Within RenderPostProcessing.java on line 115,

effect.setSampler("NoiseSampler", () -> minecraft.textureManager.getTexture(NOISE_SEED).getId());

Creates an error for attempting to access a private field. Changing the line to the following appears to work, but I can't promise it still has the desired function.

effect.setSampler("NoiseSampler", () -> minecraft.getTextureManager().getTexture(NOISE_SEED).getId());
