So, I imported the pyramid into Second Life to see how it presents itself and how it imports/exports. SL uses a right handed coordinate system (I think). The Z axis is going up and down. Scale and origin seem to be pretty dead on. The only issue I had really is something to be covered later I am sure. Currently the object is one so there are not any faces to texture within the game so - something to work on but for now-- Bring on the next lecture
