Hi @Robert.Cummings ,
The Legal status is given below
Legal Status
There is NO BINARY because it’s NOT an Epic official version. Users who are Market Creators have asked to go to 5.4 for performance reasons on Nvidia GTX VRAM being better
This version is all the patches and files to build “Luoshuangs GPULightmass”. LGPU Lightmass patches from the commit GPULightmass5-0-0-cherry-pick repository and others have been added
Use of this repository is without warranty and no responsibility for the use and any subsequent problems are accepted This is for research, development, and training quality, not professional quality. Like other functions, it has an Experimental Status.
This means that, under the Epic EULA, you cannot place anything Experimental into professional code. See Epic’s official statement
Publishing Limitations:
When a feature is experimental, users/players may not be able to publish applications with it or the feature may have limitations while in the experimental state.
No Backward Compatibility Guarantees: Epic Games does not guarantee backward compatibility for assets created while a feature is experimental, and the APIs for these features are subject to change
End of Legal Status for Epic GPU Lightmass and Luoshuangs-GPULightmass-5.6-preview Started 10th May 2025
This application is used to generate visualisations of a professional standard.
This does not need the programs to be official Epic code.
If you need more official information consult the Unreal Engine Fornite (UEFN)Terms and Conditions they are the same as the Standard Engine T & C
