. | Combine nodes into one object. | |

How to fix | |
| The shoes was fit incorrectly on the foot. Check please if the model matched with the specification. | The shoes may not have been positioned correctly. Scan the QR code to verify this. Additionally, double check that the model of the shoes is correct according to the specifications. | |
| The automatic fitting of the shoes on the foot did not work. Check please if the model matched with the specification | The shoe model needs to be corrected according to the specified requirements as the automatic positioning of the shoe on the foot did not work. After the correction, it must be tested again. | |
