Can someone verify if they can find noise input presets in the bottom preset area above the controllers? If so, there are a few my examples for your pleasure...if not I will post some images...

I may have simplified it from a preset as it indicates octives and persistence. It is an easy introduction into something different and in it's black form I had no perceived use until now in r,g,b. Please note this can be expanded upon introducing a scale factor to grow, variables for r,g,b separations, etc.. By complete coincidence, go to Graphicxtra.com on youtube and see today's Affinity Photo video. It will help you finish this off to new levels of creativity!

While this may be better explained by a math professor or an Affinity developer, I will try to do my best to dissect these into digestible bite sized portions. Soon I plan on posting some basics on rx,ry math. May be easier to understand in a video(not my thing...yet...) due to having a visual reference. I will include simple macros of movement examples. I think that seeing it and being able to play with it at the same time helps reinforce the connection. Right now I am about 8 macros ahead of myself of R,G,B variations of the standard presets. It has increased my appreciation for these formulas beyond belief. They are all usable by the beginner to create multi colored gradients or use as a starting point and just have exponential fun. Looking forward to your and everyone's contribution to this. - T V

Sounds good, not sure how to do that yet...this started off as a call for help rather than a tutorial. I am just using this as my online reference with examples that got organized maybe enough for others to follow along. Things are moving so fast that I am needing much organizing as I closed AP last night with a great PT using the squares still open not saved and in starting over turned out different. Not quite as nice. One day maybe we will all get a little more confidence working with it. Glad your enjoying it!

Hello All, I have been inspired by a thread I started this morning on Basic Procedural Texture Deconstruction to allow beginners to see into the process and the math to be able to create their own Procedural Texture. I thought sharing some of my documentation would be a good place to start and fortunately videos are available at Graphicxtra.com. They are a great resource. Unfortunately, not how I got started, but, I am so happy to have found them that I will start seeing if I can work through an entire video at some point. For now, I am still figuring out that gradient macro workaround and this is a linear variation that introduces another formula in a unique way. I hope you like it as I hope to expand on this one a little. LINEAR V2.0 Formula: smoothosc((c1*rx-d1*ry)*a1/w,b1) smoothosc((c2*rx-d2*ry)*a2/w,b2) smoothosc((c3*rx-d3*ry)*a3/w,b3) Inputs: a1(R),a2(R),a3(R) lines b1(0,1),b2(0,1),b3(0,1) hard edge c1(-1,1),c2(-1,1),c3(-1,1) horiz shift left, right from center d1(-1,1),d2(-1,1),d3(-1,1) vert shift up, down from center For now, this produces linear gradients that shift left or right, up or down, rotate limited( this happens when using the horiz shift and the vertical shift at the same time). The R,G,B creates multi colored gradients. This layer is non destructible and applies at 50 percent grey coverage at 100 percent opacity for choosing color gradient. Set blend mode to overlay or soft light to see image and adjust transparency to taste. T V - LINEAR PT R,G,B V2.0.afmacros Enjoy and Experiment - T V NOTE - I started a new beginners supplement to the Procedural Texture Help section in the tutorial resource section. You will be able to find more examples with free Macros and my attempts to break them down in understandable ways. It should help others become a little more comfortable with this incredible process. Future examples will show up on the tutorial forum page...

Please note that I can apply a radial gradient from a macro under these conditions. With a radial gradient loaded into swatches, apply gradient using rectangle tool. The unfortunate part is that the center of the radial gradient is relative to the (0,0) coordinates effectively quartering the gradient. Linear gradient works fine. If I am recalling correctly, the linear gradient only loaded a single color and not the gradient in previous versions. - T V

