SEUS PTGI [E12] 1.20.4 → 1.20

SEUS PTGI (Path Tracing Global Illumination) is a highly advanced shader pack for Minecraft, utilizing path tracing technology to create stunning visuals with realistic lighting, shadows, reflections, and global illumination effects.

SEUS PTGI 1.20.4 → 1.20 [E12] may still be in its alpha stage. Still, rumors are already going around that it is one of the most highly valuable Shaders in the Minecraft community. Due to the name that Minecraft has made over the years, expectations are pretty high. This is because people see it as a platform for bringing their imaginations into reality. For instance, you can create a world and make it look exactly the way you want. Unlike most games you have explored in the past, Minecraft offers lots of freedom and flexibility in creativity. The problem is that despite all of such creativity and popularity, Minecraft as a game can sometimes be very dull to explore. This is due to its graphics, which many players have criticized in the past. In addition, its default visuals and graphics seem to have fallen short of the required standard as the struggle to get an immersive experience seems elusive for most players.

You will need a robust and premium Shader pack tested and proven to deliver on its claims to overcome such a problem. This is where you will find SEUS PTGI Shaders to be very resourceful. If you don’t know, this is one shader pack that promises to bring players’ worlds into life. This post will be revealing some facts about SEUS PTGI E12 that you never knew till now. The aim is to see why it has to be downloaded once released into the Minecraft community. Do you want to get the best of your Minecraft adventure? Are you aware that improved and high-quality visuals have many roles to play for such to become a reality? This is what SEUS PTGI Shaders has been created to help players accomplish in the game. Just as said above; indeed, this shader pack is still currently being worked on, but the signs are undeniable that it can change your gaming experience for good. The brain behind this highly impactful mod is Cody, the developer of SEUS Shaders (Sonic Ether’s Unbelievable Shaders), one of the few shader packs that have managed to attain legendary status in Minecraft community. 

Of course, suppose you love what Sonic Ether’s Unbelievable Shaders have got to offer. In that case, this means you will appreciate the additions and features of SEUS PTGI Shaders. First, it should be noted that the PTGI is an acronym for Path Traced Global Illumination. This should explain more details about what the mod has been created for. Simply put, it is an upgraded version of SEUS. In other words, it tries to bring in those features that have been lacking in SEUS. It can be said that the significant strength of SEUS PTGI Shaders is the ray-tracing effects that it brings. With this feature, your world will have much better and improved shadows as well as reflections. This will further translate into your world looking more natural than before. Furthermore, it has managed to bring in ray tracing shader of very high quality. Although this feature is rare, modern technologies are beginning to make Minecraft players experience it in their respective worlds. 

There is one thing you must expect after having this shader pack installed. This is a massive improvement in your game’s visuals. The reason for this is quite simple – it has met the expectations of the Minecraft community. Imagine having a world where all the necessary effects are present. These could be shadows, highlights, and reflections. Its creator deserves some credits for coming up with such a huge feature that Minecraft has been missing for years. Please note that because this mod isn’t available in the Minecraft community, for now, you can only test out its feature by making some contribution. However, it will become available for free download and installation once the developer (Cody) has decided it should be released. The truth about SEUS PTGI Shaders 1.17.1 is that it is one shader pack that Minecraft has lacked for years. Although different shaders have been released in the past, none addressed this problem.  

At the moment, SEUS PTGI Shaders doesn’t have any compatibility issues. It can be used alongside GLSL shaders and OptiFine. Also, it can work on different types of NVIDIA graphics cards. However, please note that if your card is low, the shaders may struggle to deliver optimum performance. As of now, it doesn’t have AMD compatibility. Also, an RTX graphics card isn’t required to work after being installed on your PC.


