I'm currently evaluating Ultra Fractal on a 30-day trial basis on my Macbook Pro laptop and have two questions before I purchase this software:

Once I've purchased the license for this software, are subsequent new versions of the software free or will I have to pay each time a new version comes out? If I have to pay each time the next version comes out, does anyone know how much that costs?

Ok, this might be a bit of a weird one, but I just managed to produce a problem that I've been meaning to reproduce for a while now:

Sometimes, when I and rendering something to disk while the preview is still also rendering, all UF windows start flickering erratically and the program becomes all but uncontrollable. In most cases I can somehow hunt down the window in question and close it or

I've been playing around with the animation feature lately and have been attempting some fairly simple Mandelbrot zooms at low magnification. I created an AVI file for a 15 second video (both 60fps and 30fps) at 3840x2160 resolution, but when I tried to load it up I get an error that the video file is unplayable due to possible corruption. I attempted to play the file under 4 different media play

Hi All,
I have uploaded a new version of SlopeMandNewton, this versione presents 10 sets, all compatible with the last one, now i can share also the parameters.

I was wondering, is there anything I regret about this fractal community that I've known for 20 years now?
Yes, there is something, I have lost several contacts due to different political views, I will start by saying that I don

I am writing a coloring algo at the moment and I tried using min(val1, val2) where val1 and val2 are two floating point values, and the function does not exist (error: invalid function). So I went looking for an equivalent function and I cannot find one. Does UF not have such a fucntion? It seems like such a basic thing. Am I just overlooking something?

When changing parameters, the image only updates after you change it again, after which the image will show the image with the previous parameters.

For example, starting with a power 2 Mandelbrot, changing the power to 5 will not update the preview, and changing it to 10 will update the preview to the power 5 Mandelbrot. Changing the power to 15 will update it to a power 10 Mandelbrot.

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

In the formula editor, if I open up a Replace Box with Ctrl-H and try to paste into one of the lines inside the box with Ctrl-V, the replacement text goes into the formula at the cursor position instead of into the Replace Box.

This is not the behavior that I had expected

I'm addicted with this new combination that i have discovered, here's another one, a different zoom of Newton Mask, i'm thinking to explore this formula and maybe create a new one exploring the Point of Source method in Slope 3D Enhanced III, it's the first time that i use this method in Slope and with Newton formula is perfect.
I will explore more
Ciao buon week-end

Request: Better control over periodicity checking.

Currently, periodicity checking is controlled by a limited set of options: "off, rough, normal, conservative". I don't know how it is implemented, but I am guessing some orbit distance threshold preset table or similarly.

I work with fractals that are very sensitive to the periodicity checking, yet turning it off altogether would real

Is it possible to display the colors of a gradient on a layer. just as they are displayed in the editor ?
Layer would be identical to gradient colors.

Brought in a wood texture image and applied kaleidoscope mapping.

Any way to remove white lines it creates ?

When I'm browsing formulas, it's very helpful that UF calculates and shows thumbnails of each possible formula.

There are also drop-down lists in many formulas, such as the built-in Function list (sin, sinh, asin, ...). It would be very helpful if UF could show calculate and show thumbnails of each choice.

Not easy to implement, but as long as I'm dreaming ...

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.)

The ResultIndex function of a GradientColoring formula returns a value for #index, an index into the gradient. The #index has useful values from 0 to 1. If #index is outside [0,1], 0 is used.

If Repeat Gradient is checked, positive values greater than one are reduced to [0,1]. For example, 3.7 becomes 0.7, which is in range. However, negative values of #index are still replaced by 0.

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.
