Smoothing across multiple objects I am trying to manually create a fragmented spherical object in Blender for use in a Unity game. When i create a separate object from the mesh the smoothing is no longer contiguous so it becomes obvious that the object is already fragmented.

Is there a way for the fragments to appear like the original whole and contiguous unbroken sphere with no gaps and consistent shading? Can I instruct Blender to smooth across all objects instead of smoothing individual fragments?

I am quite new to modeling and would appreciate any pointers.

Thanks!
Yes, this can be done.


keep a single whole object(this is the reference for correct normals).
enable auto-smooth on all broken parts(needed for custom normals to show).
using the Normal Edit modifier on the broken parts to copy the normals from the whole object to the broken parts.


If you want to avoid some slow-downs from continued updates, you can apply the modifiers to store the custom normals.
