Candela Shaders
What it is
Candela Shaders is a free shaderpack for Minecraft Java Edition, designed to add visual effects without putting heavy demands on the GPU. It is listed for Linux, macOS, and Windows, with a low hardware tier. The shader offers colored, translucent shadows with adjustable blur, separate brightness settings for times of day and dimensions, and Gaussian bloom controls that can be adjusted horizontally and vertically. Sunlight shafts add godrays; other effects include moving foliage and water, depth-based block outlines, and a pink color tone intended to create a liminal atmosphere. The project says a recent optimization improves performance on older hardware. Installation requires Iris Shaders for Minecraft (Fabric): download the ZIP from GitHub Releases or Modrinth and place it in the `.minecraft/shaderpacks` directory. The Modrinth listing identifies Minecraft Java Edition versions 26.3, 26.2, 26.1.x, and 1.21.5–1.21.11, and lists Iris and OptiFine as platforms. The repository uses the MIT License.
