Repeat Pattern tiling Issues?

[Sarahreneee]

Hey there affinity crew, there seems to be some issues with my pattern repeat ONLY on a larger canvas..? I’ve already troubleshooted my pattern block and it seems to scale fine on smaller canvases, but I need a larger file size for a particular project. Am I doing something wrong  or is this a bug?

I place the pattern tile at the largest possible scale first, then rasterize, then create new pattern layer from selection, then scale down. Like I said it works just fine on a smaller canvas size. Also the original file is 4000x4000px, so still bigger than the overall canvas sizes

 

I’ll include pics on a smaller canvas (correct scaling, no thin lines) and the larger (tiling occurs)

This potentially creates semitransparent edge pixels, depending on scale factor. Those will shine through as light lines / seams.

please check the layer size and position to be whole integer / no fractional non-Zero digits - after every movement or scaling.

try another rasterize & trim before creating the pattern layer. But this will note heal any transparency - see next reply.

i cannot spot the issue in the PSD files you uploaded.

please upload a afphoto file (saved with history!) where the issue is visible.

Here ya go thank you! I included another where the issue is more obvious as well

I would recommend the to do any scaling only on the pattern layer, not on the source files.

The way you do the scaling currently creates semitransparent edge pixels. It is far to complicated trying to heal this later. Please ensure (check with channels panel on alpha, or zoom in and use pixel grid that no semitransparent pixels exist. below an example. The size is 2476x2475, so 1 px to large in x direction. The edge pixels exist has very low alpha value, but not zero. You may cut it off simply, but the pattern would get slightly distorted. 

Where did you get the sunflower tile from? Any chance you get this in a true pixel format like jpg png tiff instead of pdf / eps?

To cut the excess pixel off:

1. create a rectangle of 2475x2475px, having whole integer position. No fill, no stroke
2. nest the source tile into it
3. position to start at top left so the excess 1px edge gets cut off
4. rasterize and trim rectangle

you can then use the corrected source tile for patterns.

I'm no expert on surface pattern design myself, but I have been told that, when resampling, it's important to use the correct algorithm to avoid lines like this, I think Nearest Neighbour was mentioned. Whether or not that may help in this case, I have no idea!

@Sarahreneee I looked at your afphoto files, found what appears to be the tile you’re using, copied it into Designer 2, and tiled it there.  In my opinion there is definitely something wrong with the edges of the tile.  I get the lines you complain about no matter what I do.

I don’t use AFPhoto, and can’t advise you on that subject.

I make patterns in AD2 using only the vector capabilities, did way too much raster work in Photoshop.

In the hope this helps you in constructing patterns, I strongly recommend keeping your decorative elements (motifs) and backgrounds (fills) on separate layers, and ensure ALL your decorative layers are above ALL your fill layers.  This will prevent a fill layer from covering a decorative element that if lower down in the layer stack.

I reconstructed your pattern in AD2, files attached (from iPad).

Yes, I do have and original png file for all my pattern tiles. Problem there is when I place those, a current affinity bug isn’t processing the colors correctly 🙄 it imports all washed out. My “workaround” has been to import as a pdf (the whole purpose is to create my own mockups).

I don’t “scale” the source file per se, I’m just placing it to at least snap to the edges of my canvas so I can start with the highest quality to make my pattern layer with.. just place, rasterize, creat pattern layer.

I won’t lie, I’ll have to read your response a few times to wrap my head around it 🥵 just was hoping there was a relatively simple explanation to the issue lol

 

I’ll attach the png tiles though!

Hey there, thanks for taking the time! It’s interesting you’re having issues in ad2 with the tile. I never illustrate my patterns in AD because I’m wanting to work with raster files for those, not vector. (I know there’s the pixel persona but I prefer illustrating in procreate)

So I make all my designs in procreate, and pattern test them in procreate and on an online tester before I export and use them. At that point they’ve been proofed so I prefer a flat image

Then I’ll bring them into AP2 to create the pattern layer so I can place them on mockups and use Photo’s displacement (texture correction) abilities. I really have no use for designer in this particular process

Thing is, EVERYWHERE else I use the pattern tiles (print on demand design studio etc) they work seamlessly. So I know it probably seems like a silly mistake on my end, but I know for sure there’s no issue with my tiles. Plus like I said, if I try the same exact process on a smaller canvas, there’s no issue 🤷🏻‍♀️ weird I know

It is more likely an issue of Affinity creating the PDF version. Could you provide one original PNG, and screenshots or a vibrio of the conversion from png to pdf? There the issue happens.

Can you use e.g. tiff or any raster format except PNG? When exporting from procreate?

@Sarahreneee  Well I don’t know why your tile behaves as it does, can only imagine your frustration.  I know about some online design studios, but I had no idea there’s a whole cottage industry vying to “test” your tiles. I would never trust them, no matter the promises and protestations, I’m certain they’re not doing it out of love…..

I’ll be watching to see if you report back on what you find in case I can learn something.  I’m disappointed with Affinity’s bugs and how long it takes to get them fixed.  I’m not tempted by Procreate, but I do keep an open eye on other possibilities.

I wish you all the best, good luck in this new year.

I could, all it is though is exporting finished artwork from procreate as a pdf instead of a png. No conversion 🙂 

Yes I could! I’ll try that. I always forget about tiff as an option because I don’t fully understand what its purpose is 😆
