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
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!
These are done with all 12 of my CPU's cores (6 real co
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?

Hi All,
This previous month one new fractal parameter file in the collection.
You can find the whole existing collection at the cloud of Microsoft:

I'm confused about the public section are these designs subject to copyright or can they be used freely?

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.
(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

Is there a way to create an animation that just color cycles the fractals?
I'm contemplating writing a new mapping formula. I could write this as a transformation in a uxf file, or use Plug-In Transformation from Standard.ulb and write a UserTransformation to go in my ulb file.
So far, I don't see any advantages to doing it one way or the other. Comments?
In a float param block, the compiler allows
default = 1/#magn
which can be useful, but doesn't allow
min = 1/#magn
which also can be useful.
Also the help entry "min setting" has a typo. The sentence "If this setting is not specified, there is no maximum value for the parameter." Obviously it should say minimum.

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
I have a problem. I tried using perturbation theory for the Magnet Mandelbrot type I fractal, but after going a quadrillion zooms, the image becomes... well, you know what happens.
The code:

; Magnetic Mandelbrot set type 1. Use Switch Mode to select a

;
init:
z = @start
c = #pixel
x = real(z)
y = imag(z)
i = sqrt(-1)
loop:
z =
Would someone have an example of a neg mandel param similar to those of Dan Wills? I have only just come across these and woud like to play with them.
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
Has anyone tried to make a fractal from the Jenkins-Traub algorithm?
https://en.wikipedia.org/wiki/Jenkins%E2%80%93Traub_algorithm
Here's a fractal with 100% of points Inside; no points reach the bailout criterion. The Statistics tab says that the Min and Max iterations are both zero. I would have expected that both Min and Max would be set to #maxiter.
This is either a bug or a feature.
Here's an example:

Currently #numiter is readable only in the Final section of a ucl coloring formula. It is not even readable in the ResultIndex function of a ulb Coloring formula, where one might expect to be able to use it.
If #numiter were readable in any coloring formula, whether in a .ucl or. ulb file, some interesting coloring options would be available. For example, if coloring according to distance fro

Hi, this is my first topic here and I want to know how do I make matrices in Ultra Fractal.
Thanks!
Hey guys, Fate here! I just realised that in the 15 years I've been using UltraFractal, I've never actually made a post here, so I wanted to start out with a bang!
I'll be sharing the parameter packs that I've assembled from my pieces and share it with you guys here, on the off chance you don't have a deviantART account!

The compiler objects to the continuation character in the example below, says it's not a valid character there. The truth is that the comment is not allowed there (should it be allowed there?), and the error message is wrong.

It's fine without the comment.
