A model can be an object or a set of objects with various attributes such as shape, light, sensor, ...
A model can handle vertex color if it has a shape attribute.
You can instantiate model in a scene just like you do in C++ with class.

You can import 3d assets as model or save object from a scene as model
In a scene :
Set a Model : assigns a Model to the object. Warning : any changes on the object will be lost. You can first register the object as a Model.
Change Model : changes the Reference Model of the object. Warning : any changes on the object will be lost. That is why it is better to work on a Model rather than an instance of Model.
Save Model as : Saves the selected object as the new Model. Warning, only alphanumeric characters and the underscore (_) are allowed for the name of the Model.
Unbind Model : detach the instance of a Model of its reference Model. This allows you to adjust the reference Model then update all the other instance.
Update Instance from Model : Apply all changes made on the Model to the object. Warning : any changes on the object will be lost.
Update Model from Instance : Apply all changes made on the item to its reference Model.
