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.

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:

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.

While watching a screen capture video of someone working in UF6, the Render window shows a resolution of 118.110 with no units. What’s up with that?
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.

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

and the formulas are incredibly simple

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.

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/
and see the pictures I've made here: https://mrvelocipede.tumblr.com/tagged/botob

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))
print("exp(i * #pi)=",m1)
float sin1=sin(#pi)
float cos1=cos(#pi)
print("cos(#pi)=",cos1, ", sin(#pi)=", sin1)

I found an interesting and visually pleasing phenomenon called Domain Coloring. Based on mathematical formulas, I don't know how closely it relates to fractals. I'm a big fan of rainbow coloring and when I stumbled upon these images I was mesmerized. Is there any way to make something like this in UF?

Perturbation-style formulas depend on the #dz value remaining small enough
for fixed-point arithmetic. I managed to sabotage myself by setting a high
bailout value of 1e20 on this deep zoom with perturbation.
After reducing the bailout to 1e10 the formula worked beautifully.
(I wanted a high bailout because I was using smooth coloring)

Something curious is happening. Here's an exported image from UF. Looks right.
Here's what I get when rendered (normal anti-aliasing, forced linear drawing).
Noticeable differences, not subtle. Not solved by changing anti-aliasing parameters or precision. And if I render the same thing again, different results!

Greetings,
I'm having difficulty while using the tutorial on animations. It seems that as I playback my initial animation, it zooms in horribly pixelized rather than a smooth image. Why is that?. I have been doing the tutorials up to this point and im stuck. CAn you give me a hand?

I'm confused about the public section are these designs subject to copyright or can they be used freely?
Hi, after using only notebooks for over a decade, I am thinking about getting a (Windows) desktop PC. Not being much of a gamer, my primary concern with performance is deep-zooming the Mandelbrot set in UF. Does anybody have a suggestion for this, or even a benchmark computed on their machine?
I've read Frederik suggesting an i7. Is UF specifically tailored to Intel? I never read anything abo

When rendering animations with motion blur, all is well for the first 90% of each frame. This is when UF is calculating the fractal and antialiasing. The four CPU cores are maxed out and the CPU is 0% idle, as shown below on Activity Monitor.
But then comes the final 10% of the frame, which is when motion blur is being calculated. UF suddenly gets a lot slower. The CPU is 70% idle.

Somehow, accidentally, I tagged an image as an animation, with one parameter having the animation indicator. As far as I know, I didn't do anything to do it, certainly not on purpose, and Animation was turned off as far as I know.

(2) How should I undo it? I didn't see any way, so I edited the upr, taking out the code for

I've created serveral animations where I create with outputing slides to png's.
Though I noticed sometimes if I make a zoom animation too fast... the slides look blurry. Are there any tips anyone can give as what is a good "time frame" so the zoom is not too fast ratio to time so it wont look blurry?
I hope that makes sense.
I can upload a few frames if it helps.
Thanks in adva
