SEUS PTGI E5 is here! This update isn't as big as the last, but some new features that aim to enhance your gameplay experience are here.
E4 was the first version of SEUS PTGI that I actually tried survival gameplay with, and it led to some insights. The most distracting problem for me was how long lighting takes to update, and all of the ugly artifacts that this can cause (you'll know what I'm ...

SEUS PTGI E4 is finally here! Sorry for the wait! But, I think it'll be worth it, this one's a big one.
My goal with this update was to take the first steps in getting SEUS PTGI ready for gameplay. Many effects have been fixed and added from the main version of SEUS, though, the main focus of this update was getting world-space ray traced reflections in. What's Minecraft without water, what's w...

Exciting news about SEUS PTGI!
So, first of all, I've gotten sunlight with proper GI contribution working with path traced GI! I also was able to optimize the inner path tracing code, so optimized path tracing + sunlight contribution ended up actual...

Inspired by all the shiny new RTX stuff, I've been working more on SEUS PTGI and want to share my progress.
If you're a Gold patron, you've probably tested out SEUS PTGI E1, the first experimental version of SEUS with path-traced lighting. It was a good first attempt, but there were myriad problems that were visually unappealing and distracting.
SEUS PTGI E1 traced lighting at 1 sample-per-pixel at half-resolution for an effective 1/4 samples-per-pixel. You could argue that path-tr...

All-new volumetric clouds powerful enough to drive a new weather system are the focus of this new Experimental version of SEUS Renewed!
Of course, this is the first experimental version with a very bare-bones weather system. As of now, the biome the player is in does not affect weather; this is being worked on.
My favorite emergent effect from this is sunshowers--a rare moment of sunshine...

Hey, all!
The first experimental version of SEUS with LPVGI (Light Propagation Volume Global Illumination) is here!
LPVGI in SEUS has the power to totally replace Minecraft's lighting and allows infinite bounced lighting from all light types with correct occlusion!
Of course, working within the limitations of OptiFine has made implementing it quite challenging. Don't expect a playabl...

It's finally time for the first experimental release of the main branch of SEUS!

A LOT has changed, but these are the most noteworthy changes:
- Leaf subsurface scattering
- Land atmospheric scattering matches sky model
- Fixed POM and normal mapping on rotated textures/blocks
- Fixed black objects (like on custom furniture in mods)
- Added custom noise text...

I know there are only three of you guys right now, but I'd like to poll you guys on some work-in-progress feature projects, and some ones I haven't begun working on yet.
I'm curious as to which prospective features you're interested in most!

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 newe...

Just wanted to post the video here, in case you guys missed it. I put together a quick video showcasing the new path-traced global illumination. An experimental version of SEUS with this tech will be released soon!

Hey everyone. I wanted to let you know that a close family member of mine passed away, so I probably won't be too active or terribly useful with SEUS development for a little while. I'm letting you guys know so you don't have to wonder what happened if I'm inactive for a while. Thanks for understanding.

So, you guys might remember me talking about how I was able to store block data in a volume texture, even off-screen blocks. Basically, I created a way to store all blocks in the scene (that are touching air or are within a certain distance).
This exciting new development opens up a whole new world of possibilities! Among those, and the most advanced of them all, is path-traced GI--a way of gathering light bounces by tracing and bouncing rays through the scene.
Those of you who a...

So, what's next? The first thing I'll work on is moving to a proper deferred + forward pipeline for better handling of transparent rendering. This will fix issues with transparent materials and free up the internal data structure a bit, which will likely improve performance.
Biome-specific features are now possible thanks to the new "custom uniforms" feature of OptiFine! I'll be delving into that as well.
I've got plans to redesign and integrate volumetric clouds and crepuscular r...

We're so close to the first 1.0 release! Yes, there are still minor bugs to fix, but I don't want to delay the release of SEUS Renewed 1.0 any further. Of course, SEUS Renewed will continue to be improved past the first release. If nothing is terribly wrong with this version, then it's straight off to SEUS Renewed 1.0!
Changelog:
- Added End shaders
- Updated Nether shaders to SEUS R...

Here it is, the first beta version of SEUS Renewed!
There's still some optimization I'd like to do, so keep that in mind! You can provide feedback either in the comments here, or in the SEUS Discord server.
In the Shaders screen, make sure "Old Lighting" is set to "Default"! More shader-specific options will be added soon.
Looking forward to your feedback!
