I chose to do away with the surface convention primarily because of my physics system. Because there is one physics body per entity, you cannot have physical material attributes like friction unless there is only one material applied to the entity. I also found in the course of development that the multisurface convention lead to a lot of headaches.
For materials I simply included a string for external material files. I thought about including a materials structure, but every system is going to be so different, and most engine store material files externally. Maybe a basic material structure can be included, and the file can either reference an external material or a material within the file itself.
