Question on creating Blurs from Alpha Channels after watching a PS tutorial

[Brammy]

Hi all,

 

I was watching this video on creating blur effects from alpha channels in Photoshop and I am wondering if it is possible to create a similar effect in Affinity. It looks like when they do the blur, they are targeting the alpha channel in the blur dialog box in PS.

Hi @Brammy,

I'm afraid we do not support z-maps for blur. Our blur can only be applied globally, and not selectively using a z-map. Sorry. 

Thanks,

Gabe.

Great, thanks. I thought that was the case.
