MC-68294Pixelated smooth lighting on 3D models
The top and bottom faces of extra polygons added to the block model have pixelated lighting/shading when placed directly next to the North or South of a wall. This doesn't happen when placing the block directly next to the East or West of a wall. This only occurs when smooth lighting is on.
Note: This block model has many polygons.
What I expected to happen was to perceive normal lighting like every other full block in Minecraft.
What actually happened was that the top and bottom faces showed a pixelated lighting/shading.
(For your ease I have narrowed down the models in the resource pack to those that are relevant.)
Steps to Reproduce:
1. Use the Resource pack containing the cobblestone.json block models attached to this bug report.
2. Place a cobblestone block or slab to the North or South of a 3-block heigh wall. (Or reproduce attached images)

Windows 8.1 running with Java 8 (build 1.8.0-b132)

To add to this... The issue is cause by the fact that each cuboid element of a model uses the smooth lighting algorithm of a full block, rather than using its own shape. This appears to be due to that algorithm being hard coded to the relative coordinates 0.0,0.0,0.0 an d 1.0,1.0,1.0. This is proof that smooth lighting needs a rework.
