I am absolutely brand new with this software and am finding the tutorials frustrating in that the images do not seem to coordinate with the views I see in the toolbox section at the right of the screen. The tutorial images seem to be outdated and therefore I can't learn the objective at hand.

I'd like to start with simply modifying a formula. Any help is much appreciated.

I was a user of coreldraw (with photopaint) X4 and moved to corel X6.
I could import very correctly tif from ultrafractal to corelphotopaint x4.
Now, it is impossible for me to import UF tif files to corel photopaint X6.
I can only import png files into Corel PP x6.
I think it's a bug from Corel and found no response in their forums .
I tried exporting with the various options in U

Plug-in Tutorial: Image Traps Part III

This is the last part to the tutorial. All of the example uprs use plug-ins for the Colors slot. Two of them are slow in rendering as they use an emboss convolution filter (3 min 31 sec for EtchedMetal and 16 min 22 sec for EmbossedGnarly on my computer - Intel quadcore 3240 3.4 GHz). Be sure you have Ultrafractal set so that the minimum number of threa

In writing this tutorial some bugs were found in some of the plug-ins. Please download a new copy of reb.ulb before continuing.

Continuing with a survey of the main plug-in slots the next section is Images and Coloring. The primary slot is Colors with a default plug-in of No Color. The base class is ColorTrap, which is in common.ulb. The following plug-ins will plug into the Colors slot, but

This formula is derived from the Ducks formula in sam.ufm with multiple modifications. Bailout is determined by the number of iterations rather than a convergence or divergence criteria, so an iterations parameter which is independent of the value on the Maximum Iterations value on the Formula Tab has been included. The value for 'Iterations for Bailout' must always be less than the Maximum Itera

'Widgeon', a variant of 'Ducky Plus'.

'Widgeon' is based on the same principle as 'Ducky Plus': change of the kind of operation during the iteration process. In 'Ducky Plus' there are 3 steps, each with a number of iterations, here in 'Widgeon', the second step consists of only one iteration.
So for each treated pixel the iteration series starts with a certain formula, determined by the pa

Image Traps is based upon Damien Jones' Orbit Traps Gradient but with many additional enhancements. It has image import capabilities. Image examples will be taken from from my website. The link is

This is a 3D raytracing formula with 60 3D plug-in formulas available. Two coloring formulas are available: 3D Fractal Coloring Gradient Progressive and 3D Fractal Coloring Direct Progressive.

Parameters and Options:
The main raytracer has a number of options and parameters. The main algorithm is based upon an article by Hart, Sandin and Kauffman for estimating the distance from a point to

For the Embossed Traps tutorial open Object Formula Switch Lite and load the the Switch Trap Embossed plug-in. In the Trap Parameters section note the Fractal formula plug-in, which is actually a specially designed Trap Shape that only works with Switch Trap Embossed. There are 104 to choose from. The default is Rose Range Lite and is closely modelled after a formula of Kerry Mitchell's. The Tra

For the Slope Lighting tutorial open Object Formula Switch Lite and load the the Slope Switch plug-in. Virtually any Switch formula can be used to apply the slope plug-in, but for this tutorial we will stay with Mandelbrot Julia Switch. The slope formula requires a specific coloring formula, called Lighting. There are several of them available in the Ultrafractal database. We will use Lighting wi

Plug-in Tutorial: Embossing

This tutorial will use Switch Emboss, which is a plug-in for Object Formula Switch Lite. Open Object Formula Switch Lite and replace Mandelbrot Julia Switch with Switch Embossed. Immediately following the new plug-in will be some text recommending some changes to the bailout settings. New parameters for Light Angle, Contour Size and Emboss Type will be visible. The

Background

This tutorial will be focused upon some formulas that I use frequently and the plug-ins they can use. Many of the plug-in types have multiple authors.

Formulas

Object formula plug-ins have enhanced the capabilities of Ultrafractal. Unfortunately the built-in switch capability to switch between Mandelbrot and Juli

Object Formula Switch has a number of options in the dual formula mode. Its possible to combine two divergent formulas, two convergent formulas, and a divergent with a convergent formula. The combination can be created by a variety of alternate iterations or by merging using any of several types of operations (addition, multiplication, division and much more). Bailout can be by either formula or

Internally, Lucy Goosey Switch uses two separate formulas. In the older versions switching between the formulas was accomplished using a modulus criterion applied to the number of iterations. This works well for an every other iteration switch but not for more complex switching. The latest version can use either modulus switching (the default) or more complex sequence switching.

Ducks switch works with the Switch formulas I described in the tutorial. For Ducks switch specifically the formula is derived from the Ducks formula sam.ufm with multiple modifications.

Ducky Plus

Ducky Plus extends the capabilities of the existing Ducky-formulas. Per pixel it can in one run follow various basic codes. These successive iterations take place in three steps:
From start to n1 ['End of First Step'] the first series of iterations,
from n1 to n2 ['End of Last Step'] the second series,
and finally from [n2 + 1] to 'Maximum iterations' the third and last

This tutorial will make extensive use of plugins for both the fractal formula and for the coloring formulas. All of the examples have more than one layer.

The first example is called Boxes, and the upr is on the forum website. It uses the Julia form of the Gopalsamy Switch fractal and uses 'smallest|imag(z)|' for the basic height. In Lighting with Textures the 'Soften edges' parameter checke
