I am making a map with some fairly steep ladders and cables that I would want to be scalable. Can I alter the slope incline value or is it hard-coded into the world? 
I'm actually quite surprised how stingy it is, in like HL2 it requires quite a huge incline to actually cause you to stop being able to scale up it.
