DUPLICATE OR USE A PRESET product/Look by selecting it, then clicking 'duplicate' and following prompts. This works well with 'presets'
EDIT product/Look data, colour, mask, active (use camera to test). Edits appear realtime but don't affect anything until you click 'Save'
DELETE a product/Look by selecting it and click the trash icon in edit tabs
EDIT LOOK MAKEUP via editing the individual products separately. You could have multiple windows open to edit products while viewing the combined Look
EDIT LOOK ASSORTMENT in the Look's edit tab go to Makeup> Products, and click "New", delete, or edit the list
You can add multiple product shades from the same category to a Look. If you do the last one of that category added (at the bottom of the product list in the Look) will be the one to appear on a face when viewing the virtual makeup. However, you can manipulate which products are displayed in UI vs what is used for virtual makeup using the 'Visibility' settings in each product's Info tab. Click the link to see use cases and how to's.
The example shown is the same look with 2 eyeshadows in it.
