 ### Requirements
-When you export a model you need to make sure that it fulfills the following requirements:
+When you export a model it's good to know that we don't yet support all features.
+Currently known issues/not supported features from the Gltf format:
 
-* The model must consist of a single mesh
-* The model must use a single material
-* The exported *.gltf* file must use embedded mesh data. Mesh data in a separate binary file is not supported.
