[Download] SEUS PTGI E7.1 Release! (Patreon)

[MINOR UPDATE] PTGI E7.1:

Magma blocks now emit GI 

Fixed RTX graphics card visual bugs

Fixed redstone torches on walls (in Minecraft 1.13 or later) not emitting GI

SEUS PTGI E7 is here! I would like to apologize for the delayed release. Uprooting all the old, stagnant code and replacing it with new systems without breaking things was more difficult than I expected, and a few times this process caused some befuddling bugs that took frustratingly long to fix. Other developers will know the feeling, sometimes during this process you can miss one little thing and it can send you on a hunt that lasts days. 

I know some of you are upset about how long it took, and some of you even feel that it seems like I'm artificially delaying releases to "milk" money. All I can do is try my best to assure you that I am not doing this. Anyone who has been following my work for a longer period of time (before I launched my Patreon page) will know that these delays just sometimes happen. Actually, since starting my Patreon page, I work harder and release updates way more frequently that I ever did before!

I know that many of you are here to support the development of SEUS and are understanding of these kinds of situations, and I am incredibly thankful for that! For those who are just here to get access, I would like to kindly say that if you feel that I am not earning your patronage, you can cancel and re-join at any time. I've kept "charge up-front" disabled for this reason.

SEUS has been something I've been working on for over 7 years, and most of those years I've earned almost nothing from it, at times putting in full-time hours or more just for the passion of it. I want to assure you that this is still a passion-driven project! With your support, we can continue to push the boundaries of real-time graphics in Minecraft! 

Thank you for taking the time to read this and for your understanding!

Okay, okay, so what's new in E7? Well, as I said in my last dev news post, the focus of E7 was mainly optimization, bug fixes and compatibility improvements, but there are some new features as well! Here's the changelog:

Minecraft 1.13 support!

Fixed yellow/green tinted lighting bug!

Performance improvements

Fixed low-light GI artifacts, improved GI color precision

Improved reflection noise filter: reduced reflections flickering and "blobby noise"

Fixed hue shifting at edges of ray traced reflection bright "lobe" areas

GI secondary bounces are more correct intensity. White/bright rooms look better

Entities (and entity armor), items, particles, and the player hand all have full specular + normal map support and render the same way as blocks in the world! 

Normal maps should now always display correctly, even on rotated blocks

Nether portals now render like stained glass instead of weird invisible water

New lightweight sky model (still work-in-progress)

Fixed redstone torches not visible in ray traced reflections

Improved screen-space reflections (may be more expensive, still rough)

Fixed weird reflection bug near GI render distance boundary

Improved GI filter, now preserves light across distance better. Still working on this

Surfaces lit with indirect light inside reflections should now look more similar in color/intensity to how they appear directly

SEUS Tonemap is now the default tonemap operator

Other small lighting tweaks

I hope it has been worth the wait! I'm particularly excited about the possibility of normal and specular maps on items and entities. I can't wait to see what you talented texture artists can do with this!

As always, I'm looking forward to hearing your feedback and seeing your screenshots in the Discord server!

PLEASE READ THE FOLLWING REQUIREMENTS FOR USING THIS SHADER PACK!

Minecraft 1.12.2 or 1.13.2 (no 1.14 support yet)

For Minecraft 1.12.2: OptiFine 1.12.2 HD U E2 or newer

Resource packs with custom block models may cause issues

Some of the currently known issues are as follows:

"Disco Floor" flickering artifact mostly seen in reflections (the new Secondary GI Samples option can help with this)

Secondary GI bounces (2nd bounce and onward) can take a while to adapt to lighting changes

Blocks which are not a full-sized cube in the world aren't considered properly in lighting and reflections (causes artifacts with half slabs, stairs, and the like)

Issues with the rendering of semi-transparent/translucent materials 

AN IMPORTANT NOTE ON GRAPHICS DRIVER ISSUES AND GPU COMPATIBILITY:

Since different GPUs can compile shaders differently than others, you may experience compile errors (causes "[Shaders] Error: Invalid program..." messages to appear in the in-game chat). 

If you experience compile errors, you can help me fix them by following the steps on this page, in the "How to Report a Compile Error" drop-down section and sending me the log!

Compatibility with AMD GPUs is not possible at the moment!

Compatibility with Intel GPUs is not possible at all!
