[UE4.12.4 MAC] SSR Quality above 60 not working

anonymous_user_389e656c · July 8, 2016, 9:23am

In 4.12.4 on mac setting the SSR quality using a PP volume does not work as expected.
Setting a value of 60 or above the reflection gets inconsistent, there’s a lot of shimmering, and there is no visibile change with any value between 60 and 100.
Any solution?

Quality 50:

Quality 60 or above:

Hello devel.bmad,

Have you checked to make sure your Engine Scalability Settings are all set to Epic?

Do you have reflection capture actors in your scene?

Are you building using Production quality lighting, or are you using the preview quality?

I will test this issue soon and wanted to gather a bit more information in regards to your scene set up, and the settings you have applied.

Let me know if you have further questions or need additional assistance.

Cheers,

Have you checked to make sure your Engine Scalability Settings are all set to Epic?

Yes, all to Epic

Do you have reflection capture actors in your scene?

Yes, and the same scene on a windows machine seems to work properly (even though I don’t see any changes in the effect between 60 and 100 even here)

Are you building using Production quality lighting, or are you using the preview quality?

Production quality. The issue is directly visible in the editor.
Please let me know if I can provide further detail.

Thanks for checking to make sure those settings were applied appropriately. I was able to confirm what you are reporting and have entered a bug for this issue, UE-33072.

Once the issue has been addressed by our engineers, the fix will be added to the release notes for fixed issues within an upcoming full engine or hotfix release.

Let me know if you have further questions or need additional assistance.

Update: This bug was returned as Won’t Fix. SSR has only 4 discrete quality levels. See r.SSR.Quality. The slider just picks one based on certain threshholds. We aren’t likely to spend time improving this at the moment. You can use the console command ‘r.SSRQuality ?’ to get a better understanding of the quality levels. Be sure to have the output log open in order to view the information.

Cheers,
