Strange 2nd incorrect billboard reflection, goes black when render to depth turned on.

Hi All,

Anyone know what this reflection is? I have seen similar ones in other posts but have not yet been able to find a fix. When render to depth is on, the billboard reflection is good but has a black smudge untracked reflection behind it. See photo 1

When render to depth is turned off, I can see the other reflection artifact. see photo 2. Hopefully someone has encountered this problem and can give me some tips or troubleshooting steps I can take.

Many thanks

What type of reflection are you using? Lumen, Screenspace or raytraced? If you’re using Lumen, do you have Hardware Raytracing enabled, and have you enabled High Quality Translucency reflections?

Hi thanks TwentyStudio you have saved the day again!
This has fixed it (I swear I tried this before). Perhaps I had Raytracing Translucency enabled? I am not sure. Just for clarity in these are the steps I took:
In the post process volume I selected Lumen under the reflections section. I unchecked all the other reflection processing (ss, RT) options. I made sure RT translucency was unchecked also. In the project setting I made sure I had Hardware Raytracing enabled checked.

Amazing, thanks again.

p.s.

I noticed I have no option for High Quality Translucency.
For reference I'm running unreal for ax Version: 5.0.3-0+++UE5+Release-5.0.
