The Bear Minimum shaders (TMBS)

TBM is a OptiFine shader. It offers blocky shadows and mirror-like reflections in water, ice and other commonly reflective blocks, and a slight overhaul of emissive lighting; all in a very lightweight way. Its goal, above all else, is to keep with Minecraft’s model-like appearance without compromising performance. It wasn’t built with mod support in mind, nor it has flair features.
