Affinity Photo v2.0.3 in Windows and Gradient mask how do? i tired most 

and i want control this time layer opacity (way full (other end) shows only layer and empty (shows other layers)). do gradient converted it mask goed black. and where is correct postion for mask layer for such se?

and maybe adjustment layer "power" beetween areas of image.

i finally get work way what i expect (masking layers needed done different place). is possible use gradient rectangle (for example or any other vector shape) as mask. i mean without making it bitmap. why this way wanted i can edit then it.

i found it rasterise mask works and i can still edit gradientv after this. one problem is bit hard found where gradient edited (i found but button is not most clear)
