Vulkanic Light Engine Mod FAQ

10 questions players actually ask, answered.

How do I enable Vulkan rendering for this mod?
Open Video Settings from the main menu, find and enable the "Prefer Vulkan (Experimental)" option, then restart your game. Minecraft will boot using the Vulkan backend instead of OpenGL.
Do I need to download special shader packs or can I use my existing ones?
You can use your existing OptiFine-format shader packs directly—just place the zip files in your shaderpacks folder as usual. The mod translates the GLSL code to Vulkan automatically when the game starts.
What is FSR and how do I use it?
FSR (FidelityFX Super Resolution) is an upscaling feature that boosts your frame rate by rendering at a lower resolution and scaling up the image. Adjust the FSR Render Scale slider in Video Settings between 25 and 100 percent; lower values give higher frame rates but softer visuals.
Why are blocks and mobs disappearing when I use Chloride with this mod?
Chloride's entity and block distance culling features conflict with Vulkanic Light Engine. Turn off Fast Chests, Fast Beds, Max Entity Distance, Max Monster Distance, and Max Block Entity Distance in Chloride's settings to fix this.
Can I use this mod with Distant Horizons?
Yes, Vulkanic Light Engine works alongside Distant Horizons to render distant terrain with custom shader lighting applied to both the main view and far terrain.
Why does my UI and chat text look blurry?
The mod keeps your interface, chat, and debug screens sharp by rendering them at full resolution even when FSR upscaling is active, so blurriness in these elements usually indicates a different issue—check your shader pack settings.
Which shader packs have been tested and confirmed to work?
Complementary Unbound and Reimagined with Euphoria Patches, BSL Shaders, Bliss Shaders, Mellow, and Body Camera shaders have been tested with this mod.
Do I need to restart the game after changing the FSR slider?
No, you can adjust the FSR Render Scale slider in Video Settings and see the changes take effect immediately without restarting.
What happens if my shader pack doesn't work with Vulkan?
If a shader pack fails to translate or causes crashes, try disabling Vulkan rendering and using OpenGL instead, or check if the shader pack is compatible with OptiFine's standard format.
Will using FSR upscaling make my game look worse?
FSR upscaling trades some visual sharpness for better frame rates; at higher scales (75–100 percent) the difference is minimal, but at lower scales (25–50 percent) you may notice softer details depending on your shader pack.
