Hey. I've been playing with this mod alongside various other mods and wanted to point out an issue when using this mod with an ultrawide monitor (Mine is 3440x1440 resolution, so not sure about the 1080p ultrawide having the same issue). This issue happens to not light the edge of the screen entirely, and leaves an "unlit"/shaderless area on the edge - any coloured lighting, or simply ANY lighting just defaults the block to be fully visible. This area expands if I'm moving to the right as the camera pans across new blocks. Here are links to the pictures of the issue:

I have a lot of mods running, but simply disabling fancy lighting does fix this issue, but in turn I don't get to use fancy lighting obviously which I've grown to love. I've tested this on brand new worlds with no mods enabled but this and the same issue occurs. Hope this can get fixed so I don't sometimes see caves slightly lit, but fully visible on the edge of the screen.
