Keep in mind that color grading will only work in the MFP game version.

MFP uses areas to change color gradings, but since there's no available MFP editor suite, you need to re-add it manually to the TDD suite (which needs to be already installed for this).

To do that, you need to open editor/AreaTypes.cfg and paste this in the beginning of the file:

       <Type Name="ColorGrading">
            <EditorSetupVars>
                <Var Name="Color" Value="1 1 0 1" />
            </EditorSetupVars>
            <Vars>
                <Var Name="LookUpTable" Type="File" Extensions="png"  DefaultValue=""          Description="Colorgr:) file" />
                <Var Name="FadeTime" Type="float"  DefaultValue="1.0"     Description="Fade time"/>
            </Vars>
        </Type>

From now on, in the Level Editor you can select the area tool and choose the ColorGrade type. It will allow you to place new color ColorGrade areas, pick a color grading texture, and change the fade time.

Moreover, now the ColorGrade areas in the original maps show up in the editor and you can customize them as you want. The areas will show up as yellow.

Color grading textures are located in \textures\gradingmaps.

Color grading is a way to map the color of a pixel to another color. This can be used to change the brightness, contrast, hue, saturation, … of a whole image.
It is possible to smoothly fade between two different grading templates.
It uses a small 3D texture with a color as input and another color as output.

Requirements

Photoshop or any other image editing software

Setup

Take a screenshot of the game with color grading disabled

Place the color strip anywhere in the image

Flatten the image to merge all the layers

Select “Image > Mode > 16 Bits/Channel” in the top menu

Adjustments

Use any of the options in “Image > Adjustments”

These can be used to change the brightness, saturation, contrast and so on

Any changes you see on the image in Photoshop will carry over to the game

Layers

It is also possible to use the any of the layer blend modes

There are two kinds of layers allowed:

Solid color

It is possible to duplicate the first layer and make adjustments to it and then blend it

The use of Layer Masks is allowed as long as they are generated from the image and not hand painted

Saving

Select “Save As…” and set the format as “PNG“ and save it in the folder “\textures\gradingmaps”
