I’m struggling to get my Archviz scene to have good Lumen Scene and Surface Cache visualization, when using those modes. The scene looks otherwise good (I guess), in the viewport - but the dar Lumen scene and pink/yellow surface cache visuals are telling me something major is wrong. I have all relevant Lumen and GI settings correct, and I’ve tried all the individual Static Mesh adjustments, like increasing Lumen mesh cards and distance field resolution scale, without any noticable difference. Even a simple objects like the floor shows pink, even though it’s a separate object. I’ve watched every YT video showing how to troubleshoot this, by breaking large objects into smaller ones, but in my case I have so many small objects that still display the errors that I am at a loss on how to fix it. The file originally came from Cinema4D, then to TwinMotion - but does that matter, once it’s in UE5? Does anyone have any experience with trouble shooting this?
