Mockups for Smartphone with multiple layers
Good morning, first time posting here, id like rto ask a question that i'm sure has a very simple answer but would be very grateful for any advice/guidance.
I have a file containing several layers which have different views of a smartphone.
We use these to showcase phone cases on the latest smartphone devices.
I vaguely understand how to create a mockup on the indivdual layers however I know there is a way to have one master layer which will have a 'Artwork goes here' layer that will then apply to every individual layer and the various different views of the phone case will all have the artwork correctly showing having only had to upload the one file to the main mockup layer.
So, now i have struggled to explain that as well as i hoped, can anyone shed any light on how to achieve this please?
I have attached some images showing the various layers I have to work with, and than two further images showing the Add Art Here layer and the finished artwork and what i require, hope to achieve, hope this makes sense.
