Hello
Former photoshop user, I'm just starting with Affinity Photo.
I do Archiviz images from multi passes layers rendered from a 3d program, mixing / comping them onto a picture of the real location. One think I'm used to do is rendering B/W images of the objects also named Alphas. As those are pixel layers, I need to use them as masks to hide parts of a layer and reveal what's beneath. I tried with the mask to below fonction but there is no transparency in my pixel layer even thought the mask seems to be applied correctly, I can't see the other layers below.
I'm sure It must be something simple...
Thank you!
