Mesh object in awayjs-core

[officefish]

I try to play with examples but there was not entities package and Mesh object in awayjs-full build. What was the reason of that? Should I use several libraries awayjs? As far as I understand if we use prefabs it returns DisplayObject (even if it is a Mesh in private methods) that's why we can't set materials dynamicaly in runtime. But because of there no entities lib in awayjs-core we also can not transform DisplayObject to Mesh. So we have no ability to use all Mesh methods with prefabs generic instances.
