Pattern Layer sampling doesn't tile properly when rotated

[Pierre Charpentier]

This is a bug fix / feature request.

When creating a simple pattern – like a 8x8 noise for example – and creating a Pattern Layer, rotating it by let's say 45° and scaling it by 800%, we can see discontinuities at the edges, where the pattern should tile. The bicubic sampling doesn't work across the original pattern's boundary, which defeats the purpose of creating a tilable pattern in the first place.

Also, it would be nice to choose the interpolation method and the boundary behavior (mirror, clamp, extend, repeat, etc.) like other apps do, like Blender when it samples a texture inside a shader.

Also also, it would be better if you allowed a higher maximum value for the Scale, 1000% (10x) is not a lot.

@Pierre Charpentier you could try this trick to get your seamless pattern to behave correctly! The best path forward is to use the Smart Object work-around. This approach involves taking your pattern layer—before you scale or rotate it—and turning it into a Smart Object. By doing this, you let Photoshop's core, robust transformation engine take over, rather than the Pattern Layer's more limited scaling method. Once it's a Smart Object, you can confidently use the Free Transform tool
(Ctrl T for the PC or Cmd T for the MAC) to rotate and scale it to any degree you wish, even well past the 1000% limit. The result is a flawless, maintained tiling across your entire image, allowing you to finally complete your projects without those distracting discontinuities.

@creative explorer  Thank you (not) for this ChatGPT answer that completely misses the point.

I'm not asking for a workaround on the user's part, but a fix to improve Photoshop which currently doesn't behave properly. I know how to do it, like I said I could just use Blender (you know, a FOSS alternative).

@Pierre Charpentier sorry, I don't use ChatGPT... But, whatever...good luck with Blender.
