This is good information as I'm FINALLY diving into Unreal Engine!! Thank you for this!
Thanks for the overview Jon! Your videos are super helpful and appreciated!
One thing that's been problematic for me recently is the aliasing/flickering effects that appear (visible in your video as flickering aliasing around the picture frame, camera highlights and keyboard as the focus changes - even the path-traced version has it). It manifests worst for objects in the background that are out of focus, tho thin objects also show this issue.
It's so bad in one of my shots that I simply can't use it. I've tried all the tips and tricks I could find online (maximizing all the Lumen Quality settings to at least 4, removing all Emissive materials, setting Indirect Lighting Intensity to 0, turning on/off TSR and other aliasing settings, switching from Lumen to Ray Tracing both in shadows and reflections, removing translucent nearby objects) but nothing seem to be making any difference.
It's almost like the lighting builds up in one spot over 100 or 200 milliseconds, then resets back to zero, causing thin highlights to flicker over time.
This also happens with Indirect lighting, which can be kinda hidden by lowering the Lumen Scene Lighting Update Speed and Final Gather Lighting Update Speeds, which cause it to flicker more slowly. But even these don't help the flickering edges of bright lights.
Do you have any idea how to avoid that flickering on the highlights on the camera, most noticeable in the Lumen and Ray Traced comparison shots?
Realy great question. I'm also interested in finding solution.
Do you use GI along side Path tracing? Confused on when to use it.
Does the GI setting for path tracing even exist anymore?
Could you help me in something, how do I do to remove the preview name on my cine camera. I can’t see when I’m on unreal using on it, it just appears when after on my videos
On my workspace i can find "standalone ray traced" in mt global ilumination. I got a rtx 3060, but i can find rat traced. Can u help me?
Ray traced was removed in 5.4 😭
@@JonJagsNee RIP did they just shift to lumen?
