LiDAR-S is a cursed shader pack by LoLip_p that works as a lidar shader for Minecraft Java. It runs on Iris and OptiFine and is needed on the client side only. Press Shift and the pack renders a 3D image of your world that you can walk around in.

- Needs no other mod beyond a shader loader.
How to install LiDAR-S
Shader packs need a loader on Java Edition, and this one lists builds for both Iris and OptiFine. Iris runs on Fabric or NeoForge. If you have not set a loader up yet, the shader install guide walks through Iris and OptiFine step by step.
- 1.Install Iris or OptiFine.
- 2.Put the LiDAR-S .zip into the shaderpacks folder inside your .minecraft folder.
- 3.Launch Minecraft and open Options, then Video Settings, then Shader Packs.
- 4.Select LiDAR-S and load a world.
- 5.Press Shift to start scanning.
Trade-offs
This is a one-idea pack. The scan is the feature, so expect a stylised, cursed look rather than a general-purpose lighting upgrade for everyday building. The client needs the pack and a server does not support it, so it will not change what other players see on a multiplayer world.
Bedrock cannot run Iris or OptiFine, so the pack is Java only. Modrinth's potato tag marks it as light, but that is a category label and not a hardware promise. If the pack fails to load, check the shader troubleshooting guide.
Questions about LiDAR-S.
3 questions
How do I install LiDAR-S?
Install Iris or OptiFine, then place the LiDAR-S .zip in the shaderpacks folder inside .minecraft. Start the game, open Video Settings, go to Shader Packs, and select LiDAR-S. Press Shift in a world to trigger the scan effect.
Does LiDAR-S work with Iris and OptiFine?
Yes. The pack lists builds for both Iris and OptiFine, and neither build requires any other mod. Pick whichever loader you already use. It is a Java pack and does not run on Bedrock.
Is LiDAR-S good for low-end PCs?
Modrinth files it under the potato category, which marks it as light on hardware. That is an editorial tag rather than a promise, so results still depend on your machine and the other mods you run.
