How to Fix Billboard Halo Effect with Depth of Field in Aximmetry

I’m using Aximmetry for a talk show-style virtual set, with Unreal Engine providing the background composition. I want to keep the billboard (keyed talent) sharp while using Depth of Field to blur the background, but I’m running into an issue in Aximmetry where the edges of the billboard bleed into the background blur, creating a halo effect. I need to keep virtual cameras on because the lighting interacts with the set better that way. Has anyone had this issue, and how did you resolve it? Should I fix this in Aximmetry, or do I need to adjust something in Unreal? Looking for simple solutions!”

The blurred halo around the billboard is the shadow and reflection casting copy of the billboard that is rendered behind the sharp billboard. If it’s blurred it means you haven’t set the focus plane correctly. Unreal emulates a physical camera including the depth of field, so you need to set the focus where your foreground (the billboard) is sharp. If you want a more blurred background you need to change the camera position and/or parameters, just like you would with a real camera. A lower aperture (like 1.2) will give you a more shallow depth of field . The easiest solution is to just move the virtual camera back and zoom in, again just like with a physical camera.
