Issues with Reflections

Hello All

I have been working on making a studio for an upcoming broadcast. As I have been working and tweaking different settings I have noticed that the only way I am able to get reflections from my billboard, as well as the screens in the space, is if I use Screenspace reflections. I have tried with Raytraced reflections, as well as planar reflections I am never able to get the proper reflections on the desk.

Screenspace Reflections

I have been able to minimize the artifacts from using screenspace reflections but was just curious as to why this is happening and how to avoid this issue in the future. Let me know if you need any more details

Best,

Have you made the required settings to the UE4 project (custom depth stencil pass, etc)?

There is also a setting in the Aximmetry Camera where you need to select using ray traced reflections. I would still recommend planar reflections though.

I did make sure that the custom depth stencil pass and the other settings were correct as well as the camera settings for the Aximmetry camera, and was never able to get reflections to appear. I also noticed that the dynamic material on the TV was showing the default material in the reflection when on Ray Traced reflections.

It is something I will investigate further after I get through the current broadcast with this set to see if it some something in the setup of the set or if it was something else that I had made a mistake on. For the purposes of this broadcast, I am not planning on using raytracing because of performance concerns and lack of time to fully optimize for it.

Oh, I see now why ray traced reflections aren’t working with the billboard. You need to enable “Include Translucent Objects” since the billboard is rendered using a translucent material.

Regarding planar reflections you would need to add a reflection plane right at the table surface, or it won’t reflect correctly.

Yeah, I was rereading the documentation with my colleague and we saw that as well. They are working nicely now. I was able to get it to work both ways and I think we are going to run this one with raytracing as even with the lower setting it still looks better. Thank you for your assistance.
