TM 2025.2 Lumen Surface visualization

I’m testing out the Lumen in TM 2025.2, but the “Lumen Surface” display option (using the dropdown from upper right corner, where the eye icon and the full-screen button also are), and there seems to be no change in what is displayed. How can I check my Lumen scene?

You’re certain lumen is enabled and working as expected?

sorry - I had just posted a reply, using screenshots from UE5 settings. Basically having the same problem there, LOL - but that’s for another thread…
I will post up my settings from TM…

ok, so new I get the Lumen Surface Cache visualization working!.. but as expected (and similar to how it looks in UE5) I now have tons of black, pink and yellow errors


Is that more problems than you expected?
