Alenknight Posted April 22, 2018 Share Posted April 22, 2018 Ok, i’m Going nuts about this. It’s a very basic question, and i can’t believe i’m Confused on this. I have 2 layers. I go and pick on the top layer.... new layer mask... i pick paintbrush... then make sure it’s black.... with all the max colors/resolution/thickness... everything 100%.... and it’s not painting. I’ve been trying this for 2 weeks... watched tutorials. I’m so confused what i’m Missing. I come from a photoshop world.... you pick a layer mask on top a layer, grab a paint brush... and paint. What’s so complex? Yet in ipad affinity... it’s JUST NOT PAINTING. I’ve rebooted, i’ve Tried on multiple iPads.... what on earth am i missing? Obviously i’m Frustrated... at myself more than anything... if you can, help. I really have no idea what i’m Missing here.... Quote Link to comment Share on other sites More sharing options...
Alfred Posted April 22, 2018 Share Posted April 22, 2018 Welcome to the Serif Affinity Forums, @Alenknight. 1. What brush are you trying to use? 2. Do you have ‘Opacity’ and ‘Flow’ at or near 100%? 3. Do you have ‘Protect alpha’ turned off?

exploremoar Posted April 22, 2018 Share Posted April 22, 2018 i was having this same issue and then realized it was because i had protect alpha turned on...side question what is the purpose of protect alpha? Quote Link to comment Share on other sites More sharing options...
Alenknight Posted April 22, 2018 Author Share Posted April 22, 2018 Ugh... it was the stupid protect alpha! Thank you so much.... can’t believe i didn’t see that.... why on EARTH is that ON by default!?!?!? Exploremoar... i can’t speak to affinity... but in PS.... alpha channels are various color and greyscale channels. You might want them locked so that when you make edits in a mask ... only certain layers or channels in the color spectrum are affected... you can isolate your greyscale edits. (It really should be off by default) thanks again everyone! Quote Link to comment Share on other sites More sharing options...

You'll be familiar with RGB meaning red, green and blue channels. The alpha channel is the fourth channel of RGBA and it's used for opacity in Affinity and many other apps. Thank you! Do you think you could provide a real world example of when someone would use this feature? Quote Link to comment Share on other sites More sharing options...
