Mapping the piston

- Time to unwrap our piston arm, so that it is ready for use in the texturing of normal map making parts of our pipeline. We can start by making sure only our low poly mesh is in the isolation mode and then move onto adding UVW map and unwrap UVW modifiers to the stack. And then, on the unwrap, coming to edit to object mode and click to select one of the horizontal edges on either the top or the bottom of our mesh. We can then use the loop command, which again, essentially splits our mesh in half and creates a two cluster set. Now, the arm section of the mesh, we want to unwrap like a cylinder. So, there is no need to have two seams. Holding down the alt key then, let's deselect the horizontal edge on the top of our model, which will leave the seam on the bottom, when we convert our selection over. In fact, let's come down to the peel rollout and do just that by clicking on the convert selection to seams button. We do want to separate the arm into its own cluster, so as to make the…
