Trying to get both stickies and engineer buildings to work properly on dynamic map elements. If someone can explain this to me, I'd love to hear it. My phases were: a) func_brush - engineer works, stickies don't. I knew this going in. b) func_brush -> prop_dynamic with vphysics. Stickies work, engineer can't build. Makes no sense to me, I waste hours trying different configurations. c) func_brush -> prop_dynamic -> player clip. Stickies and buildings suddenly work. Each "layer" is separated by 1 hammer unit. Is there special code in the game that only allows engineers to build on props if there's a matching player clip?
