This repository contains plugins for USD, and plugins for third-party software to support a USD pipeline. These plugins are developed and maintained by DreamWorks Animation.
Enables drawing packed prims from Pixar's USD Import in the viewer using Hydra, which is significantly faster for drawing and playback. Same code as this PR:
PixarAnimationStudios/OpenUSD#723
A suite of plugins that can import USD geometry, cameras, and lights into Nuke. This is currently a beta release.
usdat is USD-ascii with templates. It enables layer re-use with different string values (such as asset instance name) within a common layer.
This code is released under the Apache License, Version 2.0, which is a free, open-source, and detailed software license developed and maintained by the Apache Software Foundation.
This repository is somewhat unusual in that the install process requires merging its contents with the USD repository first, and then using USD's build_usd.py to build and install the plugins. We provide a small utility to streamline the merge process. This structure allows us to use Pixar's CMake utilities in our CMakeLists.txt files, and while not ideal, is hopefully sufficient until a proper solution for delivering USD plugins is devised.
USD-19.7 (other versions may work but will require a manual merge process)
Houdini-16.5 (for Hydra integration)
Nuke-10 or Nuke-11 (for Nuke plugins)
Run merge_plugins.py and supply a path to your local USD repository, and specify which plugins you would like to merge as arguments.
python merge_plugins.py /path/to/USD (--nuke) (--houdini_hydra) (--usdat)This will merge and / or copy the relevant files from this repository to the USD repository. If this results in merge conflicts (if you have modified your local USD repo), you will need to resolve them manually.
Once this is complete, you can use USD's build_usd.py from the USD repository location to build and install these plugins.
python build_scripts/build_usd.py --houdini --houdini-location /path/to/houdini16.5python build_scripts/build_usd.py --nuke --nuke-location /path/to/nuke10_or_11python build_scripts/build_usd.pyLaunch Houdini with Pixar's USD plugin. USD imported with Pixar's USD Import will automatically be drawn in the viewer using Hydra.
Add $USD_DIR/third_party/nuke/plugin to $NUKE_PATH before launching Nuke.
Once in Nuke, you can create a ReadGeo node or a Camera node and supply a USD file to import data from USD.
Once installed, the usdat FileFormat will be available to USD and automatically discovered from the plugin registry. You can start using usdat layers in your assets and stages without additional configuration.
