4.21 to 4.22 - Reflections don't work in Standalone Preview or Packaged Build

Development Rendering

I’ve looked at other similar issues but had no luck with finding a solution. Basically my glass materials and my water shader doesn’t have reflections in the runtime or standalone preview, but looks perfectly fine in the editor.

I’ve tried deleting all reflection sphere captures, placing new ones, and building them but it doesn’t help. I’m pretty stumped at this point.

Bump- No one else experiencing this?

I attached a screenshot of the water material in my project to show what I mean. I’m still trying to reproduce it with a brand new project, but I don’t know what it could be the current one that could be causing this. Unless the issue occurred when it was migrating from 4.21 to 4.22.

Can anyone from Epic confirm whether this is a known issue that will be fixed? Seems like some others are starting to experience this problem.

I compared all light settings and config files and found the issues for my problem. I deleted the DefaultScalibility.ini and removed r.SSR.MaxRoughness=0 in DefaultEngine.ini. That might not work for everyone but check the following:

  1. Some light sources have additional settings now (e.g. rect-light) which have default values
  2. Check the “Config” folder in your project if you have new/different config files
  3. Compare settings within existing config files (Notepad++ has a compare plugin)

Thanks for the tip. Unfortunately it didn’t resolve my issue.

I checked the config files, and there’s already no entry for r.SSR.MaxRoughness=0. and no defaultscalability.ini in my project folder.

The only lights I have in my scene are the skylight and directional light. Appreciate it anyway though.
