Ray Tracing Translucency Issue

I have the following issue when activating Ray Tracing Translucency:

It happens on all my maps/project when I activate RTT and preview it in PIE. All other RT features seem to work fine.

I have a RTX2080,latest video drivers, Engine 4.22.2, using -dx12 -raytracing flags to launch the editor.

Anybody else having this issue, or even better, does anyone know how to make it go away?!

Thanks for the suggestion. I am indeed inside a ball… I am simply using the free camera to navigate in PIE. The ball I believe is the collision for this default camera.

So I have two questions:

Why does it only show when I activate RTT?
How do I get rid of it?

Any thoughts?

I have tried raytracing (I don’t have ray tracing card so I’m not sure how it work) but interesting part is there are differenet shaders (materials) for ray - tracing. (They have to recomplile again - And it changes with settings.) I didn’t had any problem with that but maybe there is some problem or it’s not compiled (yet)?

I don’t think it can be collision. you can check what is this by clicking in hierarhy in editor.

It’s perfect for debuging. If you still don’t see try disabling this collision, meshes… [Whatever is here and can be displayed]. try untill you find issue.

Maybe switching view in editor to collison will help?

This is what I see when I eject. It isn’t a material compiling issue. All materials have complied. This ball is always present (since I can remember in UE4). It never normally appears expect you can see it in PIE when you switch to another scene camera for example in Sequencer.

I just don’t understand why it shows up and is causing this issue when I turn RTT on… it’s crazy.

Ball doesn’t have material. What pawn are you using?

You can simply disable rendering in options of static mesh and it will do the job. (And maybe collision if enableD or it will be double as there is collision component)

I have not changed any of the pawn settings, it is simply the blank map that opens up when you start the editor. I do not attach that ball to the default pawn, it is always there in PIE and Viewport. It never used to be a problem but is when RTT is activated.

Once ejected, I can clear the static mesh from the default pawn - but I want to know why I have to do this in the first place?

Ask Epic team. I don’t know answer to this. You can report this, it’s bug for sure. I have told you a workarround.

ray tracing is kinda new so bugs obviously happen.

Thanks for your help, I can at least view my scene in PIE now!

Hey,
Seems like you are in some other ball with not compiled material. Watch slowly.

To make sure:

Run game in editor not separate window (Did exactly same thing happened?)
Eject from pawn and see what happends…

Comment what you saw.

If you will use some character then you shouldn’t even care about this, as this shouldn’t happen to character you create.
