Thank you pax invictus!

I'm getting the same "Array index out of bounds" error as some other people here - did anyone figure out what's going on with that?

I always get that when trying to build a scene with one or less static things. Like a static mesh with no static/stationary lights. Or a static light with no static meshes etc.

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)

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+
