Sky from transparent object in Subviewport bleeds into other scene

Godot Version



I have a Subviewport scene with 3d elements to make a 3d UI. This scene rotates as the player rotates to keep everything centralized. When I have a transparent object in the Subviewport scene, the transparency doesn’t make the object see-through - it just causes a section of the default sky to bleed into the Player scene. Is there a way to make the transparency work for the player scene, or is it best not to mess with transparent meshes in this scenario?
