ATTRIBUTION
================================================================================

If you redistribute Crate or a derivative of it, please retain this NOTICE
file as required by Section 4(d) of the Apache License 2.0. The contents of
this file are informational and do not modify the License.

A user-visible acknowledgement of the original project is appreciated where
practical (for example, in an About dialog or documentation footer):

This is a request, not a requirement of the License.

================================================================================
USER RESPONSIBILITY
================================================================================

By using Crate you acknowledge and accept the following:

  1. You are solely responsible for how you use Crate, including any
     output it produces, any files it modifies, any caches it writes,
     and any third-party software it invokes on your behalf. The
     "Disclaimer of Warranty" and "Limitation of Liability" sections of
     the Apache License 2.0 apply in full.

  2. Crate performs file operations including thumbnail generation,
     cache writes, file moves to a "Library_Bin" trash folder, and
     metadata writes (".meta.json" files alongside assets). You are
     responsible for ensuring you have the necessary permissions on
     your file systems and for maintaining your own backups of any
     irreplaceable data.

  3. Crate caches thumbnails and sprite frames on disk in a location
     of your choice. You are responsible for managing the size and
     contents of these caches and for ensuring the cache directory
     does not contain sensitive material that would be exposed via
     the cache to other users sharing the same cache path.

  4. Crate does not transmit data over the network. Any network
     activity observed during use of Crate originates from Nuke
     itself or from third-party tools that Crate has invoked at your
     request, not from Crate's own code.

  5. You are responsible for the legality of the assets you browse,
     import, modify, or distribute using Crate. Crate does not perform
     copyright or licensing checks on user content. Importing assets
     into Nuke via Crate's "Add to Cart" or import features does not
     grant you any rights to those assets that you did not already have.

  6. You are responsible for ensuring that your use of Crate complies
     with the licence terms of every third-party tool that Crate may
     invoke (see "Third-Party Software" below). The author of Crate
     is not a party to those licences and provides no warranty
     regarding their compatibility with your use case.

================================================================================
THIRD-PARTY SOFTWARE
================================================================================

Crate invokes the following third-party command-line tools and applications
as external processes. Crate does NOT statically link to, embed, or
incorporate the source code of any of these tools. They are independent
programs that the end user must install and license separately. Crate
communicates with them only through standard subprocess calls (command-line
arguments, file I/O, and process exit codes).

Because Crate uses these tools as separate processes — not as linked
libraries — Crate is not a derivative work of those programs under their
respective licences. Each tool remains under its own licence, and any
redistribution of those tools (whether bundled with Crate or distributed
separately) must comply with that tool's individual licence terms.

If you redistribute Crate together with pre-packaged copies of any of
these tools, you are responsible for complying with the licensing,
attribution, and source-availability requirements of each bundled tool.
Crate's Apache 2.0 licence does NOT grant any rights over these
third-party tools, and the original author of Crate is not responsible
for licence compliance regarding them.

HOST APPLICATION AND IN-PROCESS LIBRARIES
--------------------------------------------------------------------------------

The following are loaded in-process by Crate via the user's Nuke
installation. Crate does not redistribute or modify any of them.

  Nuke / NukeX (The Foundry)
    Crate is a script that runs inside Nuke. It uses Nuke's Python API
    (the `nuke` module) and Qt bindings (PySide2 on Nuke 15, PySide6
    on Nuke 16+). Nuke is proprietary commercial software, licensed by
    The Foundry. A valid Nuke licence is required to run Crate. Crate
    does not redistribute, modify, or bundle Nuke.

  Qt for Python (PySide2 / PySide6)
    https://www.qt.io/qt-for-python
    Licence: GNU Lesser General Public License v3 (LGPLv3) or
    commercial. Crate uses whichever PySide binding is provided by
    Nuke and does not redistribute Qt.

INCLUDED CODE FROM THIRD-PARTY PROJECTS

Crate's PLY-to-SPLAT converter (`crate_ply_to_splat.py`) is derived
from the `convert.py` script in the antimatter15/splat project, used
under the MIT License.

================================================================================
CAMERA DATABASE
================================================================================

Crate includes a camera database feature (Settings → Camera Database)
that allows users to maintain a personal database of camera sensor
specifications for use with Nuke's Camera nodes.
The Camera module ships with a reference database of digital cinema,
broadcast, drone, mobile, and film camera sensor specifications. This
data is derived in part from VFXCamDB (https://vfxcamdb.com/) maintained
by Tony D'Agostino and Matchmove machine (https://camdb.matchmovemachine.com/)
maintained by Matchmove machine, both of whom have granted permission for
their databases to be used in Crate.
We are genuinely grateful and the Camera module would not exist in its
current form without the work of Tony D'Agostino and Matchmove machine.
If you find this data useful, please consider supporting VFXCamDB
(https://vfxcamdb.com/donate/) and supporting Matchmove machine
(https://camdb.matchmovemachine.com/donate) directly.
Any inaccuracies in Crate's database are ours, not VFXCamDB's or
Matchmove machine's; corrections are welcome via the issue tracker at
https://github.com/CrateTools/CrateCamDB, and significant corrections
will be reported back to the parent databases.
Users may extend, edit, or replace the camera database freely. The
camera database is provided under the same Apache 2.0 licence as Crate.
