AstraLex Shaders is a fantasy-leaning shader pack for Minecraft Java built on Iris and OptiFine. Created by LexBoosT as an edit of BSL Shaders, it layers extra customization options, colored lighting, and atmospheric effects on top of that familiar base pipeline, and its latest release covers Minecraft 1.16.5 through 1.21.11.
What AstraLex changes in-game
AstraLex reworks lighting, water, and sky rendering with a stylized, slightly cartoon-leaning look rather than a strictly realistic one. The pack ships with a large set of toggles so players can shape the final look instead of relying on a single fixed preset.
- Reworked water with reflections and adjustable wave detail
- Dynamic shadows with configurable softness and distance
- Volumetric clouds and stylized sky colors
- Bloom, depth of field, and other post-processing toggles

AstraLex and BSL Shaders
AstraLex is built as an edit of BSL Shaders rather than a shader written from scratch. It keeps the same underlying rendering approach as BSL while adding its own presets, extra effects, and configuration options on top. Players moving from BSL will find a familiar settings layout with a different visual direction, and community showcases commonly refer to AstraLex as the BSL edit for that reason.
Performance and compatibility
AstraLex runs on Iris or OptiFine only and is not built for Fabric or Forge rendering mods outside of Iris. Because most effects are individually toggleable, players on older or weaker hardware can turn off the heaviest options, such as advanced reflections and volumetric clouds, to reduce the load rather than relying on a single fixed performance tier.

Questions about AstraLex Shaders.
5 questions
How do I install AstraLex Shaders?
Install Iris or OptiFine for your Minecraft Java version first. Download the AstraLex zip file from its Modrinth page, then place it in the shaderpacks folder inside your .minecraft directory without unzipping it. Open the shader options menu in game and select AstraLex from the list to activate it.
Is AstraLex Shaders the same as BSL Shaders?
No, but the two are closely related. AstraLex started as an edit of BSL Shaders and carries over the same base rendering pipeline, then layers on its own preset options, lighting tweaks, and extra visual effects. Players familiar with BSL will recognize the underlying structure while getting a different look and feature set.
Which Minecraft version does AstraLex Shaders support?
The latest release of AstraLex Shaders lists support from Minecraft 1.16.5 through 1.21.11 on Iris and OptiFine. Always check the version list on the Modrinth page before downloading, since shader compatibility can shift with major Minecraft updates.
Is AstraLex Shaders good for low-end PCs?
AstraLex offers extensive in-game configuration options, so effects like reflections, shadows, and clouds can be scaled down individually to ease the load on weaker hardware. There is no guaranteed frame rate for any specific setup, so test the default preset first and disable heavier options as needed.
Where can I download AstraLex Shaders?
AstraLex Shaders is distributed through its Modrinth project page. Use that link to get the current version file, since the license does not permit mirror hosting elsewhere.
