Описание: Using enhanced shaders and SSS as the baseline, I have improved the lightning, ambient, and ggx model to improve the visuals of stalker anomaly. As always, thank you Lvutner for answering any of my questions.

Improvements include:
Better looking guns.
Better looking flora.
Better looking assets and materials.
Better looking metallic objects.
Improved Fog.
Improved indoor lightning.
Major and minor changes to the pseudo pbr model.
