Do you really expect people to read that?

How about a summary of what you posted

Aint nobody got time for that

I've used sketchup for many years and im still waiting for a way to organize materials.
the company that i work for usually does big buildings, and the number of materials within a scene can get rather large.
It really does become an issue also when you take models from another user that has zero consideration for the amount of materials used.
If we could simply group materials by stone, finish, building, etc it would make it sooooo much easier to navigate through them.

PLEAAASEEEEE, add this feature!
or if anyone knows of a plugin let me know

i've been wondering the same thing
hopefully vray will support that on its next release

HELP!
how do i install this plug-in if its not an rbz file?
im using sketchup pro 2014
