As the title states, I'm having an issue with shaders and horizons in combination. The shader I'm using is bliss shader through iris. As the image shows, when I look at distant water in certain directions it all turns black. I can make that black border move by changing my chunk render distance up and down, but can never get it to go away fully. It seems to be some issue with the water specifically as no other blocks do this. If anyone has seen a similar issue and has a fix I'd really appreciate it as it really kills the immersion that distant horizons brings. I'm very new to java Minecraft (just got it last week) and modding in general. Thanks in advance.
