Here's a solution if anyone runs into the following error.
I upgraded to a 1070ti from only a 1070 and Unreal threw this error. I tried first by adding GPULightmass again, but failed, so I just did a clean install.

UE4 Version: 4.21.1
Graphics Card: 1070ti

The simple fix was to completely "reinstall" GPULightmass. All I did to fix the issue was:

• Remove the "Binaries" and "Config" folders.
• Add any backed up "Binaries" and "Config" folders (aka CPULightmass)
• Copied newest version of GPULightmass back into the"Engine" folder to replace CPULightmass (this is the old way not using Situx's installer, either should work)

When in doubt, just turn it off and on again.

I got this on a fresh install of GPULightmass to 4.22.3 ... tried your above steps, not fixed ... have you had this come up again, where you might have had to solve it differently?

I've updated the Adaptive Hemisphere Sampler of GPULightmass's Brute Force GI Engine. Please redownload.

Also there are some screenshots of Brute Force (GPULightmass) vs Irradiance Caching (Lightmass, default production quality):
2min50s (GTX1080) vs 8min10s (i7-6700k), Simplified SunTemple
If you look at the timings only then it is not very impressive. However the quality has a big difference. If you want to tweak Lightmass parameters so that it prduces same quality images as GPULightmass then I believe it'll be at least 10x slower:





The downside is GPULightmass has noise while Irradiance Caching has 'built-in' smoothing. While a denoiser is definitely on the plan, I'm still working on the sampling algorithm to get better quality samples.

Edit 04/14/2018: I made some changes to the sampler to suppress the artifacts on the wall:

You're welcome!

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?

Would you like to provide your scene to me for debugging?

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.
