[Compatibility]

[benfederal]

Prerequisites

• I have tested with only the conflicting mods + VulkanMod + VulkanMod Extra
• I have verified this works without VulkanMod Extra installed
• I have checked that all mods are using compatible versions
• I have searched for existing compatibility reports

Compatibility Issue Type

Mod Conflict (crashes, errors with other mods)

Conflicting Mod(s)

Primary conflicting mod:

Mod Name: Color Saturation

Mod Version: 1.0.0

Mod Source: Local Development

Mod Link: Private project

Additional conflicting mods (if any):

Mod Name: VulkanMod

Mod Version: Latest

Related mods that might be relevant:

Sodium

Issue Description

What exactly happens when both mods are installed?
My mod, "Color Saturation," which utilizes PostEffectProcessor to apply screen-space color filters (Saturation, Hue, Contrast), fails to render or initialize its effects when VulkanMod is active. It works perfectly with Sodium/OpenGL.

What should happen instead?
The mod should ideally be able to hook into the Vulkan rendering pipeline to apply these adjustments, or at least provide a graceful fallback/warning for the user.

Are there any error messages or crashes?
No hard crash, but the effects are completely bypassed/ignored by the Vulkan rendering pipeline.

Does the issue affect specific features or general functionality?
It specifically affects all post-processing color adjustments provided by the Color Saturation mod.

Steps to Reproduce

Install Fabric Loader, Sodium, VulkanMod, VulkanMod Extra, and Color Saturation.

Start Minecraft and load any world.

Observe the screen output; color saturation/contrast filters from the Color Saturation mod are not applied.

Crash Logs/Error Messages

Expected Behavior

Both mods should ideally coexist.

The Color Saturation mod should either successfully hook into the rendering pipeline under Vulkan or provide a clear compatibility warning to the user.

Workarounds/Temporary Solutions

No response

Issue Severity

Critical - Complete incompatibility, crashes, or data loss

Testing Scenarios

• Fresh Minecraft instance with only required mods
• Different mod versions (if available)
• Different VulkanMod Extra configuration settings
• Both single-player and multiplayer (if applicable)

Hey, thanks for checking this out. Do you have a Discord server or a preferred way to discuss this? I'd love to chat about the rendering pipeline and see if there's a way to get my mod working with VulkanMod. (Discord)

Hello there! I don't have a discord server and also haven't been maintaining this project for a while since Mojang added Vulkan renderer support in 26.1 snapshots. About your issue: you'd need to get VulkanMod source (Xcollateral is the developer, I'm not) and check it instead. You should be able to hook your mod to SSO part of VulkanMod (I'm not really sure though) and it should theoretically work.
