Baking to Low Poly

Blender can generate bump/height maps and normal maps.

Baking the normals of a sphere onto a flat plane.

1. Select your high-res source object(s) and your low-res target object. The target object must be Blender's active object and must be unwrapped.
2. Go to the Bake panel and enable Selected to Active. This activates two settings:
   • Distance defines how many Blender Units away a source object's surface can be from the bake camera. 0 means "no limit".
   • Bias raises the bake camera above the target object's surface. If your source geometry overlaps both above and below the target object, consider raising this until the bake camera is always "looking down". Otherwise you will probably see artefacts.
3. Select the appropriate Bake Mode:
   • Normals to generate a normal map.
   • Displacement to generate a bump/height map.
4. Bake!
