[RESOLVED! Thanks @LeeThorpe] Color Dodge blend -> bug? (vids & image inside)

[Affinity iPad Student]

I’m following this video, see how color dodge affected her clouds layer (timestamped video) and then see my horrendous result after:

 

So why is my color dodge doing this? 

 

 

Pretty much this ugly thing right here is what my color dodge is producing:

 

 

The color dodge in the video produced this:

 

 

Is this a bug?

 

this is my file:

I get the distortion with your file, however i don't when creating a new document and follow the same process on iPad and desktop.

Could you try this again from scratch to see if it re-occurs?

Unfortunately, the same issue, all my software is up to date: 

Troubleshooting I tried:

• rebooting ipad

• closed out affinity photo, then relaunched it

• deleted the previous project started from scratch (twice already)

• I have 2020 iPad Pro 12.9 with 14.32 gigs available 

 

iPad up to date:

 

Affinity Photo up to date:

 

How are you getting it done? on your iPad?

The step in the tutorial where she asks: choose render clouds via photoshop

 

affinity doesn’t have that, so I ignored that entire step and instead used my cloud brush on a new layer, and then put that layer on color dodge blend. Could it be my cloud brush preventing color dodge from doing it’s working? (I included brush file in this post)

 

New file here:

brush I use for cloud (courtesy of Rikard Rodin’s, Nucly youtube channel):

Hopefully we figure this out, I love this effect, and would love to replicate it.

Ahh, try using Filter > Noise > Perlin Noise.  to generate clouds.

Essentially this is a noise generator that looks like clouds, except unlike Photoshop, you have various controls over the noise.

See if you have the same issue following that step.

Thank you @LeeThorpe

 

Perlin Noise was the answer, I did not achieve her look. Notice in the image below, she has some huge gaps of black in there, thus… achieving the look of a colorful space nebula:

 

 

 

This is my result, notice the much tinier black gaps, making mine look like colorful sand grains:

 

 

I tried playing with the octaves, zoom and persistence, but to no avail, that said, I’ll tinker around and hopefully come up with the space nebula. Consider this resolved! Thanks again @LeeThorpe