Hi Everyone, I have been on a mission to fill the void in the Macro environment by the lack of gradient support. To this end I was introduced to Procedural Texture and saw some possibilities and started tinkering. The manifestation of this can be found in several working groupings of R,G,B Vignettes and Linear gradient macros uploaded in the Resource section that I will update as interesting developments occur. In this, I will attempt to break down some of the math and show you how I am attempting to work around my limited knowledge of geometry(has been a while since trig) to make this accessible to the beginner who wants to implement some control over the basic examples and give some direction over how to navigate this powerful tool. If you would like some immediate video immersion of outstanding examples, that I may start from or point to, see Graphicxtras.com on youtube. If anyone has anything to add/correct/questions, comments, etc. please jump in...this is only meant as a supplement to the Affinity Photo Procedural Texture help section that can leave the beginner a little overwhelmed. So, here is the first installment of my experiences. And certainly, if anyone wants to use these explanations in video format please feel free...just post a link for everyone to see it. Procedural Texture 101 https://en.wikipedia.org/wiki/Procedural_texture These are some common definitions of elements of an equation w = width of document h = height of document x = horizontal axis y = vertical axis rx = relative x(position) to upper left hand corner expressed as (0,0) horizontal axis (rx,0) ry = relative y(position) to upper left hand corner expressed as (0,0) vertical axis (0,ry) R = red channel G = green channel B = blue channel A = alpha channel Relative x and y (rx,ry) x and y coordinates can also be specified as values relative to any starting point on the screen or any subset of the screen such as an image. On the Web, each clickable area of an image map is specified as a pair of x and y coordinates relative to the upper left-hand corner of the image. https://en.wikipedia.org/wiki/Cartesian_coordinate_system osc(input, parameter) The following syntax follows the typical convention of function(input, parameter) where the function( = osc ) https://en.wikipedia.org/wiki/Wave_function https://en.wikipedia.org/wiki/Wave_equation https://en.wikipedia.org/wiki/Oscillation_(mathematics) osci(input, parameter) This function example represents the oscillation over the set (in this case an interval) of the function( = osci ) https://en.wikipedia.org/wiki/Interval_(mathematics) This example is formula from the Checkered preset osci(rx*c/w,ry*c/w) variable c(Z) produces squares + addition of variable a(Z) to control vertical axis osci(rx*c/w,ry*a/w) c(Z) produces horizontal rows a(Z) produces vertical rows example. c=0 (no horizontal rows) c=1 (1 horizontal row) c=25 (25 horizontal rows) c=5, a=5 (square with the size of 5 rows horiz and 5 rows vert)(effectively enlarging 5x larger than (1x1) c=5, a=1 (rectangle with the size of 5 rows horiz and 1 row vert) etc. See video example of procedural texture squares at Graphicxtras.com I will update with macros of these examples as I go along, or if you want to get started go to procedural texture and find the checkered preset and start experimenting. orig softlight 50 checkered R,G,B enhanced* * enhanced with Dave's Shifter Macros(slight tweeks with all 3) looks like candy.

With a little help from my friends, I offer a fresh look at linear gradient procedural texture formula. Yes, it happened in a flash this morning, so, examples will have to follow. This is complete with some exceptions that I was experimenting with a little last night... V1.0 Creates very controllable R,G,B linear gradient with edge hardness, contrast, tint, tone, etc. V1.0 needs wants desires 1) Point of gradient spread. (It should be represented as a fraction from location point rx, ry -/+.) 2) Scale controls.(push left/right/up/down) 3) Skew controls.(angular push) 4) Rotate controls.(being able to use angle input or elevation/rotation controls would be great, my current rotation is very limited 45...yes, I know) grad 100 grad edge 25 grad edge 50 grad edge 75 grad edge 100 contrast 2 contrast 5 contrast 8 lines 2 lines 3 lines 4 lines 5 lines 5 edge 50 lines 5 edge 100 blue 100 blue 100 redt 50 blue 100 redt 100 redt 100 redt 100 edge 100 * It is important to note that red, green, blue (0,1) controls base or areas of gradient with no color, redt, greent, bluet controls gradient color. The gradient is expressed at a rate of 150 percent coverage of width. It could be removed or controlled by a variable. This macro is 100 percent non destructible and does not use the R,G,B image information in its calculations. Use transparency and blend modes to taste or add a white pixel layer under procedural texture layer, merge visible, and use that layer as a gradient. I am currently at a loss as where to insert the formulas for scale, skew, rotation without completely altering this in undesirable(controllable) ways...also, is it possible to batch process pixel layers? Macro will not export...

Offset rx, ry variables might be interesting for greater variation... >>Originally set for horizontal image. Running this just now on a vertical image the gradient just needed to be shifted over.

Creates different color combinations. Change R, G, B channel formula rx to ry. Creates horizontal and vertical channel combinations. Rotation and offset would enhance angle of color. Rings or other shapes would be interesting. Combining using differing formulas on differing channels((R)rings, (G)linesH, (B)linesV),etc.. Question...How much is too much? Simplicity is probably the route to go when these get cleaned up(more digestible). One set of controls and have plug in effects... Examples to follow...

