GPU lightmass shows a poor quality than CPU

[michaelmonte]

What’s up guys.

I’m working in a project and I just realized that my Epic GPU ligthmass shows a poor quality than CPU lightmass. I’m using the 5.3 version. I got two screenshots to show you how strange de epic gpu lightmass is. You guys have any ideia what hell is going on? My cpu quality was set at medium and still is way better than GPU lightmass.

Thanks in advance.

Hi @michaelmonte ,
I have replied to a similar problem in the post
GPU Lightmass gives completely broken results in 5.3.1

Epic's GPUlightmass

If anyone doesn’t want to go through the hassle of building their own copy of 5.3 from source with the 5.4 fixes for GPULM, I compiled a binary installed build, which is a 10GB download and 25GB on disk. I’d be happy to share the link with anyone that needs it.

The main problem in Epic Lightmass has had some bugs and thats why we are still using Luoshuang’s GPULightmass - #2489 by Jimbohalo10

Thank you for your reply. It’s curious how epic broke the GPU lightmass in 5.3, cause in 5.1 version seems to be working well so far.
