Uploading 3D Models

Uploading 3D models to the Sayduck Platform is simple, either drag and drop your file(s) to the product page or click on Upload logo in Meshes.

Uploading & Processing

There is no hard product data size limit, but in general the maximum upload size is 50MB per 3D file (which might contain multiple parts). Files over this threshold will not be processed correctly.

Merge meshes/layers that share the same materials
10 geometries/meshes or less
200,000 polygons or less

For optimally performance of the 3D viewer and Augmented Reality, we do recommend to keep each products under 10MB, including textures and all. As a reference, iPhones start having serious difficulties in AR for models over 500k polygons.

Import formats

The Sayduck Platform supports the following formats: OBJ, FBX, GLB, GLTF, 3DS, 3MF, DAE and STL. We strongly recommend you use OBJ since it is our best supported and most tested format. GLB and GLTF are great alternatives which also support PBR materials.

Recommended file formats

.glTF (local, remote, embedded)

Other file formats (experimental)



Uploaded meshes will appear to your Meshes and to your Scene. You can also choose to add additional meshes or meshes that you have deleted back to the scene.

Drag & drop the mesh icon to the 3D viewer to add it to the Scene
Click the + icon inside the Scene to create a new Node

Camera Ignore

Meshes with camera ignore will be ignored in the initial camera angle.

Camera ignore will not work on meshes that share a group in the Scene Hierarchy

Replace Mesh

Replace Mesh can be used to easily update individual meshes. Uploaded mesh will automatically replace the older mesh in all active 3D scenes.

Upload Units (only for obj)

Upload unit determines the size of your model on upload. The Sayduck Platform uses centimeters (cm) as the default upload unit.

The upload unit should match your export units used in your 3D modelling software.

3D Data Dimensions

You can confirm your model size by displaying 3D data dimensions.
