SEUS PTGI HRR Reforged

About

SEUS PTGI HRR 2.1 Reforged is a community made edit of Sonic Ether's SEUS PTGI HRR 2.1, focused on improving image quality and performance, adding more configuration options, fixing visual issues, and bringing in selected features from Photon alongside original features developed specifically for Reforged.

Reforged is built around the original SEUS PTGI HRR 2.1 shader. It is not a shader made from scratch. The original SEUS shader provides the foundation, with selected Photon features and my own features and improvements added on top of it.

SEUS PTGI HRR 2.1 Reforged is an unofficial community edit. It is not affiliated with or endorsed by Sonic Ether. The original SEUS and Photon shader files are not redistributed by the patcher. You provide the required files yourself, and the patcher only works with the copies on your system.

Non-Commercial Project

This project is made for the Minecraft shader community and is not intended to generate profit.

SEUS PTGI HRR 2.1 remains the work of Sonic Ether. Photon remains the work of its respective developers.

Installation

1. Install OptiFine HD U G5+ or Iris.
2. Download the SEUS PTGI HRR 2.1 Reforged from this repository.
3. Download the original SEUS PTGI HRR 2.1 from Patreon, Bliss v2.1.2 from Modrinth and Photon v1.3b from Modrinth.
4. Extract the SEUS PTGI HRR 2.1 Reforged ZIP.
5. Once you have downloaded the required shader files, you can double-click Apply Patch.bat without manually dragging the shaders onto it.
6. The patcher will automatically search for the SEUS PTGI HRR 2.1 and Photon v1.3b shader ZIPs in common locations, such as your Downloads folder and Desktop.
7. If you have downloaded the same shader multiple times, Windows may automatically add (1), (2), etc. to the filename. For example, the file may be named SEUS PTGI HRR 2.1 (1).zip. If this happens, remove the (1) (or any other number in parentheses) from the filename so that it is named SEUS PTGI HRR 2.1.zip. Otherwise, the automatic file search may not recognize it.
8. If the patcher finds both shaders, it will automatically use them to generate your final SEUS PTGI HRR 2.1 Reforged shader pack.
9. The patcher will then ask whether you want to automatically install the generated shader into your shaderpacks folder. Enter Y for Yes or N for No. You can also simply press Enter to use the default option and automatically add the generated shader to your shaderpacks folder.
10. If the patcher cannot find one or both shader files, make sure the filenames are correct and place them somewhere the patcher can find them, then run Apply Patch.bat again.

Integrity and Verification

The patcher performs several checks before and during the patching process to make sure the shader files are not modified or corrupted.

The clean SEUS PTGI HRR 2.1 pack, Bliss v2.1.2 and Photon v1.3b are both verified using SHA-256 before patching begins.

The original SEUS and Photon shader files are not redistributed by the patcher. You provide the required files yourself, and the patcher only works with the copies on your system.

Every file that is patched is also checksummed both before and after patching. This allows the patcher to verify that the expected changes were made and that the resulting file is correct.

If all checks pass, the patcher can finish normally and the resulting files are verified byte-for-byte against what the patcher expects.

If any verification check fails, nothing is written. The patcher will stop instead of producing a potentially corrupted or incomplete shader pack.

This is intended to make the patching process predictable and prevent the patcher from silently producing an incorrect result.

Requirements

Minecraft

• Minecraft 1.16.4 or newer
• OptiFine HD U G5+ or Iris

Hardware

Component	Recommendation
Minimum GPU	NVIDIA RTX 2050
Recommended GPU	NVIDIA RTX 3060

These are general recommendations rather than strict requirements. Actual performance depends on resolution, Minecraft settings, view distance, shader settings, and the rest of the system.
