[WIP] Feature/port seteron magic

[joaoburatto]

Summary

Ports Seteron's lighting and visual updates from the outdated branch.

This doesn't configure or enable SSRT by default, as its a weird post processing, has a bunch of artifacts and might be outdated by current day standards. I instead left AO enabled on the post processing stuff.

Updates the lights to be more appropriate with the new deferred rendering and material updates, also changes the scene lighting to full darkness contrary to full brightness as it was before.

Also moved the global post processing layer to a separate gameobject child to the camera for organization sake.

Fixes the ministation map to work with the new system.

PR checklist

What do you want to add to the GitBook?

Should add a page in Design explaining what the the lighting should look like and why. (soft lighting so no hard shadows, etc) And a page in systems explaining anything important regarding the implementation.

I'm adding @Seteron remarks from discord here, so another reviewer can check if those are correct :

• The player camera's post processing volume got deleted, meaning it's recieving no post-processing
• The old stuff was all designed for Linear color space but the current project is on gamma, so it doesn't work right
• The old branch was using the half-toon shader I think, not the full one.
• The cgincs aren't working correctly
• The light fixture values aren't correct
• The player's skin is using some kind of emissive shader?
• Ambient lighting is enabled, so everything is way too bright

Here is a reference for around what it should look like with correct settings

With shadows:
