Hi! I´m currently designing a tf2 level ambientated o a medieval castle (I know its not strict tf ambientation, but I think I can adapt it and mix both of two worlds) but I have a problem... I have two round towers with two floors each. I remember I once saw a tutorial here wich explained how to make (easily) round ramps and stair, and I´ve been looking for it. Does anyone have the link? Many thanks!
