So, recently i upgraded my lightroom to the up to date version 2021, but i'm struggling to find the buttom to export multiple images from lightroom to layers in photoshop so i could make a stopmotion in photoshop.
It will be necessary for you to first export the images to a folder on your hard drive and then open those images directly in Photoshop. It cannot be done from Lightroom. It is only possible to open a single image directly from Lightroom to Photoshop. It is different when using Lightroom Classic.
