(v2) DaVinci Resolve

Before you can work in Resolve you'll need a one-time setup step: copy all the CUBE files from /PostProcessing/Textures/Cubes/ to Resolve's LUT folder. You can find this folder by opening Resolve, going to Project Settings -> Color Management and clicking Open LUT Folder. We recommend you put them into a separate folder, say Unity, for easier access later on. Don't forget to click on Update List after you've copied the LUTs.

Let's go over the workflow to grade Unity scenes in Resolve.

Step 1

Export the current frame in Log as EXR without color grading applied.

Step 2

Open the previously exported EXR file in Resolve. It will look wrong, but that's expected. Resolve, by default, will display EXR files in linear mode. Go to Project Settings -> Color Management and set the 3D Video Monitor Lookup Table to Linear to sRGB. The EXR should now look like a Log footage.

Step 3

In the node view or the color editing panel, right-click the only color grading node there is and assign the Unity Log To Linear 3D LUT to it. It should now look exactly like it does in the Editor.

Step 4

You can now start grading your image. Use as many node as you'd like to move between color spaces but make sure you only do global color operations. Local operators & filters can't be store in LUTs.

Step 5

Once you're done, export a CUBE by right-clicking the clip and choosing Generate 3D LUT (CUBE). Save the resulting file somewhere in your Assets folder.

Step 6

Back in Unity, it will detect the CUBE and automatically convert it to a Texture3D asset. Grab this texture and populate the Lookup Texture field in the color grading effect.

And you're done. You can keep grading in Resolve and override the previously saved CUBE file, Unity will automatically update the Texture3D used for real-time grading.

Volume blending with external LUTs is, of course, supported out-of-the-box.
