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.

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 :
As you can see I have a resolution problem on this last sketch due to the very high magnification (about 256 t

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

Dear UltraFractal folks,

I’m writing in the hopes that someone might assist me. I’m new to Ultra Fractal and am trying to replicate a very specific look for an art project I am developing. The closest example that I can find is one posted by Robert Töreki here: https://www.ultrafractal.com/showcase/robert.html
In his caption he mentions that it is “A study of using t

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?
Here's a link: https://www.dynamicmath.xyz/domain-coloring/dcgallery.html

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

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.
(1) How could I have done it, and how could I avoid it in the future?
(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

Hi folks. I’ve made a zoom animation. I like it and now I want to extend it by adding another section at the end. I want the zoom speed to stay the same for the whole animation. In other words, I don’t want the movie to zoom in slowly during the first part and then zoom in quickly during the second part.

I’ve found the image I want to use for the new end frame. But UF w

Mark Townsend's Fractalia formulas in mt.ufm in essence is

xnew = quadratic in x and y
ynew = quadratic in x and y
znew = xnew + flip(ynew)
Since each quadratic has 6 free parameters, he made 6 versions, Fractalia-1 through Fractalia-6, so the user could switch among them to help find good parameters.

My version instead uses one or two steps of randomization of parameters to help find a g

I messed up my panels somehow.

At one time I could have both panels open at the same time and docked on the right side.

Now I can only have one open at a time .... if I click one, the other closes.

Any ideas how to fix them.