For your pleasure...I have been busy working this vignette thing again, and I think, this is getting somewhere. Completely different approach to achieve a more controllable experience in every way to the gradient macro workaround, and well, much, much, more. First, this macro/procedural texture is set up for a round gradient. Like the original, it applies perfectly to vertical and square images. To center the gradient on a horizontal image(should not be off by much), double click the procedural texture layer and use the crosshair over image to drag and reposition. The controls will allow the complete control over shape(horiz, vertical), size, gradient, etc. If you want an old fashioned mask layer, set blend mode to normal and opacity to 100 percent, merge visible, turn off procedural texture layer, invert merged layer, reset new blend mode to multiply, set new opacity to taste. Of course, that is just for the black gradient vignette...the possibilities are in the experimenting... Red, green, blue (0,1) controls the entire image the same as normal R,G,B sliders to mix color. Red, green, blue (-1,1) controls radiate from the gradient center. Layer opacity 50% blend mode subtract. (R255,G0,B0) (R0,G255,B0) (R0,G0,B255) (R,G,B=255) (R,G,B=0) size 5 red 100,0,0 redt shift more redt shift intensity 2 ring 3 shift +redt shift +grnt shift 25% trans 50% soft light 50% vivid light 50% soft light T V - VIGNETTE PT R,G,B V2.afmacros T V - VIGNETTE PT R,G,B V2.1.afmacros T V - VIGNETTE PT R,G,B V2.2.afmacros T V - VIGNETTE PT R,G,B V2.3.afmacros *** V2.1 Adds three (R) ring progression controls (over the 10/10/10 fixed spacing to g(R)/h(R)/I(R)) (these could be enhanced in two ways; adding a scale factor control to each of these (R), and or add controls gr(0,1)/gg(0,1)/gb(0,1), etc. to create some enhanced color variations. *****V2.2 Reorganizes, relabels, restructures formula.

Macro setup for center horizontal photo, slightly offset in vertical. *******V2.3 Corrects black gradient with invert. ++> future needs for this is a control to rotate. - Ultimately, a way to control color choice, order, midpoint, etc.... V3.0 New formula, more with less...radial, linear, R,G,B offsets, etc. While getting this together this AM, practicing the new fad of social distancing, TV on, and a nugget pops up with Joan Jett +3 in different locations, jamming a song called 'New Light of Day'. Starts off kinda slow and wonky...gets going and wow, grooving on an inner plane, I am feeling energized. Nice start to the day, so, here you go, another round of jamming...

Please feel free to comment, as this will also help others expand their comfort zone! A mind is a terrible thing to taste...😉 If you want more... go see Graphicxtras.com on YouTube! I am on a new formula, starting from Linear gradients, that is looking promising as an upgrade. I have some shifts/skews to add, and we will just have to see... Hope someone out there finds this entertaining at least. When I am moving the dials one click at time, the new possibilities just keep going...why this gradient thing? Never thought I would still be diving deeper into this, but, here I am...MORE PROCEDURAL TEXTURE PLEASE! Yes I am going to have to make a macro to generate examples for posting...

Today, I was on a search for Procedural Texture formulas and I found one in the help menu, thanks Affinity! Instead of giving you a macro based on that alone, I added (0,1) controls for red, green, blue. This expands the versatility of the radial vignette to create color toning, blends, etc., as well, all in one. The controls are set up for a black round gradient vignette. When applied, the gradient is sized and centered to the image and will add a non-destructive layer above the layer stack. This can be applied from any selected layer or not. Double click on the Procedural Texture layer to open the Procedural Texture dialog box. With the Procedural Texture box open, select any point on the image area to move the center of gradation. The first (3) controls change the size and depth of gradient. The second (3) R,G,B(0,1) controls offset the black gradient to color, just as normal R,G,B control sliders. +++ After further testing, the settings of the macro set this up perfectly on square and vertical images. For horizontal images try changing the 1st control to 25%, 2nd control to 50%, and 3rd to 2. Experiment and Enjoy! - T V My hope is to learn how to replicate this in a linear fashion, amongst others, which, will fill a current need in the macro environment to be able to produce a variety of color gradients options. ***Any help will be rewarded with more macros ✌️ ...I just finished another (divided) version which produced interesting results...also, another gradient vignette version controlling EVERYTHING completely differently...
