A free, open-source OpenDRT display rendering transform packaged as an OpenFX plug-in for DaVinci Resolve, Fusion, Nuke and other OFX hosts — GPU-accelerated with Metal on macOS and CUDA on Windows / Linux.
OpenDRT is Jed Smith's open display transform. This repository wraps it as an OFX plug-in and provides cross-platform builds. It is licensed under the GNU General Public License v3.0 — see LICENSE and NOTICE.
This is the same OpenDRT that ships as the "6A. OpenDRT" tool inside the Dec. 18 Studios Look Dev Tools suite. The transform is identical; this build is standalone and free.
Download the build for your platform from the
Releases page, then
copy the OpenDRT.ofx.bundle into your host's OFX plug-in directory:
| Platform | Asset | Install path |
|---|---|---|
| macOS (universal) | OpenDRT_<ver>_macOS_universal.zip |
/Library/OFX/Plugins |
| Windows (CUDA) | OpenDRT_<ver>_windows_x86_64_cuda.zip |
C:\Program Files\Common Files\OFX\Plugins |
| Linux (CUDA) | OpenDRT_<ver>_linux_x86_64_cuda.tar.gz |
/usr/OFX/Plugins |
Unzip so the final layout is e.g. /Library/OFX/Plugins/OpenDRT.ofx.bundle/…,
then restart your host. The effect appears under the Dec. 18 Studios group
as OpenDRT.
The OFX SDK is cloned on demand (not vendored). From the repo root:
cd source
git clone --depth 1 https://github.com/AcademySoftwareFoundation/openfx.git ofx-sdk
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build --config ReleaseThe staged plug-in is written to source/bundle/OpenDRT.ofx.bundle. Copy it to
the OFX plug-in directory for your platform (see the table above).
Requirements
- CMake ≥ 3.20 and a C++17 compiler.
- macOS: Xcode command-line tools (Metal backend, no extra deps).
- Windows / Linux: the CUDA Toolkit for the GPU backend. CMake auto-detects it; without CUDA the plug-in still builds but the CUDA path is omitted.
CI builds all three platforms on every v* tag — see
.github/workflows/.
