Customization

Provided within the pack zip, you may find a file called init_LUT.psd, which will allow you to customize the look and feel of this shader.

Customization Instructions

Open init_LUT.psd into your favorite photo editor (IE GIMP, Photoshop, Affinity Photo)

I personally use the free online Photoshop alternative Photopea
You can also just use the unmoddified init_LUT.png which is also provided in the zip

Apply as many adjustment layers, or edit the ones I have pre-selected, to achieve the look you desire

These can be found under Layer > Add New Adjustment Layer

Hide the color preview layer HIDE BEFORE EXPORT
Export into the pack as assets\minecraft\textures\effect\lut.png or shaders\lut.png, depending on whether you are using Vanilla or Iris/OptiFine
