Clear Sky - sharp rectangular shadow artefacts on AI

[argosurvivors]

Describe the bug
Sharp light artefacts are appearing on AI stalkers. This is due to shaders. Once I placed shaders from Stalker Anomaly this error was fixed, it became very subtle.

To Reproduce
Steps to reproduce the behavior:

1. Start the game
2. Approach any AI stalker during daylight and look at their clothes area to spot shadow artefacts

Expected behavior
Shadows should be less pronounced without sharp rectangular spots
