SEUS PTGI E1 is here! (Patreon)

Hey, everyone!

So, here comes the first experimental version of SEUS with path-traced global illumination!

PLEASE, READ THIS POST!

This is an extremely early development version with many known issues and isn't suitable for standard gameplay. 

Here are the requirements for running this shaderpack:

OptiFine 1.12.2 HD U D1 or newer

Options > Video Settings > Details > Alternate Blocks: OFF

Options > Video Settings > Natural Textures: OFF

Options > Video Settings > Shaders > Shadow Quality: 1x

Options > Video Settings > Shaders > Old Lighting: DEFAULT

Options > Video Settings > Shaders > Normal Map: OFF

A resource pack with NO CUSTOM BLOCK MODELS

Most significant known issues:

Only soft lighting from sky (no typical sunlight shadows)

Only glowstone, lapis lazuli, and redstone cast light into the scene (the latter two to demonstrate colored lighting)

Unloaded chunks don't contribute to lighting

Many block types are not stored in voxel volume (torches, grass, etc.)

Lighting assumes every block is a perfect cube, which causes lighting issues with slabs, doors, stairs, etc.

Transparent blocks are not rendered currently (water, stained glass, etc.)

No exposure compensation

Lighting on hand is strange while moving

Lighting on mobs is strange when they move

This is based on a much older branch of SEUS, so many configurable options are missing

Light leaking in larged closed-spaces

A high resolution detailed resource pack is recommended to hide some of the lighting artifacts (I recommend the old version of LB Photo Realism, as seen above).

There's still a lot of work to do, and I've got plans for optimization which should bring a significant performance improvement.

Let me know what you think!
