What is a LUT?  

LUT, or ‘LookUp Table’, are a kind of color filter you use to alter the colors in your game. They apply predetermined sets of mathematical formulas to your game’s existing colors to change those colors and achieve a desired look.

Requirements  

All ‘LUTs’ effects are developed for ‘Universal Render Pipeline’ (or URP), which means they will not work with Built-In, or HDRP.

Unity 6 or higher  

All effects are compatible with Unity 6, and use the new Render Graph. You will need to have URP version 17.0.2 or higher installed. In the official documentation you can find the steps to install it correctly.

Make sure that the ‘Compatibility Mode’ is disabled (Project Settings > Graphics > Render Graph).

Unity 2022.3 or higher  

You will need to have URP version 12.1.15 or higher installed. If you don’t know how to do it, I recommend you to follow this official tutorial.

Using them in the Editor  

Once installed, you have to add the effect you want to use from ‘LUTs’ as a ‘Render Feature’. This official tutorial tells how to do it.

Remember that the camera you are using must have the ‘Post Processing’ option enabled.

All ‘LUTs’ have an inspector similar to this one:

With the intensity (1) set to 1.0 the effect is fully applied, with 0 it is deactivated and with the intermediate values you get a mix between the original and the final image.

There are two modes (2), the quality mode and the performance mode. The first one uses high resolution 3D textures, while the second one uses smaller versions. For VR and mobile I recommend the second mode.

Each lut is contained in a profile that you can find in the ‘Profiles’ folder. By clicking on ‘Profile’ (3) you will see all the available ones.

All ‘LUTs’ have an advanced color grading panel. Check ‘Color grading’ (1) to activate it.

‘Exposure’ (2) changes the exposure, or brightness. Just below you have a contrast control (3) and an HDR color (4) without alpha channel to tint the image.

To move the color wheel, use ‘Hue’ (5). To change the amount of color, use ‘Saturation’ (6).

Select the tone operator, ‘Tonemap’ (7), that best suits your needs. The most popular ones are available: Neutral, ACES and Reinhard. If you want more, you may be interested in ‘Artistic: Tonemapper’.

With ‘White balance’ (8) you can adjust the perceived temperature of the image. First you can make it perceived cooler or warmer. The next parameter modifies the color used to vary the perceived temperature.

‘Split toning’ (9) is used to tint shadows and highlights of an image separately. A typical example is to push shadows toward cool blue and highlights toward warm orange.

‘Channel mixer’ (10) allows you to combine input RGB values to create a new RGB value. For example, you could swap R and G, subtract B from G, or add G to R to push green toward yellow.

The last setting is ‘Shadow Midtones Highlights’ (11), it works like split-toning, except that it also allows adjustment of the midtones and decouples the shadow and highlight regions, making them configurable.

They also have an ‘Advanced’ panel with these options:

Activate ‘Affect the Scene View?’ (1) if you want the effect to be applied also in the ‘Scene’ window of the Editor. With ‘Filter mode’ (2) you can change the type of filter used.

Although it is not recommended to change it, with ‘RenderPass event’ (3) you can modify at which point in the render pipeline the effect is applied. Finally, activate ‘Enable profiling’ (4) to show in the ‘Profiling’ window the metrics of the effect.

VR  

To increase compatibility with VR devices, I recommend that you select ‘Stereo Rendering Mode’ in ‘Multi Pass’ mode:

Using them in code  

Once you have added the effect in the Editor, you can also handle ‘LUTs’ effects by code.

First you must add the corresponding namespace. They are all of the style ‘FronkonGames.LUTs.XXXX’, where XXXX is the name of the effect. For example, if the effect you want to use is ‘Cyberpunk’ the code would be:

using FronkonGames.LUTs.Cyberpunk;

To modify any of the effect parameters, you must first request its settings. In the following example we change the intensity of the effect by half.

Cyberpunk.Settings settings = Cyberpunk.Instance.settings;

settings.intensity = 0.5f;

And how can I activate and deactivate the effect? It’s as easy as that:

Cyberpunk cyberpunk = Cyberpunk.Instance;

// Switch between active and inactive.
if (cyberpunk.isActive == true)
  cyberpunk.SetActive(false);
else
  cyberpunk.SetActive(true);

You can load a profile in several ways. A profile is nothing more than a ScriptableObject, so it must be referenced by some object to be included in the build.

A very simple way is to create a MonoBehaviour and add a list of profiles to it. This way Unity will include in the build the profiles that you have referenced.

public class ProfileBank : MonoBehaviour
{
  [SerializableField]
  private List<Profile> profiles = new();

  private void Awake()
  {
    // Set a random profile.
    if (profiles.Length > 0)
    {
      Cyberpunk.Settings settings = Cyberpunk.Instance.settings;

      settings.profile = profiles[Random.Range(0, profiles.Length)];
    }
  }
}

Another method you can use, more versatile, is to move the profiles folder into the ‘Resources’ folder. Everything included in this folder will be added to the build and you can load its content with the Resources class:

// In this example the profiles are located
// inside Resources in the folder 'LUTs/Profiles/Cyberpunk'.
Cyberpunk.Settings settings = Cyberpunk.Instance.settings;

Profile profile = Resources.Load<Profile>("LUTs/Profiles/Cyberpunk/Cyberpunk_01");

settings.profile = profile;

With this method, you can unload the profile when you no longer want to use it.

Resources.UnloadAsset(profile);

If you are using an effect other than ‘Cyberpunk’ just change it to its name. Check the source code comments for more information.
