Isolated VFB Bloom and Glare FX Pass – Quick Tip

If you use the VFB to create bloom & glare effects, but also want to be able to manipulate it as a composited element, then here's a quick trick to create an isolated effects layer.

  • save the normal rgb pass, without the effects
  • save the rgb pass, with the effects added.
  • combine both images in photoshop, with the effects layer on top.
  • the the top effects layer blend mode to “Difference”
  • create a flattened copy of the layers below [Shift+Opt+Cmnd+E] (on mac) – this is your isolated effects layer. Set layer blend mode to “Linear Dodge (Add)”
  • to test that it works as intended, turn off the rendered effects layer below. Now you can control the isolated effects as a separate layer in a multipass composite.
