How to fix noisy reflections?

I tried fixing the reflections on my emissive white tile material and the reflections are noisy at a certain lower angle but seem to be ok when view over the top of it. The reflection also has a weird outline around my character at certain angles too as shown in the 2nd screen shot. My reflection method is set to Lumen and I’m not sure if it is a project setting that might be causing it, my material or if it is a limitation with my hardware. Any advice is appreciated.

Hello there @TypeFinalMagic!

Checking around the community, there have been a few threads regarding Lumen reflections not working as intended, lately. Some of the methods to deal with the issue go as follows:

  • First of all, please ensure your OS and video drivers are in the latest version available

  • Test disabling Nanite for your reflective meshes

  • Disable hardware ray tracing as well:

  • Go to Project Settings > Engine > Rendering, and look for the Reflections option. From there, increase the resolution value to improve reflection quality:

For more options to improve your Lumen reflections, I suggest following this guide.

Hi. I followed your steps.

  • I updated my drivers
  • Nanite was already disabled on my tile cube meshes
  • Disabled “Support hardware ray tracing”

I changed the reflection capture resolution but it did not appear to have an effect.

I went and changed my reflection method to Screen Space and it look less chaotic and slightly less noisy compared to the Lumen reflections. I’m still trying to figure out how to smooth out the screen space reflections. Though after changing to screen space reflection, my water material/pool area started shining a green light now at certain camera angles (See 3rd screenshot). I’m not sure what the cause of that is yet.
