Just wondering, does PC do anything to help combine and optimize the polygons of simple building elements at runtime? I see a lot of people building massive things out of hundreds, if not thousands of parts, each one being only 1 grid space in dimension maximum. What I notice is that, for example, one massive floor area that is a big rectangle could be all representing by one massive rectangular prism, even though it is comprised of many many individual square peices. The same could be applied to any simple rectangular prism shaped building element. My question is, does PC do this to help save performance?
