that's nice, simple and useful, there's a lot function of procedural texture to try but lack documentation and example of this powerful filter, need more procedural texture tutorial
Thank you! x: x-position, y: y-position, h:height of document, w: width of document, rx/y: relative x position. They are fixed variables available in the formulas in Affinity. Hope it makes sense :)
In the description you mention dx/w and dy/h, I think you meant to write rx/w and ry/h. I think the formula rotl(vec2((rx/w),w)) could be simplified to vec2(w,rx/w), no need to rotate the vector. Also h/w is a constant so you could just write 1 instead unless you need the ratio of height to width for some reason, since your image is square this ratio happens to be 1.
Interesting, any chance for a tut where we could apply color grading for hihglights, midtones and shadows. I am especially interested to use this technique where you apply Lab for better mixing of colors
What I would really like to learn is how you learned about about to manipulate the procedural texture filter. I tried to reverse engineer the very poor affinity photo help pages some time ago. I suspect you have apriori knowledge that you are able to apple to affinity photo. I suspect you are skilled in computer graphics - so do you have websites to recommend to learn from ?
Thank you.. Most of it is basic logic, a lot of experimentation and searching on Affinity Forum (eg. forum.affinity.serif.com/index.php?/topic/112254-affinity-photo-procedural-texture-beginner-formula-info/ ). You could check the channel of @GraphicXtras.com www.youtube.com/@Graphicxtras1 . He has great videos about PTs PTs are commonly used in 3D and if you are really interested in PT, you probably have to search in the 3D world. The lack of documentation and scripting possibilities in Affinity makes it a very gray area to work on. Some interesting links. www.scratchapixel.com/lessons/3d-basic-rendering/introduction-to-shading/procedural-texturing.html math.hws.edu/graphicsbook/demos/c7/procedural-textures.html Hope this helps a bit :)
@@Graphicalfinity yes basic logic, but your knowledge of relative position is something I couldn’t figure out - yes I looked a while ago at some of those websites- this reminds me of 1977 when I read Unix operating system code to understand what was going on because documentation was so poor- one would think that if they spent time implementing the feature they would provide better documentation- unless somehow the math behind the filter is actually being used by the canned filters and the procedures texture filter gui might have simply been an internal test tool that they exposed ….

Thank you and agree with you.
Whaouuu ... Excelentisimo !! .. Bravo and thank you !
Many thanks!!
Thanks G-F ! Pretty unexpected effect you found in the Procedural filter !
You're welcome! Thank you too!
Thanks G, lots of creative possibilities. Where do the letters for the formulas come from and what do they represent?

Great. Thanks a lot.
Most welcome!

Does this Macro only import to Version 2? Not loading in V1.
You could be completely right... i recorded them in V2. You should be able to create them fairly easily (i provided the macros more for iPad users)
