Luoshuang's GPULightmass

Updated for UE 4.23.0-release.

Many Thanks Pax! very much appreciated.

Strange thing is; with 4.23 I need to revert to the original UE code or my projects crash on the Quest. Easily done with a simple bat file but still would be nice if that wasn't necessary.
Any GPUlightmass users who use the Quest who noticed the same?

Thanks so much man! Really on the ball with these updates.

Thanks for porting the GPULM to the 4.23
Just one problem: the start of bake blocks whole UE4 interface until the end of bake.
Could you check this problem ?

It's been like this since the first 4.23 preview. I don't think it has anything to do with gpu lightmass (this bug is still present without gpu lightmass installed)

Thank You so much for the quick supply!

I'm using 4.22.3 with the auto installer and I'm getting the following errors:

invalid device symbol

invalid texture reference

 no kernel image is available for execution on the device

Windows version: 10 64-bit
DirectX runtime version: 12.0
Graphics card: GeForce GT 755M

Any hints?

Did you get GPU lightmass to work on older builds? 4.21 perhaps? I would try to verify the engine and reinstall gpu lightmass. I want to point at your fairly out dated video card as the culprit, but it should work since it supports CUDA.

I'm using an iMac (Bootcamp). Older versions don't work as well. Reinstall doesn't work. Any specific setup you guys recommend buying?

[Sleeper.]

Where can I find the instructions for installing this? Or do I only have to extract the zip into the 4.23 folder?

Edit:
I've looked at the auto installer script, but I can't figure it out. Would be cool if someone could make a dummy guide for this, because I'd love to try it for 4.23.

Use this archive, and just unzip it into your engine folder (make a backup of the replaced files before unzipping, or do a "verify install" if you want to revert the changes)

Any decent current gen i7 or i9 Cpu and 1080Ti or 2080 if you want really good RTX performance. Plenty of ram for content creation. 32/64GB+

hi guys i have huge problem with 4.23.0 gpulightmass on yesterday. (binary version)

BUILD SUCCESSFUL for win64 but when i run the package exe i get this message. i did check RHI settings and setted dx12. (raytace activated project)

https://i.ibb.co/Mpmy0cZ/packerrror.jpg

Engine version verified and problem gone. A really big problem on gpu lightmass with 4.23.0 (even packaging successful but not working). please alert users/developers to this problem.

[fixe]

Is there any similar project that works on Unreal for Mac?

I can confirm I have the same problem with GPU Lightmass. Everytime I package the project I need to copy back original CPU Lightmass files.

Also using auto-installer from Situx isn't working for me - but this could be something on my side, not sure about that. After I edit BAT file (changing UE version and zip file with GPU Lightmass) and run GPU installation, everything is working. But after reverting back to CPU Lightmass, UE4 crashes and I need to reinstall engine. I think the installer doesn't backup all original files from engine when switching to GPU lightmass (had no problem in 4.20-22). But as I said, this could be something on my side and it's not a big problem, I'm copying files manually. But first problem with packaging is much more uncomfortable. Anyway thanks a lot for keeping GPU lightmass updating
