I am currently having this issue where 2D layers close to each other will create shadow artifacts that are unwanted, even z-tearing artifacts when no Z coordinate is the same.
Example 1: Shadow artifacts
Example 2: texture tearing
My assumption is that this happens when you place planes with Masked opacity on top of each other.

EDIT: Found what case 2 was, it was two layers overlapping collision, as seen below:
Is there any solution to this? I am having the same issue where I have two planes both with masked opacity and I seem to be unable to disable the contact shadows.
Turn “cast shadows” OFF on the actor details and see if it helps
It doesn’t. I’ve noticed the contact shadows are only in daylight, do you think it could be solved through some settings related to that?
There is also a setting to cast shadows on the material settings as well, try that too then look into recalculating normals and tangents in modelling mode, that sometimes fixes it too
