Render to depth Aximmetry 2022.5 + UE 5 problem

Studio Operators Bugs Editions Composer 2D Compositing Video Recording Virtual Camera Unreal

 

Hi everyone!

Since I changed to version 2022.5 and work with virtual camera I have had problems with reflections on the floor and walls. I have noticed that if I turn off render to depth the blur effect behind my billboard disappears but I have giant reflections and they are not mirrored so it doesn't look real. Has anyone had these problems? How can I solve that? I have read the one about custom depth but I know that it is for objects that are in front of the billboard.

IHope someone can hellp me with this. Thanks in advance !

The reason you’re getting the blur around the billboard is that you’ve set the focal point beyond (or in front of ) 3D the position of the billboard. If you set it to a reasonable value you won’t get any blur artifacts. If you need more blur on the background, move the virtual camera further away and zoom in instead.

@twentystudios Im sure my focal point is not the problem. As you can see the reflections below the talent with and without RTD are not displaying correctly.

I’m saying that you should keep Render to depth enabled. You said you were getting blur around the billboard with it turned off, and I explained the reason why you were getting the blur. Without Render to Depth you can’t get accurate screen space reflections.

For the other example, it looks like the billboard isn’t aligned to the floor plane in 3D space and isn’t casting reflections from the right perspective. Aximmetry recommends using planar reflections for the floor where the billboard should reflect and clearly warns about using screen space reflections in the documentation, so try that first. 


Keep in mind that you’ll never get realistic reflections from object like a chair, since the reflection is actually cast from a 2D image. You won’t get individual reflections from the legs on the chair and no reflections from the underside of it. This isn’t a limitation of Aximmetry, it’s simply a limitation of compositing a 2D plane in 3D space. The correct way to get realistic reflections is to put a clear plexiglass reflective surface on the floor of your green screen instead.

Hi Walter,

Hope you manage to solve the blur on the reflection based on TwentyStudio's guidance. If not, feel free to ask more about it.

Warmest regards,
