solved

I am dragging way too much rectangles to fit the artboards dimensions in designer or to fit a canvas in Photo.
Draw a rectangle with the rectangle tool and then dragging the corners to snap to the artboards or canvas corners does work fine but it just takes too long. Is there a quicker way or a shortcut I am missing ?
Something like "fit to artboards size" or "fit do canvas size" ?

Good question, because an artboard being actually kinda hybrid container/object thingy, it can have a fill on its own!

Except for #1 & #6, the rest of this workflow should work 100% with keyboard shortcuts. You may need to assign some of them first, that is…
select the artboard object – e.g. click on the artboard name on the canvas with the Move tool Edit > Duplicate – duplicates the artboard in place incl. content Layer > Hide – hides the duplicate artboard temporarily because: Select All – selects now only the content of the visible artboard Edit > Delete – see above click on the name of the empty artboard to select it again Layer > Convert Artboard To Object – a rectangle! optional: Layer > Arrange > Move To Front (or forward, whatever) Select > Previous (or Next, depending on #8) – selects the hidden artboard Layer > Show (or Show All if it was the only hidden object) If you have an external macro utility, you can automate steps 2–5 and 7–10 as a keyboard shortcut sequence.
On Mac, that would be possible with Automator and AppleScript via System Events (the only method to script Affinity at the moment). Even easier with nifty macro utilities like Keyboard Maestro.

In AP, have you considered using Fill layers for this instead of rectangles?
Also, why are you filling artboards or canvases with rectangles? 

Looks like I triggered someone ;)

Hi,
nice to meet others with similar mindset of trying impossible things, or do possible things with the wrong tool (Photo).
The most capable tool in principle for this challenge is procedural texture filter. Unfortunately, it currently lacks most color format conversions, even basic RGB to HSL must be done with basic math. (I have these ready to share if needed).
I think a simplified version of your target “result” using a triangle shape might be practical.
general steps:
convert from source color format into LAB (assuming LAB is good enough approximation) define equations to clamp colors on the 3 sides of the triangle (stored in temp variables) If you could provide the equations for the 3 sides of the triangle this would help Use sign() function as helper for if/then/else decision trees to combine intermediate results Looking forward to collaborate in this challenge

Try using a Soft proof Adjustment layer

Just guessing...
It looks like he uses texture, grain and some airbrush brushes in pixel layers overlaying the actual vectors to achieve that look. At some parts the vectors could be rasterised and then further edited (blurred, smudged etc.) as pixel layers to get rid of that "vector look" you mention. 

The 1.9.2 update fixed this. Many thanks...

You could try it with Blend Ranges...
 

Hi @BRlombardi,
Unfortunately the Affinity Brushes Studio doesn't currently support Subcategories, although I can certainly see how they'd be useful.
I'll move this thread to the Feedback section of our forums, for our devs to see and consider adding in a future update!
I hope this helps

Yes, thats a good idea. Gonna go with this, saves me a lot of time...
Thank you, that helped me a lot.

Updated today to 1.9.0 and the mentioned issue is gone. AD feels as responsive as it was before. The update solves the problem.

Hi Dan, sure:
I have two separate Folders added, each of those has a few folders inside. -> Folder/Folder/Template Files
