How to rotate Live Procedural Texture in Affinity Photo?

[Jung21]

Does anyone know how to rotate Live Procedural Texture in Affinity Photo? Or maybe it can be done with some equations?

Not a live one, no. The closest I can get is:

Create a Pattern Layer that fills your entire document. Enable Mirror and fill the layer with a colour. Apply your Procedural Texture as a 'baked in' filter, or Merge Down a Live Filter Layer, and the whole Pattern Layer can then be rotated along with the effect. But the filter effect is no longer editable. 😞

I think you could probably rotate the effect if you knew which of the many functions to use. But it's all a bit of a dark art... 😈

You can use helper objects to manually rotate the 4 corners.

1. create a square
2. duplicate
3. rotate as needed
4. create perspective filter so that it uses the square as reference for the nodes
5. rotate nodes manually to rotated square

you can stack multiple filters.

you can duplicate a filter of 10 degree rotation to get larger angles. 

another method to try: make 1 px line invisible in inherent mask. Now the filter can be rotated if the mask is non-primitive (all white).

Thank you @NotMyFault and @h_dfor reply and idea. Also i read at  @NotMyFault other post asking for more documentation of equation to moderator or developer but they also does not have satisfying answer.
