Starting from version 3.11.0, when loading both this mod and the "(internal)" option in the optifine shader, nothing will be visible. (other shaders will be normally except for this one)

We're unable to support or resolve any issues that occur when using Optifine unfortunately. Optifine is a closed source mod that makes many unknown changes to the rendering pipeline.

We recommend using open-source alternatives like Rubidium and Oculus.
