Forget-me-not Shaders

Forget-me-not is a semi-realistic pipeline shader for the Canvas mod. It's designed to give the most authentic and immersive experience while sticking to "traditional" rendering methods to keep up good performance.

Canvas is a client-side renderer mod that uses shaders for advanced rendering with the goal of having a modern and very flexible design for high performance and better readability. The shader system is entirely different from Optifine and Iris & Sodium and as such, Forget-me-not won't work with any of these mods! See the how to use section for installation instructions.

If you're a developer or mod hoster, Forget-me-not is licensed under the LGPL v3.0, so please make sure to read over the terms of the LGPL if you use any of Forget-me-not's original code or distribute it.

how to use third-party shaders with canvas

Be sure you're on 1.19.4 or above. Support is not guaranteed for versions that Canvas doesn't actively support.
Install Fabric.
Get Canvas Renderer mod through Modrinth. Keep in mind that Canvas does not work with Sodium, Iris, OptiFine, or OptiFabric.
Download your preferred pipeline shaderpack. If you're looking for alternatives to Forget-me-not, try out Lumi Lights, Lomo (not for gameplay as of this writing), or Aerie (vanilla-plus, wip).
Launch your game, put your downloaded .zip file into your resourcepacks folder and activate the resource pack. (Don't extract it!)
Navigate to Options / Video Settings / Canvas / Pipeline Options / Pipelines and select the pipeline that you want to play with.

troubleshooting

Experiencing bad shadow outcomes? In Options / Video Settings / Canvas / Debug, set Shadow Priming Strategy to TIERED and Disable Shadow Self-Occlusion to true.
Does Canvas say in chat that some shaders are broken? Please grab your log in .minecraft/logs/latest.log and all contents of the .minecraft/canvas_shader_debug/ folder and either make an issue on GitHub or let me know about it on Discord.
Does every Canvas pipeline break other than Canvas Basic? If so, your device is probably incompatible with Fabulous graphics, which most Canvas pipelines use. Unfortunately, there's no fix for this.
