BSL Shaders
by CaptTatsu
One of the most popular and well-balanced shader packs. BSL offers beautiful visuals with good performance, making it an excellent all-around choice for most players.
What BSL Shaders looks like in-game
Read this set from the colour grading outward. Almost everything people recognise about BSL comes from how warm it renders sunlight, and the shadows, reflections and bloom below are all tuned to sit inside that warmth rather than to be noticed on their own. If you are comparing it against another pack, the volumetric lighting tile is the fairest place to start: it is the effect BSL spends the most of its medium-tier budget on.
BSL Shaders ships 8 headline effects. 8 of the 8 tiles below are cut from screenshots BSL Shaders publishes of itself, not drawn by us. For each effect we went through the pack's own gallery, found the frame where that effect is clearest, and cropped the part of it where the effect is actually happening. The uncropped frame heading this page comes from the same gallery and is left uncut, so any detail you see below can be put back into the scene it came from.
Shadows
Shadows fall long in the morning and shorten through the day, and BSL keeps their edges soft enough that they never look stencilled onto the ground.
Volumetric lighting
The air itself picks up light here, so a shaft coming through a gap in the canopy is something you can see rather than something you infer from the ground.
Reflections
Water, ice and polished blocks return the world above them, and BSL keeps the reflection warm rather than mirror-neutral so it matches the rest of its grading.
Bloom
Glowstone, lava and torches bleed a little light into the pixels around them, which is where BSL's reputation for warmth mostly comes from.
Motion blur
Sprinting and mine-cart rides smear between frames instead of stepping, which reads as speed in recorded footage more than it does in play.
What you see above is a real BSL frame, showing the terrain and lighting the effect works on. The movement itself only happens while the game is running, and no single frame can hold it.
Custom sky
The vanilla sky is replaced with BSL's own gradient, sun, moon and star field, tuned to hand off cleanly into its golden sunsets.
Waving plants
Grass, crops and leaves bend and spring back in a breeze that runs across the whole field rather than per-block, so a wheat farm moves as one thing.

Color grading
A warm, saturated grade sits over the entire frame. It is the first thing people notice about BSL and the first thing they turn down if it is too much.
Compatibility
What you need to run BSL Shaders
Baseline card: GTX 1050 / RX 560. Meters are scaled against a 12 GB VRAM / 32 GB RAM reference build.
An overview of BSL Shaders
BSL Shaders is the pack most people meet first, and that is not an accident of marketing. CaptTatsu built it around a defaults-first idea: the profile you get on installation is already the profile you are meant to look at, so there is no tuning session standing between you and the result. That decision has kept it near the top of every recommendation list for years.
Visually it goes for warmth. Sunlight comes in golden rather than neutral, water reflects with a soft bloom on the highlights, and the colour grading pushes saturation a little past what vanilla would give you. Volumetric light, godrays and waving vegetation fill in the rest. Nothing here is technically extreme, and that restraint is exactly why a GTX 1050 with 2 GB of VRAM can carry it.
The version range is the other reason it endures. BSL runs on Minecraft 1.7.10 through 26.2, on both Iris and OptiFine, which puts it inside old modpacks that no recent shader will even start on. Combined with a medium performance cost and a settings menu written in plain language, it is the pack you install when you want the question settled rather than researched.
BSL Shaders against vanilla Minecraft
BSL leaves every block texture exactly as it found it and rewrites what happens to the light falling on them. None of it requires a decision from you first. Here is what changes once it is switched on:
- Shadows: the sun and moon each drag a moving shadow behind every block, tree and mob, lengthening and shortening as the day runs.
- Volumetric lighting: light becomes visible in the air itself, so shafts hang between trees and pour out of cave mouths instead of only landing on the floor.
- Reflections: water, ice and polished blocks start mirroring what stands above them, with the warmth BSL applies to everything else kept intact.
- Bloom: glowstone, lava and torches bleed light into the pixels around them, which is where most of the pack's famous warmth actually comes from.
- Motion blur: fast movement smears between frames rather than stepping, so sprinting and mine-cart rides read as speed instead of as stutter.
- Custom sky: vanilla's sky is replaced with BSL's own gradient, sun, moon and stars, built to hand off into its golden sunsets.
- Overall direction: a warm, generous take on Minecraft that looks finished the moment you enable it, which is why so few people ever open its settings menu.

| Trade-off | Some effects can feel over-saturated by default |
How to install BSL Shaders
- 1Set up a shader loader first. BSL runs on OptiFine and on Iris with Fabric, so either route works and you can use whichever you already have.
- 2Download the BSL Shaders .zip from the official source linked further up this page. Leave it as a .zip; unpacking it stops the loader from recognising it.
- 3Start Minecraft on the OptiFine or Iris profile, then go to Options, Video Settings and open Shaders, which Iris calls Shader Packs.
- 4Use the folder button in that screen, called Shaders Folder on OptiFine and Open Shader Pack Folder on Iris, and drop the .zip into the window that opens.
- 5Back in the menu, click BSL Shaders to select it and confirm with Apply or Done. The first load pauses while it compiles, which is normal.
One thing specific to BSL: you do not need to open the settings menu afterwards. The default profile is the one the pack is designed around, so if you install it and immediately start hunting for options, you are working against how it was built. Come back to the menu only if the warmth of the grading is more than you want.
Running BSL Shaders smoothly
BSL Shaders sits in the medium-impact tier, which in practice means a noticeable but manageable drop from vanilla on a dedicated card. It is one of the reasons the pack keeps getting recommended: the frame cost rarely surprises anyone.
The stated baseline is a GTX 1050 or RX 560 with 2 GB of VRAM and 4 GB of system memory. That is a card from 2016, and CaptTatsu has kept the pack inside that envelope through years of feature additions rather than letting the requirement drift upward.
Version support runs from Minecraft 1.7.10 through 26.2, which is the widest range on this site alongside Sildur's. Running it outside that window can produce visual glitches until the author catches up, so match your client to a supported release rather than assuming forward compatibility.
If you do need frames back, shadow distance is the first slider that matters here, and it costs you less visually than render distance does. Because the baseline cost is modest, most people on a mid-range card can go the other way and raise render distance or add an HD texture pack instead.

What to turn down first in BSL Shaders
BSL puts its settings behind a tidy menu, and three of them account for nearly all of the cost on a card that is struggling.
- 1
Shadow resolution: the single biggest saving here. Halving it softens shadow edges at a distance and nothing else.
- 2
Volumetric lighting: expensive in every scene, visible mainly where there is something in the air. Turn it off in a desert, back on in a jungle.
- 3
Motion blur: free to remove and worth removing for survival play, since it smears exactly the movement you are trying to read.
Colour grading and waving plants cost almost nothing, so leave them alone: they are much of why the pack looks finished.
How many people run BSL Shaders?
No other pack we list comes close: BSL is the only one past a hundred million installs, and it reaches that on two platforms at once rather than through one big listing. For a pack that still starts on a 1.7.10 client, that is a very long tail of people who never had a reason to switch.

Installation GuideSomewhere to run BSL Shaders
BSL is the pack most people install first, which makes it the one your friends are most likely to already have. On a shared world that means the same sunset over the same base, on everyone's screen at once.
BSL itself never touches the server: it renders on your machine through Iris or OptiFine, and a friend who has not installed it sees the same world with plain lighting. The server is the shared part, the shader is the personal part.
