Synced folders

Synced storage

The Asset Hub is a shared data storage service that automatically synchronizes content in ...\Pixotope\Synced Storage between connected machines.

It contains 3 sub folders

  • Projects for your project folders/files (levels, maps, .uproject)

  • Common for any other files you want to sync across machines

  • Internal which stores metadata for the Asset Hub service

The Internal folder is essential, and must not be edited or deleted!

The Synced Storage folder lives outside the installation folder and its path can currently not be changed.

Synced config

The Asset Hub also synchronizes important configuration files that need to be shared for setup, like lens files and XR calibration files, in ...\Pixotope\[Version number]\Synced Config.

It contains 2 sub folders

  • Lens files stores the default lens files with each installation, to use in the Camera tracking panel

  • Pixotope XR Calibration for custom calibrated LUTs generated in the Color matching panel

The Synced Config folder is for internal use and lives inside the installation folder.

Ignored files/folders

By default, the following folders are ignored:

CODE
DerivedDataCache/
Intermediate/
Saved/

To create your own list of what files/folders to ignore

  1. Create a .pxignore file in your projects or common folder
    for a project: Synced Storage/Projects/[Project folder]/.pxignore
    for Common: Synced Storage/Common/.pxignore

  2. Add the files and folders to ignore based on the following pattern

.pxignore pattern

  • One rule per line

  • Empty lines are permitted and are ignored

  • Lines starting with # are considered a comment and are ignored

  • Behaves like Unix shell patterns, more-less same as .gitignore. Few examples:

    • Temp - Ignore file or directory <Workspace>/Temp

    • Temp/ - Ignore directory <Workspace>/Temp

    • **/Temp - Ignore file/directory Temp anywhere in workspace tree.

    • **/*.{obj,tmp} - Ignore file/directory with extension .obj or .tmp anywhere in workspace tree.

For more information about supported patterns, see the glob library → https://www.npmjs.com/package/glob

  • To ignore a file/folder, it must be ignored before it was pushed for the first time

    • If a file/folder is already tracked, it is not affected by the rules

  • Ignore files in subdirectories are not taken into consideration

  • In case there are any non-ASCII characters, the file must be encoded in UTF-8
