Continuum Shaders vs Rethinking Voxels

Continuum Shaders is a set of customizable shaderpacks for Minecraft Java that adds graphical effects, with Continuum 2.1 available free through Focal Engine. Continuum 2.1 includes a physically based sky and material system, ambient light, reflections, and volumetric clouds, air, and water. Camera settings, color grading controls, and custom LUT uploads provide further image adjustments. Focal Engine is required for both Continuum 2.1 and Continuum RT, and using the engine requires a Continuum Graphics account. Continuum Early Access costs $15, paid once and gives access to in-development, non-ray-traced shaders; it currently includes Continuum Legacy, which is in Alpha. The maker plans a full free release of Legacy. Listed Minecraft versions are 1.14.4, 1.16.5, 1.17.1, 1.19.2, 1.20.1, and 1.20.4, with both loader types supported. Effects include physically based lighting, water features, rain, puddles, fog, and color grading. Performance depends on hardware, and some effects are expensive despite optimization. The license is limited to personal, non-commercial use.
