⚠️ This has been included in Iris 1.11.2, it is now only useful for older MC versions or for forks like oculus ⚠️

Faster Iris Shadow Mapping is a really lightweight mod that prevents unneeded things from rendering during the shadow pass.

This project does not replace Iris, both needs to be used at the same time for it to work.

This mod also works with oculus.

How it works

During the shadow pass, for opaque models, the color of the model won't have any visual change, a blue car and a red car both cast the same shadow, no matter their color. So what this mod does is it prevents things like the text on signs, the banner patterns, the enchantment glint etc from rendering during the shadow pass. It only improves performances when some of those are visibles.
