Common uploading issues



Model uploaded with no layers



When uploading files with more than 25 meshes, the meshes will be either combined into a single mesh or the upload will fail.

To avoid this, you need to combine group layers into single meshes or export model in separate files. Always aim to have the least amount of meshes and materials for optimal performance.

Vertex normals



Using one-sided faces is common in AR and other OpenGl, meaning that the other side is transparent.
If there are transparent parts or darker spots on your mesh, check its Normals.

Smoothing groups



Smoothing groups are a way to make lower quality models look more detailed.
Find model too smooth or not well defined, check the smoothing groups.

3ds Max - Modify>Smoothing Groups>Auto Smooth



Maya - Mesh Display>Set to Face | Soften/Harden Edges



Texture does not look correct



When your uploaded textures do not work correct, enable the UV map editor setting. This setting will apply a clear texture on your model and will help you understand the issue. When the UV maps are unwrapped correctly the pattern will be the same size through out your model with no clear displacements.



Pack UVs to 1:1 UV space


For CAD models, make sure that your UV maps are packed to 1:1 UV space.
