Hi All,

There were six fractals last month.

You can find them and the older collections at the cloud of Microsoft:

Example 2 also uses Power as the Initial Formula, but Two Formulas as the Main Formula. Formula #1 is a J-type Lambda, and Formula #2 is an M-type Lambda. Bailout is Divergence. Different bailout types give different results.

My default upr uses SwitchComboFormula in jlb.ufm plus JLB_SwitchFormula, JLB_SwitchCombo, and JLB_MandelbrotSFormula in jlb.ulb. I had a typo in the Mandelbrot,
default = 1"
in a parameter block. When starting up UF, I got a large number of confusing and not helpful error messages, as in the screen shot below.

When the (blank) fractal loaded, I clicked on the top line, SwitchCombo

I've been a longtime user of Photoshop and other graphics applications, but not spent much time creating fractals. I've looked at hundreds of fractals and there is one style in particular I really like and would be happy to create in a variety of ways. I think it's referred to as chaotic bundle or chaotic thread, but I may be mistaken regarding this. What I need help with is the steps in UF to cr

This .upr runs in a few seconds at 640X360.
On 6.02 it takes about 3 hours at 19200X10800 (no AA).
On 4.03 it takes about 10 mins at 19200X10800 (no AA).

Hello!

I have been lurking here for quite a while, with only the occasional post, but over the years I have spent lots of hours in UF, and I enjoy it a lot. What got me into UF originally, was the fact that I can write my own formulas, which I have repeatedly done.

Just last week I tried a way of combining the Mandelbrot Set (nice shapes, but nothing new at this point) and the Burning Shi

Hello,

This might be a dumb question, but I wasn't able to figure out where I can share parameters or formulas or other stuff, such that they make it into the public collections. Where do I upload or send them?

Best regards,

A favorite coloring of mine in XaoS Fractal Zoomer is one called Biomorph. It changes shape depending on the bailout used. A low bailout such as 8 gives a stubby wider shape and a high bailout results in a more pointed, spike shape. See the pics here. Is there anything similar to this in Ultra Fractal? Jam2.ucl has biomorph and Outside Options under Fractint (Compatibility folder) also has bi

I've wanted to be able to add a vignette (a darkening of the corners and edges) to a fractal as is common in photo editing software, so finally I wrote one. It's Vignette in jlb.ucl.

It's a direct coloring, producing a layer with white at the center and grays to black at the edges. It is meant to be used as a top layer, with Multiply. Here are the parameters:

I've added a revised version of QuadMirror to jlb.ulb. QuadMirror2 is a transform that takes a rectangular block from a fractal layer and tiles the fractal evenly with the block, mirroring it both horizontally and vertically.

The user specifies the number of blocks in each direction, the center of the original block, and where the original block goes (unmirrored). Because of the mirroring, t

Rendering animations to png image sequence usually has several unfinished images. This also happens often when just editing a fractal. Refreshing zoom then gets rid of it.
Typical example included.

I've been having problems with what I believe are artifacts. They seem to have some connection with function settings, particularly exp, and cotan, cotanh, tan, tanh, cos, cosh, sin, sinh.

Here's an example from om.ulb, featuring a transform which maps according to various combinations of functions:

I am currently on working on creating some fractals and animating them.

I had a question... I tried doing a fractal animation and it takes about 3-4 days to render and then at the end the log says "Error Saving image (error)

Is there another log where I can figure out what the exact error was?

According to the log it took close to 60 hours to finish so I do not want to go through it

Does Ultra Fractal offer any of the lambda fractal planes, as described in this link? I am aware of the inverse fractal mapping but was wondering if any of these others are possible as well?

I stumbled upon an amazing combination of variables: the standard Pixel formula with Gradient for family Outside coloring (sam.ucl) and the Inverse fractal plane mapping. How does such a transformation take place from a bunch of squares formed by the gradient to a beautiful rounded geometric pattern? I am baffled and pleasantly surprised!
