Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Licensing distributables with default third party plugins

Hello world,

I have been working on a little indie project for over a year now and would like to make it commercially available. Just need to complete the licensing requirements to be distributed along with the release.

My project has the default 4.18 plugin set (minus vr and ar). When i package it, under "\engine\binaries\thirdparty" i get the following

  1. nvidia\nvaftermath

  2. ogg

  3. PhysX

  4. Vorbis

  5. Windows\directx

I could really use some guidance on how to proceed from here in regards to what licenses (or legal docs) should i distribute along with the release. Wouldn't want to mess things up after spending so much effort on it..

Product Version: UE 4.18

Hi Hellwitu. I'm Epic's lawyer, so I can't give you legal advice or interpret your obligations under third party licenses. But, I wanted to point you to some resources that may be helpful.

You can find the relevant licenses for the third party software in the "Engine/Source/ThirdParty/Licenses/" folder and/or in the relevant .tps file. Those licenses will specify your obligations with respect to the third party software.

A helpful site to understand common licenses is: https://tldrlegal.com/

While i do struggle with license terminologies, i managed to gather the following info.

Licenses required in final ship:

1: EULA for your product between seller and buyer.

2: EULA for your product that explicitly disclaims any representations, warranties, conditions, and liabilities related to the Unreal Engine.

3: License agreements of third-party software your product uses and provide notice to your end users if required. (In the above case, Nvidia & Ogg)

4: In-game Credits: “[Product name] uses the Unreal® Engine. Unreal® is a trademark or registered trademark of Epic Games, Inc. in the United States of America and elsewhere” “Unreal® Engine, Copyright 1998 – xxxx, Epic Games, Inc. All rights reserved.”

Regarding 3rd party software, i have noted the key points in their licenses (under "Engine/Source/ThirdParty/Licenses/" ):

1: nvidia\nvaftermath -...You may exercise your license rights pursuant to Subsection 1(b) above pursuant to the terms and conditions of any form of end-user software license agreement, provided Your end-user agrees to be bound by terms and conditions that are as protective of NVIDIA’s Intellectual Property Rights in the Software as this Agreement.

2: ogg -...Redistributions in binary form must reproduce the above copyright notice, this list of conditions and the following disclaimer in the documentation and/or other materials provided with the distribution

3: PhysX -...Custom agreement between Epic/NVIDIA. Lisence none.

4: Vorbis -...OggVorbis is a combined product.

5: Windows\directx -...License none

If someone could help confirm that would be of great help for me.

As mentioned, I can't provide you with legal advice since I'm Epic's lawyer. But, you are correct that the UE4 EULA requires the items you've listed under "Licenses required in final ship". I'll let others comment on the remaining points.

We provide some guidelines to help you understand what you have to do to publish a product under the UE4 EULA. I hope you find it helpful.
