They look like this (flat squares) until I'm like 3 blocks away, I use kappa shaders (extreme settings) and 512x pack, no DH (LOD), when I was using complementary reimagined this doesn't happen (however sides of dirt block glitched sometimes)

I am using iris+sodium currently. I have the resource package in the resource folder. When I am in game it doesn't show up as a option to activate it. From in game when I select "open folder" it is there. I have even tried the "click and drag" method. And reloaded the game a few times. Trying to get the 64 working before pushing it more.

Here's the official poster for the 15th release!
