**Build Type:** Binary **Build version:** 4.18.0-3709383+++UE4+Release-4.18 The gamma for the user interface appears to change when console variable r.HDR.EnableHDROutput is set to 1. Doing the same thing in 4.16 does not have the same effect. Did not test in 4.17. r.HDR.EnableHDROutput is 0: ![220050-ue4-bug-hdr-0.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/1/3/d/13d3258dff6bf234fb2db2779438571defb306e5.png) r.HDR.EnableHDROutput is 0: ![220051-ue4-bug-hdr-1.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/6/0/2/6029a55df02e56f3fcab21a35c89412473d21eed.png) ---
