    I have a mesh in my scene that is basically a voxel grid with marching cubes algorithm thrown at it, and for some reason like just decided to go trough some of the seams:

    It's very weird and I just can't fix it

    Is there any baked lights? If so, try to use "Directional" light maps instead of "Directional Specular".

    Nope, it's procedurally generated, so I didn't add baked lights

    Try set your light's normal bias to 0.0

    Sorry for not answering to this thread, I was really busy
    Problem is, that with a normal bias of 0.0 moiré patterns start to show

    EDIT:
    For some reason it's gone, thank you

    That moire pattern is shadow acne. You have to increase the light bias when you set the normal bias to zero. It might also show more or less depending on the shadow resolution and cascade.
