Luoshuang's GPULightmass

hi @Casper_AP ,
I have tried this with error loging and the error is

<Error>
<Code>AccessDenied</Code>
<Message>Access Denied</Message>
</Error>

Looking at you initial entry you have not correctly set your path
If you type “pwd” and you will probably find you are at C:\ the root
under normal conditions users applications cannot make files there
type

*Make a directory path /c/Users/Owner/source/repos
The “Owner” is replaced with your username.
or 

 *Make a directory path C:\Users\Owner\source\repos*
The “Owner” is replaced with your username.

Using Windows File Explorer

either way you need to
$ cd /c/Users/Owner/source/repos

git clone into the directory as the readme explains
then run ./setup.bat to pull down dependencies
This error also ours when your path is long paths over 25 character is the often reason for an error

Hello @Jimbohalo10 ,
Thank you for fast response. Yesterday I downloaded the files and copied them over to my D drive because my C is quite full. I am not sure if I did the correct thing according to your response but this is what I tried today: I ran git CMD in C:\Users\User\source\repos (it already existed) Then downloaded the ue5Lgpu511 folder into here. Right clicked on it and used git BASH to run ./setup.bat Unfortunately the same error occurred. If I run setup.bat through the git CMD and cd to the folder, I get Aborting dependency updating due to unknown failure(s).

I hope it’s clear what I’m trying to say, and thank you for your time.

Hello,

I copied the git folder to D:\Program Files\Git and ran it. Then used it on the ue5Lgpu511 folder on the D drive. The same error occurred.
I don’t really understand why you are saying the drive says its missing? The error states it failed to download because the archive was using an unsupported compression method?

I wish the old installation method was back :sweat_smile:

Hi @Casper_AP ,
For the old method, for 5.1.1, its always been there.
Go into Epic Games Launcher → Library
see EpicLauncher download 5.1.1
on drive D:

The final version binary of 5.1 was infact 5.1.1
the binary files which are used to replace the original comes form
here.
jimshalo10/GPULightmass-patch-511: This is GPULightmass-patch-5.1.1 for Unreal Engine 5 Binary (github.com)

You just go to D:\Program Files\Epic Games\UE_5.1 and extract unzip the archive on top of them. Its a zip file does not require Git.

Latest 5.3.2 Binary Luoshuang’s GPULightmass

You just go to D:\Program Files\Epic Games\UE_5.3 and extract unzip the archive on top of them. Its a zip file does not require Git.

Somehow I completely missed that, probably because I was looking for 5.3.0 at first. Thank you for your time.

I can’t build solution LuoGPULightmass for Unreal 5.3.

It’s been a whole day since I am baking lights on CPU very bad results. But I come across this post and used files you have provided; I must say it’s literally took 3 minutes baking same scene (on GPU) and much nicer results Thanks, you saved my day. Now I can die in peace.

Hi @nickday,
Looking at the error log this is not errors from my repository code. Many people have used this 5.3 LGPU code. The code from LGPU 5.1 Cannot be mixed. I have hand code 5.3 code to work with LGPU at
LGPU 5.3 Git repo
The error suggest a missing file CookMeta.h


Line 42 of CookOnTheFlyServer.cpp

My code have the following at line 42 CookPackageSplitter.h
![noLGPU53code|610x356, 50%]
(upload://dMXRdAGMYj4YLcFzE7E3JWrfkNe.png)

I therefore suggest you archive your current code and use the repository link above.
If you want the original 5.1 binary got to post

ok thank you jimbohalo

Is the same bug present in the Epic GPULM (seen here: Epic's GPUlightmass - #481 by Arkiras ) also present in the 5.3 version of Luoshuang’s GPULM?

Hi Jumbohalo10, just a quick question, in ue5.4 your version there is not working quixel megascans? Or need to turn it on somewhere? Thank you
