Sorry, I’m new to this site and I apologize for my bad English, but I would like to give some advice regarding forge on halo 4.

Can 343 implement that you can change the material of various objects used in in halo 4? Such as transforming the material of a ramp and convert it into wood, stone or other materials. And that this option would be available to all building blocks.
Something like changing the color of a block in the halo reach forge.
