ABOUT
BSL Shaders - Classic is a shaderpack made exclusively for Minecraft: Java Edition. It's oriented towards vanilla aesthetics. This shader includes realtime shadows, volumetric light, ambient occlusion, bloom, customizable clouds and water, and built in anti-aliasing. Additional effects are available, such as depth of field, motion blur, specular and normal mapping, celshading, world curvature, and more.
