Sildur’s Basic Shaders FAQ
10 questions players actually ask, answered.
How do I enable the shader after installing it?
Open Options > Video Settings > Shaders, then locate and select Sildur's Basic Shaders from your shader folder. Click Apply and the shader will activate immediately in your world.
Why is my game running slowly with this shader?
Check your shader settings for shadow quality and render distance—lowering these will improve performance. If you're on integrated graphics, reduce shadow distance further or disable shadow filtering in the shader options.
Can I use this shader with other mods?
Yes, Sildur's Basic Shaders works with most mods, but mods that heavily modify lighting or add custom blocks may cause visual conflicts. Test with your mod list to confirm compatibility.
Why do shadows look blocky or pixelated?
This is normal at default shadow settings on lower-end GPUs. Increase shadow map resolution in the shader options if your GPU can handle it, or accept the trade-off for better performance.
How do I make caves and underground areas brighter?
Open the shader settings and look for ambient lighting or cave brightness options, then increase the value. You can also adjust the overall brightness slider to affect darker areas without changing outdoor lighting.
Does this shader work with Optifine?
No, shaders require either Iris (for Fabric) or the shader mod loader compatible with your Minecraft version—they don't work alongside Optifine's shader system.
Why do water and rain look different than vanilla?
Sildur's Basic enhances water reflections and weather effects as part of its lighting overhaul. If you prefer vanilla water, check the shader settings for a water quality or reflection toggle.
Can I adjust how bright the sun and moon are?
Yes, most shader settings include exposure or brightness controls that affect celestial lighting. You can fine-tune these in the shader options menu to match your preference.
What should I do if I see strange colors or visual glitches?
First, try toggling shadow filtering or temporal anti-aliasing off in the shader settings. If problems persist, update your GPU drivers or try lowering shadow quality and render distance.
Is this shader better for old computers than other shader packs?
Yes, Sildur's Basic is specifically designed to be lightweight and runs well on older GPUs while still providing noticeable visual improvements over vanilla lighting.
