This is so that Maya knows which object the normals will be generated from as well as
what UVs to fit into on the lower-resolution mesh.
1. Select the HighRes model, and set the Translate X attribute back to 0 .
2. Using the Outliner, select the HighRes model. Then, holding Shift, select the
LowRes model.
3. Switch to the Rendering menu set, and go to Lighting/Shading > Transfer Surface
