Hello MEB, Do you have any suggestion regarding my additional question? My alpha channels are generated in Maxwell Render with the same format that the main image. Best regards Soundtraveller

Hello MEB, Thank you for your message. Your solution partially works for me. When I follow your steps, I am able attach the alpha channel to the layer. However, part of the alpha channel is clipped (a horizontal or vertical band) resulting in part of the layer not being displayed. Is there some formatting to be done? Best regards Soundtraveller

Hello everyone. I am new to Affinity so I apologise if the question has already been answered. My render software produces images/renders as well as alpha channels (black and white raster graphics). How do I copy an alpha channel into an empty mask layer? Thank you for your help Best regards Soundtraveller
