To use an Expivi product for AR it needs to meet the following conditions:

Materials

WebAR supports only the MeshStandardMaterial. 

While other materials can be used, only properties which are included inside the MeshStandardMaterial will be used within the AR view, leading to incorrect representation of the web view presentation of the product.

Lighting

Web AR uses the environment lighting of the physical world. Hence any lighting inside the showcase is not used within the AR.

This applies to both the Realtime light entities and baked lightmaps.
