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,
Phillip

Hi All,
There was one fractal last month.

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:
radius: inside this radius, t

In the default section of a formula, I would like to be able to do the commented line below but the compiler does not allow it:

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
Why do some fractal formula give a light blue field for their preview? Gnarls in tma2 and mt for examples.

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.
In UF 5 and UF 6 I can not open the formules Image Traps and Image Tiler. Both formules never worked. What to do?

Just purchased Ultra Fractal 6 Extended Edition and loaded up the animation example. Clicked run and in a few seconds it crashed. Not off to a good start.

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
Since years I receive the same mail, with the title "warning".I don't know how to stop this .

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!

Any idea what's causing the black to appear over the fractal image? I suppose one of the variables is out of range but I happen to like the design I'm seeing on screen and don't wish to vary it too much. Thanks!

The Absolute Julia transformation is made by taking a fractal and mapping each coordinate to its square root.

I usually render to disk with a resolution far higher than that of the fractal window. Sometimes, this means that perturbation mode would probably be used for the rendering, but I have no way of setting the precision level because it's only shown when that mode is also used for the fractal window.
Hence, I'd either suggest such an option in the rendering dialog, or to make the perturbation pr
I have a formula and want to add a new parameter to it without breaking past fractals. The formula has a version number in it, such as this declaration in the default section:
int param v_SFormula
caption = "Version (SFormula)"
default = 100
visible = @v_SFormula < 100
endparam
If the new version of the formula has "default = 101", how do I put in the ne

Doing an animation of a zoom. Occasionally I get a bad frame, like this one. What happened? Details available upon request.
