Old youtube tutorial: VFB Regions and History
Notes:
- Starting from Corona 12, the new VFB 2.0 is the new default VFB in Corona, featuring an updated interface with improved user experience. For a complete overview, refer to the official documentation.
- In VFB 2.0, it is possible to compare images with different resolutions or aspect ratios.
- VFB 2.0 provides two options to open CXR files: by using the history tab or through the drag-and-drop feature. Click here to learn more.
The built-in history allows saving of multiple snapshots of the rendered scene (including region renders) and performing A/B comparisons directly in the Corona VFB. This allows quick comparing of different materials, lighting, or render settings.
To save a snapshot, click on "Store Current VFB" button.
To mark a snapshot as "A" and have it displayed in the VFB, left-click on it.
To mark a snapshot as "B" and have it displayed in the VFB, right-click on it.
To unmark snapshots, simply click on it again, or click on a different one to have it replaced.
VFB History can be used to store multiple "snapshots" of the scene, which can be compared.
