CryEngine 3 Blocking out

Just using solids in CryEngine 3 to try and get a feel for scale a space of the level. The great thing with CryEngine 3 is that I can quickly generate trhings play it and go back to editing in real time so what you see is what you get. This has saved a lot of time in having to build lighting everytime I make a small change. When I used UDK I often found that frustrating and time consuming though I am missing the material editor there, but I'm sure CryEngine 3 has a lot in store with materials from what I have seen with the tutorials I have been following!
