Simple mod that can render blocks and items on-demand with a keybind (default `).
Hover over the item and press the key to render it and save it to a file. Hold CTRL while pressing the render key to open a GUI that lets you enter a comma-separated list of mod ids to render.
This is the page for the original mod as created and "maintained" by unascribed. It's effectively a worse version of the later fork by AterAnimAvis, which can be found here: https://www.curseforge.com/minecraft/mc-mods/block-renderer AterAnimAvis' fork has many improvements and is superior to this version in almost every way. The 1.16 version of this was released because I received a PR to update the mod and forgot the fork existed.
