USD Viewer Action

Opens the selected elements in USD viewer (usdview)

An element can also point to a folder, every USD file inside the folder gets opened

Requirements

  • das element 2.2 or newer

  • OpenUSD (usdview)

Install

Copy the folder from the download into the Das Element hooks folder.

Das Element loads hooks from these folders, in order of priority:

  1. $DASELEMENT_HOOKS

  2. $DASELEMENT_RESOURCES/scripts/hooks

  3. ~/.das-element/scripts/hooks (the default when no environment variables are set, or $DASELEMENT_USER_CONFIG_PATH/scripts/hooks if that is set)

Configure

Open action_usdview.py and edit the line containing {CHANGE HERE} in the USER CONFIGURATION block, so APP points to the usdview executable:

Linux

/usr/local/USD/bin/usdview

macOS

/usr/local/USD/bin/usdview

Windows

C:/OpenUSD/bin/usdview.cmd


When the USD bin folder is on the PATH, setting APP to usdview is enough. Useful options for APP_ARGS are listed in the usdview documentation, for example ["--norender"] for a fast hierarchy-only browser.

Restart Das Element afterwards so the button appears.

Test outside Das Element

python action_usdview.py /path/to/scene.usd
python action_usdview.py /folder/with/usd/files
