bottom one is the old exe renderer… not this new one… 
Think ur eyes are playing tricks on u. I see no difference.
Does this work on 4.16 yet??
The 4.16 version seems to want you to compile the whole game engine, no exe
I’m running 4.15.3 and this has no affect on my scene whatsoever. The UnrealLightmass.exe version from is 4.15.1. Is that the issue? Maybe my overall setup isn’t correct? I’ve got an HDRI mapped to Editor Sphere for my sky, and the same HDRI mapped to my Skylight. Is there another way I’m supposed to be doing this? Tnx!
I tried this yesterday with a very basic scene I made in 4.15 - set to 10 bounces and high quality.
It’s made a noticeable difference, I am getting overall a much cleaner and more realistic lighting, and the soft colour bounces are also a very nice addition.
Thanks a lot, !
can you put the 4.16 lightmass.exe on a filedrop?
*thanks
So this does not work on 4.16??
Check the first post, a 4.16 link was added.
Has your GPU version progressed at all?
anyone compiled it for 4.16 successfully?
I cant seem to run GenerateProjectFiles.bat correctly, crashes. even if I run it as admin.
EDIT: Solved it. In case someone else is having this issue I managed to fix it by installing this prior to installing Visual Studio.
I just grabbed the exe thats been added to the first post.
Excuse me, ask a question, I think I don’t understand this article multi-bounced sky lighting meaning, where it is set, or what part needs to be opened, and I want to explain it carefully. Thank you very much
Hello
i have change the lightmass.exe on my unreal engine v4.15.1
the result is better in comparison with my old lightmass.exe
i have a problem on the bottom of the boxes : there are too dark
the angles beetween walls are ok
how can i solve it ?
can you give us your BaseLight.ini, please ?
patrick
Those look like issues with the lightmap UVs or if the ground/cubes are intersecting a bit.
I haven’t modify the initial project file. (FarshidNaji.uproject)
can you give me a BaseLightmass.ini, please to use it on unreal engine 4.15 ?
Hello everyone, please HElP! i replaced the unreallightmass.exe with this one and now i can’t buid anymore!! i get this message:

Why isn’t this a standard feature :o Fixes so many problems with lighting / eye adaptation / lighting workflow / etc… Awesome work!
