I strongly think that one of the reasons for the success of games like Quake are those fantastic BSP tools(where there is a 100% focus on gameplay elements, and not 100% graphics like today’s engines are pushing)…so why not try to incorporate or surpass them? I bet it would take less than a month for Epic to redo the entire BSP system… Static mesh support is easy, we’ve had it for years…but Unreal’s BSP system/tools have practically not changed since the beginning, and the only alternative we currently have for more advanced “BSP” shaping is to spend time and/or money learning/buying some external program(s) and import the un-editable results as meshes. The more integration, the better.
