Hey everyone!
Does anyone know if there is a way in Affinity Photo to lerp from one layer (or layer group) to another using a third (grayscale) layer (or layer group)?
As far as I can see, masking will not work, because even at 100% opacity, a mask will only show the white areas.
It should work like this:
Layer 3: 0% -> Layer 1: 100%, Layer 2: 0%
Layer 3: 50% -> Layer 1: 50%, Layer 2: 50%
Layer 3: 100% -> Layer 1: 0%, Layer 2: 100%
The grayscale information on Layer 3 should be used for the "speed" it shows Layer 2.
Bright areas should show Layer 2 first, darker areas should show Layer 2 when approaching 100% of Layer 3.
Best wishes,
Shu
