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

Completely new to Ultrafractal.

Is it possible (and if so, in a simple way) to do black and white (no gradient) scatter plots for Julia sets with Mandelbrot parameters (i.e. constant offset) as input (ideally selecting from a Mandelbrot plot)?

And is it possible to adjust "dot size" for that in a reasonable way? Background: The goal is to have these printed, and pure dots on big resolutio

I have an older INtel i7 computer I don't use anymore because I replaced it with newer one. I would like to use the old I7 computer as a server. To my understanding. THere is a way to make the older computer into a Server. Reading the instructions I am trying to understand some things.

Does having the server mean that all computation runs on the server all computers running server or is

Brought in a wood texture image and applied kaleidoscope mapping.

Any way to remove white lines it creates ?

Hi Frederik,

When using UF6 (and the previous versions also) my computers CPU (Intel I5 with 4 cores) is working at 100 % while my GPU (NVIDIA GeForce GTX670) is doing ... right ... nothing at all.

There are softwares - I'm refering to "SETI@home" (*) - that are doing math calculations and are using not only the CPU's in your PC but also the GPU as you can see on the diagram below and th

I saw a painting by Bridget Riley (see and wondered what I could make that would be similar. It’s clearly a case of adding waves to horizontal lines.

I wanted to start with a pixel formula and a coloring formula that would just reproduce the gradient horizontally and then apply a

The Waves transform can be used to generate interesting patterns or textures. The left third of the strip is the image from Group 1 of the upr below; it is the difference of two layers. The middle third is from Group 2, which is the difference of three layers. The right third is the difference of the two Groups. (I made the strip from three separate images using the FastStone Image Viewer.)

Many of you may have noticed that it was impossible to log in to the forum during the past week due to issues at the hosting provider responsible for hosting the Ultra Fractal web site. I'm very pleased to say that this has been resolved and the forum is back up again! My apologies for the outage.

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

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:

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:

After reading Crystal Wizard's post of February 4 (, 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.
