My photoshop file contains the following layers:
- Shape layer with a custom shape in it colored blue
- Shape layer with another custom shape in it colored black
- Solid white layer
There is no background layer.
Without rasterizing any layers, I'd like to make the shape in layer 2 create a transparent hole through the white layer 3.
When I export this to an 8-bit PNG, the end result should be a square white image with a blue shape on it and a transparent area where the background of a webpage will show through. No black would show in the image (unless the webpage background contains black).
I can do this by selecting layer 2, cutting that selection out of layer 3, and then hiding layer 2. But I'm hoping to do it in a way that leaves the shape layers 1 & 2 editable and not require extra steps to create the transparency. I want to just continue editing layer 1 and 2 and then export as PNG.
Is this possible? If so, how?
