When this mode is applied, the reflection function of the shader is turned off.
I went into the setup and made sure the reflection function was on, and I tried rebooting the game or turning the sader setting back off and on, but it didn't work out.
I deleted the mod and when I see that the feature came back, it seems to conflict with this mod.

Shader reflection is working well.

Reflections turned off after applying this mode.

However, the mode itself works fine, it just crashes with the shader.
