being able to override the default shaders

@NathanMikeska it would be to try and make glass, then it's mostly atmosphere and water especially for the planet packs. But then also I don't really know how shaders work in sr2 and what's more or less difficult

Obviously the more stuff that can be overridden, the better, but was there anything specific you were wanting to accomplish with this? Custom terrain, or parts, or atmosphere... other stuff?