📷 Gallery🔧 Info📝 Changelog
  • Minecraft 1.18.1 (older version compatibility may be present but is not guaranteed)
  • OptiFine HD U H4 or newer
    • Options > Video Settings > Details > Trees: Fancy or Fast (Smart may break lighting)
    • Options > Video Settings > Quality > Natural Textures: OFF
    • Options > Video Settings > Shaders > Shadow Quality: 1x
    • Options > Video Settings > Shaders > Old Lighting : DEFAULT
  • Resource packs with custom block models will probably cause lighting glitches!!!!!!
Known Issues
  • Particles aren’t rendered properly yet
  • Block texture alpha is not considered in diffuse GI tracing, so doors and trapdoors don’t let any light through their windows currently.
  • Being underwater in ravines/caves shows light leaking, and “glowing” water fog. This is unavoidable currently.
  • “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
  • Issues with the rendering of semi-transparent/translucent materials
  • Lighting breaks often when using resource packs with custom models, a solution is being investigated!

HRR 3 by SonicEther

  • Atmosphere, cloud, and outdoor lighting improvements: white balance adjustment to make sky bluer and sunlight less dingy, decreased cloud coverage directly overhead and increased coverage in the distance near the horizon, balanced cloud and sky colors so that ambient shadows aren’t pale and washed out anymore when Clouds in GI is enabled
  • All blocks in 1.18.1 function properly, including new light sources: candles, glow lichen, and glow berries
  • Candle lighting is based on the colors in the candle texture itself and how many candles are in a block
  • Sea pickles and end rods now emit light
  • GI denoising filter improvements
  • Reworked default tonemapping for an emphasis on a bright, vibrant look
  • Increased GI voxel data area size, allowing greater view distance for ray tracing effects
  • Increased default diffuse and reflection ray lengths to accommodate 1.18’s larger caves and world structures
  • Improved “HRR” tech: fixed blurring when quickly moving the view, improved stability and responsiveness, improved “Filmic” pixel look setting
  • Entities now have proper motion vectors and don’t look awful under motion and contribute properly to motion blur!
  • Default water fog density is now 0, avoiding glowing water issues. You can turn it back on if you miss it!
  • Smoother bloom
  • Fixed bug seen in the shading of blocks inside smooth reflections
  • General cleanup for shader options
  • Changed default torchlight color temperature 
  • Added new option: Lighting > Candlelight Color Temp
  • Added new option: Lighting > Light Leak Fix. This replaces the old light leak fix options previously found in Raytracing settings. This has been reworked/improved to not be based on where the player is, so moving in and out of caves no longer awkwardly enables/disables light leaking. 
  • Reworked Utility > Visualize Dangerous Light Level option. Considers that mobs now require light level 0 to spawn, and doesn’t look blinding and horrible anymore
  • Added new option: Surface > Texture LOD Bias. Higher values increase detail in textures but can lead to instability, ghosting, and reduced performance. Lower values improve image stability and performance but can lead to lower resolution textures at distance and grazing angles
  • Added new option: Surface > Anisotropic LOD Bias. Enabled by default. When enabled, preserves details on surfaces at higher grazing angles. Similar tradoffs as Texture LOD Bias.
  • Added new option: Surface > Wet Caves Effect. Disabled by default. An experimental effect that attempts to make surfaces inside caves damp/wet.
  • Added Raytracing > GI Responsiveness option. High responsiveness allows lighting to respond to changes more rapidly but can cause instability and decreased detail. Low responsiveness allows more samples to accumulate over time and offers increased detail and stability but causes laggy lighting.
  • Fixed crazy bloom when in lava
  • Fixed caustics bugs
  • Added short raytraced contact shadows
  • Fixed certain flowing lava shapes not being voxelized or contributing to lighting
  • New physically-inspired low-light vision effect which now applies on top of the entire image instead of fakely on certain light types and improves the look of night scenes
  • Moonlight overhaul: the moon phase now properly affects night time lighting, being fairly bright during the full moon and very dark during new moon. 
  • Moon and moonlight color tweak
  • Starlight contribution to GI at night, providing some visibility even when the sky is very dark at night when the moon is at its darkest phase
  • Increased max ray distance for Atmospheric Godrays
  • Improved energy conservation in reflection filter. Rougher surfaces now show more subtle reflections more visibly
