I recently noticed that the ampersand character & seems to be ignored in the caption of a parameter, although it shows up properly in the caption or text of a heading.
Try something like
heading
caption = "this & that"
endheading
float param p
caption = "this & that"
endparam
When the formula is invoked, the & shows up in the heading, but no
I'm moving to a new computer. I've installed UF6.05 successfully. Where on my old computer are my Preferences saved? I'd like to just copy them over to the new computer, with a little editing.
The usual place would be
C:\MyName\Appdata\Roaming\Ultra Fractal 6
but I don't see anything useful there.

I'm trying to create a Droste effect animation of a single image inspired by M.C. Escher's print gallery version from a Leiden University study. Here is a sketch I made :
Thanks to Ultra Fractal and a Droste plugin from Jos Leys, I managed to create the desired effect :

I've been a longtime user of Photoshop and other graphics applications, but not spent much time creating fractals. I've looked at hundreds of fractals and there is one style in particular I really like and would be happy to create in a variety of ways. I think it's referred to as chaotic bundle or chaotic thread, but I may be mistaken regarding this. What I need help with is the steps in UF to cr

Hello,
Would someone be kind enough to take a look inside the sp3 formula folder. All I'm seeing is a bunch of gobbledygook and the formula I'm looking for is called Cubic Parameterspace 3. I'm trying to upload a parameter set of Ingvar's on DA and it's not working. I have updated all my formulas.
Here is what I see inside that folder:

Hello,
I have been working with a formula for a while, which I have been calling Mandalamandelbrot and Mandaljulia, because it creates nice patters with circular symmetries depending on the location and parameters used. Here are a few examples:

I've tried both with the client on my TR Pro and the server on the 10/20 core i7-6950x and the other way around; regardless of which direction it's going, only one core on the machine set up as the server is used. (tested that just in case it was deciding offload wasn't worthwhile). I checked affinity and it was set to all cores for the server process and the client was set to 20 cores on the
Do you think we should add a dark theme for Ultra Fractal's GUI? It would be less straining for our eyes. Thanks
When writing formulas, I frequently make errors that the compiler finds. The compiler then moves the insertion mark to the location of the first error that it finds. The insertion mark is somewhere on the current page, but it's not easy to see.
I'd like an option in Preferences to make the insertion mark more visible. Perhaps larger, or a different shape, or a different color.
A tiny thing, but...
In writing programs, what I really miss from my days writing in C, is ++, being able to write n++ instead of n = n + 1. Even better if it's BigArray[LongIndex]++.
The built-in functions include round, floor, ceil, and trunc. Trunc rounds towards zero. For floats, the behavior of trunc is equivalent to the following:
float func trunc(float x)
if x >= 0
return floor(x)
else
return ceil(x)
endif
endfunc
There is no equivalent function with < instead of >. In mathematics, I haven't even found a name for this. The best name that I cou

I was hoping that switching the center parameter's keys to smooth interpolation would result in a smooth change of direction in a zoom animation. A gentle, natural-looking curve instead of an abrupt turn-on-a-dime. But the interpolation settings don’t seem to have any effect. It's always the same sharp turn halfway through.
Smooth interpolation:

I am rendering some simple fractals, but it seems to take more time than it should. I find that the 4 Efficiency cores are running 100%, while the other 4 Performance cores are all idle. Interestingly, this doesn't happen when I am previewing the fractal. The rendering speed would be greatly increased if this can be fixed.
By the way, I am using a MacBook Air with an M1 chip.

Hello,
I was just playing with a fractal and noticed that there should be a very nice way of coloring my fractal if I juuuuust got the gradient offset and color density right. But I need to adjust them one by one, going back and forth. I think for these two it would make sense to have a 2D explorer - like we do for complex variables - where we can adjust color density on the x-axis and gradi
This month I've been using Ultra Fractal to make illustrations based on drawing prompts generated by an AI. Kind of a frivolous exercise, but it has definitely sharpened up my techniques for using coloring formulas.
You can read about the prompts here: https://www.aiweirdness.com/botober-2022-draw-human-draw/

I see the only version of Ultra Fractal available for macOS is still an Intel build. Are there plans to do a build for the new Apple M1 processors? I imagine it would be a lot faster for those devices.
This is allowed in the default section of a ucl coloring formula, but not in a GradientColoring plug-in.
Apparently I have to make my own version of GenericGradientColoring from standard.ucl and put "render = false" in there.

Chaotic Attractors Tutorial
These, often called Strange Attractors, are iterative systems that don’t seem to go anywhere, but do (approximately) repeat. Unlike most of the formulas in UltraFractal (UF), the iterations don’t diverge to infinity or converge to a point.
A simple example is the Clifford Attractor, named after Clifford Pickover, as in Layer #1 of the upr file at th

After reading Crystal Wizard's post of February 4 (https://www.ultrafractal.com/forum/index.php?u=/topic/832/dr-pickover-s-suggestion), I got inspired, or perhaps carried away.
In the Tutorials and Tips section of the forum, I have put a tutorial on my new Chaotic Attractors coloring formula and a upr with 15 sample layers. As a teaser, renderings of two of the layers are below.

I follow Pickover on twitter, and he made this suggestion today
"A simple formula produces strange and unpredictable forms — wispy, chaotic ghosts composed of 10 million points. "
here's the link he provided

HEIFs are about 1/3rd the file size of PNGs, which are the smallest lossless files Ultra Fractal can write.
I’m converting the PNGs to HEIFs with another app but it doesn’t batch-process very well. It’d be sweet to have lossless HEIF right from UF. Even better if the files are saved with the .heif extension not .heic because Final Cut Pro and other apps don’t recogni

I added a hard drive to my computer ( D: )
and moved UF to that drive.
Tried copying over parameter files to D: drive and adjusting Pref locations, when I got the error message.
Apparently parameter or public paremeters cannot be relocated.
Tried to set back as was, but still get error message.
Any help advice appreciated.
Starting a day or two ago, the names of the files that I render from UF6 have -00019 added. That is, instead of xxx.jpg, the file is named xxx-00019.jpg.
What could be causing that? I've restarted my PC, same result.
In arbitrary-precision arithmetics, the sign of the result of trigonometric and exponential functions is sometimes wrong.
Here's an excerpt of a formula printing some debug results:
complex m1 = exp(flip(#pi))

float sin1=sin(#pi)
float cos1=cos(#pi)

When I run this without additional precision, I get the following res
