With a vast lighting, shading, and rendering toolkit at their disposal, artists and designers have full control over the entire creative process, from real-time look development to the final frame.
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.
