2. OPENSSL 1.1.1t
--------------------------------------------------------------------------------

The PWRWorkEditor module (Binaries/Win64/UnrealEditor-PWRWorkEditor.dll) is statically
linked with the OpenSSL 1.1.1t library distributed with Unreal Engine, used to verify the
license permit. This product includes software developed by the OpenSSL Project for use in
the OpenSSL Toolkit (http://www.openssl.org/). This product includes cryptographic software
written by Eric Young (eay@cryptsoft.com). Its license follows unchanged.

  LICENSE ISSUES
  ==============

  The OpenSSL toolkit stays under a double license, i.e. both the conditions of
  the OpenSSL License and the original SSLeay license apply to the toolkit.
  See below for the actual license texts.

3. PWRSTUDIOS BLENDER BRIDGE ADD-ON (GPL-3.0-OR-LATER)
--------------------------------------------------------------------------------

The Blender add-on in Extras/Blender/pwrstudios_blender is Copyright (c) 2026 PWRStudios
and is free software: you can redistribute it and/or modify it under the terms of the GNU
General Public License as published by the Free Software Foundation, either version 3 of
the License, or (at your option) any later version.

This add-on is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY;
without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
See the GNU General Public License for more details. The full license text is in
Licensing/GPL-3.0.txt and, next to the add-on, in Extras/Blender/pwrstudios_blender/LICENSE.

The add-on is shipped as complete source code. The restrictions of the PWRWork license
agreement do not apply to it: for this add-on only the GPL applies. The GPL covers the
add-on alone; it does not extend to the rest of PWRWork, which communicates with the
add-on only as a separate program through a local network connection.

--------------------------------------------------------------------------------
4. SEMANTIC SEARCH TABLE DERIVED FROM ALL-MINILM-L6-V2 (APACHE LICENSE 2.0)
--------------------------------------------------------------------------------

Content/Semantic/pwr-minilm-static.bin and Content/Semantic/vocab.txt are derived from the
model all-MiniLM-L6-v2 by the sentence-transformers project
(https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2), itself fine-tuned from
MiniLM (Microsoft) with the BERT uncased vocabulary (Google), released under the Apache
License, Version 2.0. Modification notice: PWRStudios ran each vocabulary token through
the model, reduced the outputs to 256 dimensions with PCA and quantised them to 8 bits; the
files contain no original network weights. Details in Content/Semantic/README.txt. The
full license text is in Licensing/Apache-2.0.txt; it is also available at
http://www.apache.org/licenses/LICENSE-2.0. The table is provided on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, as stated in that license.

5. LUCIDE ICONS (ISC LICENSE)
--------------------------------------------------------------------------------

The SVG icons in Resources/UI/Lucide were generated from Lucide 0.577.0
(https://lucide.dev), released under the ISC License; portions derived from Feather
(MIT License). PWRStudios only changed the stroke colour to white so Unreal can tint them.
