OMG, thank you so much, you have no idea how long I have struggled with this, if I wasn’t overjoyed I would feel great shame for missing that simple missing line of code. Was so sure the Draw method was fine that I never truly looked over it in fine detail nor did I rewrite it manually which would of relieved the mistake. The foreach draw calls were just artifacts of my hours of changing and chopping. you were right about never applying the effect to the mesh (part.Effect = shaderEffect;).
Thank you.
