Yeah actually I went back and checked and ray tracing wasn’t enabled. Those shadows disappear if I get too close and look a bit noise from close to mid range. beyond that you can’t tell too well that their noisy. I believe specific features utilize ray tracing techniques to perform their functions but I’m not real sure. It’s not that big of a deal, hopefully they can get the bugs worked out of Lumen and make it a bit more performance friendly by the time UE5 is officially released. Right now as it is I have noticed shading artifacts pop up on the landscape material in specific situations. I believe those artifacts have to do with issues directly related to how Lumen works with Runtime Virtual Textures, so maybe it’s a bug they will eventually fix. I should mention I am using UE4 in the above project I was just bringing UE5 and Lumen up because these shading issues aren’t anything new to the Unreal Engine and seem to persist even in the Newest versions.
