You can use this CUBE file in a Tonemapping override inside a Volume. Unity automatically interprets the CUBE file as a usable Texture3D Asset. Step 6: Import and use the CUBE file in your Scene
Save the CUBE file in your Unity Project's Assets folder. Select Generate 3D LUT (CUBE) in the menu. When you finish grading, export your work as a CUBE file. 
Make sure you only do global color operations because LUTs can't store local operators or any filters that affect neighboring pixels (such as blur or sharpen). Right-click on the EXR file in Resolve.Now import the EXR into Resolve and apply the Unity Log To Linear r1 LUT to it. Note: You only need to do step 1 to 5 once for Resolve in general, and step 6 per-project. Set the 3D Video Monitor Lookup Table to Linear to sRGB r1.In the file explorer, create a new Unity folder and copy all the previously imported LUTs you exported from Unity (see Step 2) into it.This opens your platform's file explorer at the location that stores LUTs for Resolve. In the Lookup Table section, select Open Lut Folder.Open File > Project Settings and go to the Color Management panel.This imports the LUTs into Assets/HDRP Sample Content/Post-processing/Cube LUTs/.īefore you can start color grading in Resolve, you need to set up Resolve to work with the EXR file from Unity.
In the Samples section, select Import into Project next to Additional Post-processing Data. Select High Definition RP from the list of packages on the left. Open the Package Manager window (menu: Window > Package Manager). To do this, HDRP provides a set of ready-to-use transform LUTs. 
Select Edit > Rendering > Render Selected HDRP Camera to Log EXR (or press Ctrl+Shift+Alt+E).Īfter you export the EXR file, transform the data from the format that Unity uses (Alexa LogC El.1000) to Linear RGB space, so that external software can use it. In the Scene view or Hierarchy, select a GameObject that contains a Camera component. Step 2: Render the Camera view to an EXR fileĮxport the current Camera's view to a log-encoded EXR file. Resolve only exports LUTs of size 33 so set Grading LUT Size to 33 for it to work correctly. 
Go to Post-processing > Grading LUT Size. Open your HDRP Asset in the Inspector window. To set the LUT size, use the HDRP Asset’s Grading LUT Size property. Step 1: Set up the HDRP Assetĭecide on the lookup texture (LUT) size to use for the Project, and set it in your Project's HDRP Asset. The following process uses DaVinci Resolve, but you can apply it to other digital content creation tools such as Photoshop or Nuke. Authoring lookup textures with DaVinci Resolve
