(A) Here we see the problem on the finished texture in game.

(B) This is the same section but in the edit panel, gone.

(C) This is the same mesh with the texture entirely turned off eg. WorldGridMaterial

So where is (A) & (C) this coming from, and how can I stamp out the reason so I can get something more resembling (B)

Additional Information:
The effect appears to vanish when ‘unlit’ mode is enabled in the editor.

We’re facing the exact same issue… did you find a solution by chance?

This is shadow acne, typically caused by inadequate shadow bias (setting in your light)

Can also happen if you make your attenuation radius too large.
