Supplemental Patches

Supplemental Patches enables users to create custom shaders for modded blocks, entities, items, particles, etc, through a resource-pack. The mod by default, comes with a built-in resource pack with supports many popular mods.
These additional shaders are patched into Euphoria Patches, if it is installed.

Some of the most exciting features of the mod include (for players):
- Over 500 high-quality shaders for custom materials from a variety of popular mods (e.g. Supplementaries, Quark, Jaden's Nether Expansion). See full list here.
- A custom End nebula skybox based on Enderscape's End atmosphere
- A cool fog effect based on the effect from Doom and Gloom
- Fixes to shader issues for many mods (e.g. Endergetic Expansion, Upgrade Aquatic, Doom and Gloom)
- Fixed rendering of item shaders when displayed on block entities (e.g. Supplementaries Pedestals, Item Shelves)

FAQ
Q: Will there be ports to loaders other than (Neo)Forge and Fabric?
A: Probably not.
Q: Will there be backports?
A: Probably not.
Q: Can you support XXX mod?
A: All in due time. Alternatively, you could do it yourself. Have a look at this tutorial for more details.
Q: I found a bug.
A: Please report it to me first, do not bother the developers of Complementary Shaders / Euphoria Patches.
Q: The shaders I added aren't showing.
A: Try reloading the shaderpack, after ensuring that the resource-pack is loaded. Alternatively, check which layer the block is being rendered in using the Euphoria Companion mod. Certain blocks (e.g. certain glass blocks) may be rendered as cutouts rather than translucent blocks. You will need to change the layer they are rendered under using block.properties.json.
Q: The built-in shaders aren't working.
A: Similarly, try reloading the shaderpack and ensuring that the built-in resource-pack is loaded.
Q: Does this work with Optifine?
A: No. This only works with Oculus / Iris.
Q: Can I include this my modpack?
A: Yes, go ahead.
