A while ago, I noticed something with most space simulators. I could see the polygon edges of the planets. For some reason, this bugged me, so I opened up Blender to try a different way to deal with this problem. The result? Plane-t.
The only image that should be packed is the normal. I decided to not include the displacement because the warp was doing some strange stuff. Then again, the warp could fix the texture issue. Layers two and three should have a plane and half a sphere for recreating the displacement texture.
