Description

As reported on UDN.

If using a custom postprocess which replaces the tonemapper, FXAA doesn't work.

Steps to Reproduce
  • Make a simple custom postprocess material which replaces the tonemapper
  • Create a test level
  • Add a postprocess volume with the postprocess material as a blendable
  • Disable temporalAA (e.g. with showflag.temporalAA=0). Notice that antialiasing no longer works
