Why do I get this blurred distorted coloring? An inverse julia zoom:

MandelbrotJuliaZoomIncorrectColoring {
fractal:

layer:

mapping:
center=0.000993846291914812695705/0.000381483804274999567745

formula:

log(1.20515621346031e463) outputs INF in normal precision, NAN in extended precision (tried with up to 1e6 extra digits).

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:

int param n1
min=1
endparam
int param n2
min=1
max=@n1 ; compiler says invalid setting
endparam

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.

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.

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!

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

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

I've tried to reproduce the image posted here but failed, even at the "Precise" setting for Perturbation: essentially, the whole center is 'missing'. While such problems can always occur, I thought I'd report this in case you want to make the algorithm a bit more robust.

Hello,

I recently updated my CPU and got a Ryzen 9 3900X with 12 cores and 24 threads and that caused me to find what I think is a bug. To be clear, the program works fine, the image is rendered, so it's more of a nuisance than a real problem.

What happens, is that for images wider than 1931 pixels, certain thread counts will cause 50% of the image centered horizontally to be renderd firs

Hi, I got UF 5.4 on 5/17/2017. I upgraded to an UHD monitor 3840 x 2160 resolution about 6 months ago, and UF 5.4 is unusable because the interface does not support UHD, and the menus and fonts are too small and unreadable. Does the latest version of UF support UHD monitors?

I'm making some formulas that can nest and the parameter names get hard to see because the left part of the panel isn't wide enough. When I widen the panel, only the right part of the panel gets widened, not the left part, the part that I want widened. Here's the standard panel width:
and what happens after I widen the panel:


Could the two sides of the widened panel widen proport

I think it's a bug?
Why, when rendering, I write that I want for instance an 600 x 400 at 72 dpi and png, I obtain an image 600x400 but at 28 dpi?
I must resize with my favorite photopaint
What shall I have to do?
I see it is not the same with jpeg files where I obtain for the same parameters a 300 dpi picture?....
Thanks

I was wondering if there would be some way the user could control just how "smooth" smooth interpolation keyframes are, as in, how flat or narrow the peak is. The reason I am interested in this is because sometimes, even with smooth interpolation, the resulting animation ends up being too fast.

This may be through something analogous to keyframe handles in Adobe After Effects. Or perhaps an

UF reports the error "HTTP/1.1 301 Moved Permanently" and is unable to connect to the database. I assume that this is a result of server reconfiguration? Is there a way around this other than installing the update manually?
Thanks.

I've noticed something recently that has caused me some unwelcome extra work, although now that I've pinned it down I can take care to avoid it. I thought I would just mention the issue here in case it's something that needs attention.

The issue concerns the dragging of a Group to a new fractal window. It occurs in both UF5 and UF6 and can be 100% reproduced by doing the following:

Start

In one of my formulas there is a parameter that is required to be non-negative. If I put in a negative value, a sound plays and the parameter is not changed. Perhaps a message flashes on the bottom line of the window, but if it does, it's too fast to read.

This can be confusing to the user. A message like "Parameter out of bounds" would help if it stayed up a few seconds.

Pausing computation: Provided I'm not missing any existing functionality, is there anybody else who would welcome a pausing feature for 'normal' computations, i.e. outside "Render to Disk"? Sometimes when I was too greedy with open windows, I'd like to be able to prioritise which image actually gets completed first, or I keep a window open for some reason whose computation I'm not currently inter

Hi, I rarely use this merge method and I think it's not working the same in rendering as in display mode. This happens in the latest version of UF 5 and 6.

Thank to check out this. I'm losing some very nice parts of my composition.

Sometimes when rendering a single frame of an animation at high res, rendering stops near 90% loading 1 CPU and never finishes. If I delete the animation timeline it renders fine.
