Shaders

Since the "Standard" shader of Unity's Built-in RP is designed for more realistic games, it doesn't look very good if you only apply a single low-res texture to it. We need a more "primitive" shader for this to look good.

Fortunately Unity ships with many more shaders, and after some tests i found two that are perfect for Redguard Unity:

Legacy Shaders/Diffuse

• For 99% of objects in the game. Looks identical to the original game.

Legacy Shaders/Self-Illumin/Diffuse

• This should be used for emissive elements, like lamps, or other light sources.
