My case is:

  • only one 3d model + 3d camera + active post process FXAA on that camera + active render texture for that camera, then use sprite to display render texure on UI.
    With change FXAA to TAA, I got different result:
  • FXAA => black background around 3D model.
  • TAA => transparent background around 3D model.
    So, I wonder how I can use post-process FXAA without black background.

I only want to show the cube, not the sky box.

Sure, Iā€™m inquiring with the engineers to confirm the issue.

FXAA is typically not used together with translucent RTs as it will make the translucent parts appear black.
