TinyRender

A mod that unlocks the minimum render distance to 1 chunk (vanilla minimum is 2) via the graphics settings slider, and also adds the /rd command to set render distance from 1 to 32 chunks, which works both with and without Embeddium/Rubidium — with these mods installed, 1 chunk render distance is available through the /rd 1 command. This can be useful if your computer is a total potato.
