Manual LUT Capture

Capture LUTs directly from the OFX plugin without the menu bar app

You can capture LUTs directly from the OFX plugin inside DaVinci Resolve, without using the menu bar app. This is useful if you prefer a fully manual workflow or don't have the app installed.

Prerequisites

• Nobe LutBake OFX plugin installed in DaVinci Resolve

• Node graph set up with a HALD Generator node before your corrections and a LUT Generator node after them (see Getting Started for setup instructions)

Step 1: Enable the HALD Generator Node

Make sure the HALD Generator node is enabled (not bypassed). You should see a colored grid pattern overlaid on the top-left corner of the image in the Resolve viewer.

Unlike the menu bar app workflow — where the app toggles the HALD node automatically — in the manual workflow you need to enable and disable it yourself.

Step 2: Match Settings on Both Nodes

Open the OFX settings on both nodes and verify that the HALD Level is the same. If the levels don't match, the extracted LUT will be incorrect.

Also check that your timeline resolution is large enough for the selected HALD level:

HALD Level	Minimum Resolution
4	64 × 64
8	512 × 512
10	1000 × 1000
12	1728 × 1728
16	4096 × 4096

Disable spatial effects before capture. Blur, sharpening, noise reduction, grain, Power Windows, and similar effects between the two LutBake nodes will corrupt the captured LUT. Disable them or place them on nodes outside the capture range. See Getting Started for more details.

Step 3: Set the Output Path

On the LUT Generator node, set the Output Path field to the desired .cube file location. The target directory must already exist — the plugin will not create it.

You can also configure these optional settings on the LUT Generator node:

• LUT Size — 17³, 33³, 64³, 65³, or 100³. Use 64 with HALD 8 or 100 with HALD 10 for zero interpolation error.

• Title and Description — metadata written into the .cube file header.

• Decimal Precision — number of decimal places in the output (1–16, default 10).

• Clamp Output 0..1 — clamps values to the [0, 1] range for broad compatibility (enabled by default).

Step 4: Save the LUT

Click the Save LUT button on the LUT Generator node. The plugin reads the color-corrected HALD pattern from the image, extracts the 3D LUT, and writes the .cube file to the specified path.

Once the LUT is saved, disable the HALD Generator node to restore normal viewing.

Your .cube file is ready to use in any application that supports 3D LUTs.

For best results, use YRGB color science in DaVinci Resolve when capturing LUTs.
