Notes
Presets are a powerful feature in Enrich that allows you to try out a plethora of looks on your render in just a few clicks. While Enrich addon comes with a set of default presets, it also allows you to install your node groups as presets which can later be used just like any other preset.
To install a custom preset in Enrich:
Start by creating a node setup in the compositor of your desired look.
Add the nodes of that look in a new node group(CTRL+G for creating a new node group from selected nodes).
Make sure this node group has an 'Image' input and an 'Image' output. This is required for every preset in Enrich.
Add additional inputs to the node group. These will be used as the preset settings in the Enrich panel.
Once the node group is created correctly, select the node group, open the sidebar(or properties panel) by pressing 'N', and go to the 'Item' tab.
In the 'Item' tab, 'Enrich Custom Preset' section can be found. This panel will tell whether the node group can be installed as a valid Enrich preset.
Once all the conditions are met, click on the 'Save as preset' button.
A popup appears. Enter the name for the preset and click on either 'Generate thumbnail' or 'Choose thumbnail' button.
'Generate thumbnail' button would generate a thumbnail for the custom preset automatically.
'Choose thumbnail' button would open the file browser where a custom image can be selected for the thumbnail.
The preset should now be installed 🎉
