The lower the polygon count, the better the performance of the shader will be. | * Use low-poly models at all times.

| For this particular model, to ensure it will work with XFur Mobile without any issues, we set the rotation of the mesh (called Racoon Body LOD3) to be 0,0,0 instead of its original value of -90,0,0. We also set the Root Bone in the Skinned Mesh Renderer component to be the Raccoon Realistic root object instead of the Pelvis transform that it has assigned originally. This does not affect the animations in any way, but allows us to recalculate the normals in a more accurate way internally, which is necessary for XFur Mobile to use the more advanced features such as snow coverage. | For this particular model, to ensure it will work with XFur Mobile without any issues, we set the rotation of the mesh (called Racoon Body LOD3) to be 0,0,0 instead of its original value of -90,0,0.
