The system lists all required materials with the available quantity that Keyline found in the calculation. These are e.g. Wire-O loops, staples, glue, cardboard boxes, etc..
Here you can manually make a selection for each scale.
Keyline does duplicate this selection completely. This means that you do not have to select the material again for postproductions.
If you offer several echelons and want to select the same material for all editions, you can use the arrow button to the right of the dropdown to apply the selection to all echelons.
