I'm working on optimizing one of my current projects at the moment and am trying to figure out what a good height for my skybox. This current project has some high buildings and I'm attempting to figure out a good height to transition between them in the main geometry and their higher points in a skybox. My questions are these. What is the highest a soldier can rocket jump? What is the highest a demoman can stickybomb jump? Should I care about the highest a engie can turret jump? I know players don't like to hit their heads on Skyboxes while making high jumps. Any information on this would be helpful. Depending on these answers will help me determine if this is an ideal solution for optomization for this particular project.
