When loading an old fractal after changing my formulas (without proper attention to old fractals), I got this error message:


In fact, the missing parameter is not in SwitchComboFormula in jlb.ufm. SwitchComboFormula calls SwitchCombo in jlb.ulb, which calls Mandelbrot in jlb.ulb, which has the missing parameter.

If the error message could be improved, that would save some debugging

Hi All, I'm Andrea Spinozzi from Italy, thanks to Frederik to add me at the forum, i'm doing fractals from 2002 and the passion is never stopped I share with you some parameters creating with a formula that i will upload next weeks in the UFDB, the folder is named as2.ufm at for the moment you can download on my site and name as2.ufm in your directory of UF, the folder has 11 hyper complex formu

This fractal is for the April 2022 Challenge at https://www.deviantart.com/ultra-fractal-redux, which required using formula “Gnarlathotep 3 reversed version 2” in ejb.ufm. It surprised me that a Color Density of 0.0001 was needed, a new record for me. You'll need to update your formulas, as I added an Over/Under coloring and a Mask Coloring to jlb.ulb.

Hi All,

This month 3 very beautiful fractals in the collection. As you can see in de upr file, there is a fourth fractal in the upr but I was unable to create it.

That seemed to work, as you see I am logged in now. Many moons have passed since my old fractal days. Back into it, and thoroughly enjoying fashioning fractals again. Also hello everyone new member to this, but old member to the mailing list.

I am basically lazy when it comes to building fractals with a lot of layers, I have grown use to not getting confused and knowing where I am. This is quite a large set and takes a time to load depending of course on your RAM. Have a tweak if you wish?

The previous "Sixteen Ways" kept the formula fixed and changed the coloring on the Outside tab. This version is the opposite, using the new "tweaking" capabilities in the newly uploaded jlb.ulb.
The coloring uses the Arithmetic Average of the distance of z from the origin, starting with iteration 8 and continuing for 100 iterations, or until bail out. All 16 mini-fractals use the same colorin

Hello,

since some people were wondering how I made some of my images, I decided to write a short tutorial on how to use the coupling loops formula in phs.ufm which I used several times over the last months.

When you first open it, this is what it looks like. The loopy stuff is located in the valleys of the main set and also the minibrots. As a rule of thumb, the higher c is, the stronger

Hello,

I upgraded to UF 6.04 today and every time I open the explorer window for any parameter I get a huge CPU spike. This happens even if my mouse is nowhere near the window and nothing else is rendering. This takes several seconds and despite having a 12C/24T CPU it drains my computer of resources to an extent that even the playback of windowed Youtube Videos starts to stutter.

Hello!

I'm currently rendering a fractal that told me it would take 8 hours initially, quickly rose to 9 hours, then 10 hours. Now it has been running for almost 3 hours and it still predicts between 9 and 10 hours.

Here's my guess of what is happening: The fractal is basically a spiral with the highest iteration counts toward the center of the image, so I would expect the rendering to sl

Hello,

I recently ran into the problem of wanting to use the switch to Julia mode on a pretty multi-layer fractal. It would be great to have a way of using all layers for the new Julia fractal, rather than just the active layer. I get that it's possible to do them one by one and copy-paste them into the same window, it just seems a lot more tedious that it has to be.

Best regards,

This image has 16 fractals arranged in a 4 by 4 array. All 16 have the same gradient and the same Formula tab (Julia from Standard.ufm). All of the Outside tabs use Plug-in Coloring (Gradient) from Standard.ucl, and the Distance Coloring plug-in from jlb.ulb. The di

Here's a fractal using some of my recent formula classes. The iteration formula class is Threelevel, and the coloring is DistanceColoring. ThreeLevel is inspired by several formulas with Barnsley in the name, where one formula is used if some function of z is above a critical value, and another if below.

Feel free to tweak.
