Separate Alpha Channel

Artistic Support Lighting and Rendering
1

Hi

  • PNG
  • RGBA
  • Film - transparent

-> This way I get my object cut out from the background. That’s OK.

BUT
I actually want the alpha channel as a seperate channel/file. So I can adjust it in Photoshop. How do I get this?
Check this image. This is the alpha channel of my render. I get it by clicking that icon. But I don’t find a way to save this …

Use Nodes. Separate RGBA, connect A to Output.

Or just extract the alpha layer in Photoshop.

Gonna try this with nodes because there is no alpha channel in Photoshop.

Thanks, worked.

or you could just select the alpha layer in render layers?
