I’m having a similar issue with Swarm to what some others described a while back, but their fix doesn’t seem to work. I’m on 4.24.3 using the 4.24.3 version of gpulightmass as posted a few pages back. I’m using 2 machines; both build locally, however when using Swarm it fails.
My local machine is set to avoid processing locally. The swarm starts up correctly, the build runs seemingly to completion on the remote PC, but then something fails and my local machine starts the build all over again. When it fails it spams the same error several times;
I also get the classic “failed to send back log file through swarm”.
I’m pretty sure I’ve had it working with test scenes (I’m at the 'questioning reality’ stage of troubleshooting) but as soon as I try to render a real one I get that error which seems to then permanently break the process; levels which worked before fail in the same way. I’ve tried all the swarm troubleshooting tips I could find, including clearing cache folders and sharing the cache and project folders over the network. The latest attempt at a fix was completely removing Unreal engine from both machines and trying again from scratch; nada.
Need help! I’m using UE 4.21.0 and I baked the scene using GPU Lightmass - everything works perfectly.
But when I tried to use UE versions 4.22.3, 4.23.1, 4.24.3 with GPU Lightmass for these versions I have a problem. When I baked a scene using GPU Lightmass - maps baked - but when I save the result as a new level everything is lost!
+1 for the 4.25 version. Tried to stitch it together for a compile, but too many errors to fix without actually knowing what files I need in order to compile it properly.
That looks correct to me. The floor and walls are super reflective, so the red color from the floor bounces all around. What do you get with the path tracer? RT is not ground truth and I wouldn’t trust RT GI too much.
I’m fighting against Gpu lightmass using HDRI. I always gets fireflies and not so sure how to avoid it. Lowering FireflyClampingThreshold making lighning gets awful
I don’t know who you are. I don’t know what you want… but what I do have are a very particular set of skills. Skills I have acquired over a very long career. I will look for you, I will find you… and I will love you.
Seriously tho, thank you for the incredibly quick response!
Try bumping VisibilityNormalOffsetSampleRadiusScale in BaseLightmass.ini from .1 to .5 (that’s what I was told, I haven’t tried it since I am still on 4.24)
