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.

If at some point you read this .... could use a little help.

Progressing through but now stuck on page 11 section 4.4.

Cannot figure how to "drop or attach" the Mask On layer to the Edge Highlight layer.

Hi all,

I'm very happy to announce the release of Ultra Fractal 6.05. This free update for existing version 6 users improves anti-aliasing quality when rendering to disk (especially with higher Depth settings), along with various bug fixes and small improvements. You can download it here:

See here for a full list of changes in this version:

Hi ... from a newbie to UF and fractals .

Came across a tutorial by Velvet Glove on a marble sphere.
( thanks for all the articles Velvet Glove)

So I'm trying different things and have image below and could use some advice.

With each layer added, the layer below becomes less visible or a little duller.

My question is how would I correct this ... is this where a layer mask would

Hi All,
I'm trying to upload a new folder of fractal formula, as2.ufm, but how can i do it? Because on the author login the software allows only to replace as.txt or as.ufm etc....etc.. so i tried to upload as2.ufm keeping as.txt and i think that now i have upload a new .txt and not as2.ufm.
How can i do? Can someone one help me?
Thanks and good evening

I really need to start naming the layers so others might like to see new unknown techniques.

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

Greetings Folks,

This is my first post here and I would like to express my appreciation for this wonderful software. Frederik Slijkerman is clearly a world-class programmer and an all-around awesome guy and I value what he has created.

I've been fascinated with fractals since I discovered them in 1991 and wanted to incorporate some fractal zoom sequences into an animation that's synchroni

over the last years I have spent quite a bit of time thinking about how to render my fractals in the best possible way. I'm quite sensitive to image quality, at least I think so, since I'm often the only one to complain about it in the first place.

Just recently I found a great way for getting phenomenal results that doesn't include any costly software, it uses the completely free

I'm happy to announce the release of Ultra Fractal 6.04. This free update for existing version 6 users fixes several issues on Windows and Mac, especially when running on macOS 11 (Big Sur). You can download it here:

Just let me know if you experience any problems with the update.

Note: because these downloads are new, Windows 10 might flag them a

I’m new to this list but about 20 years ago I was a member of the UF Mailing List for a while together with my former wife Sharron. We had a fractal website called “Fracternity”, and maybe here’s the one or other fractal veteran remembering us vaguely. I have stopped making fractals for a long time, but now my interest is back, and in order to render one of my old

I’ve uploaded a new version of jlb.ucl with three new coloring formulas.

Decomposition2 is a generalization of Decomposition in dmj.ucl, by Damien Jones. It colors by the angles of #z, or of one of various functions of #z, at each iteration.

Statistics2 is a generalization of Statistics in lkm.ucl, by Kerry Mitchell. It colors by various statistics of #z, or of one of various funct

I’ve uploaded a new version of jlb.ulb with a new fractal plug-in formula, ThreeLevel. It’s a Barnsley-type formulas; these formulas define a critical value, and at each iteration some combination of z and c is compared to the critical value. If the combination is above the critical value, one formula is used; if below, another formula is used.

ThreeLevel uses two critical values
