Tip 001: Colors in the Flame-editor

You have some nice gradient, but a small part is odd? Enter Gradient-tab and press the Edit gradient button.
Move the left color-marker to the left of the part of the gradient you want to remove.
Move the right color-marker to the right of the part of the gradient you want to remove. Press the Fade-button, now left colors is faded to right, and the odd part is removed.

Tip 002: Preferences

You may customize a lot of things according to your needs in the Preferences-window, for example paths or default-parameters for certain functions.

Tip 003: Java heap space

The common error "Java heap space" means the software ran out of memory.

The software only uses the amount of memory you specify in the launcher. So, often it makes sense to start the program again and increase the value "memory to use" in the launcher (if your system has memory left)

To reduce the required amount of memory you may reduce the render-resolution.

Tip 004: Solid rendering

When realtime-editing of a flame with solid-rendering appears too slow, just turn off solid rendering temporarily. Continue editing and finally turn in on again to proceed.
This works especially good for editing DOF-setting. Because they appear in non-solid-mode in realtime, while DOF is a post-processing-effect in solid-rendering-mode, i. e. does not appear in realtime-editing.

Tip 005: Parametric plots

There are many presets (formulas + variable ranges of interest) included in the parplot2d_wf-variation.
To switch between them change the "preset_id" parameter (range: 0...currently maximum available preset).
To edit your own formula turn off preset_mode by setting the parameter "preset_id" to some negative value, e.g. -1.

Tip 006: Memory

You may see both the available and occupied memory (RAM) in the "System Information" window.
Some memory is occupied by caches in order to accelerate future calculations. For example, Bitmaps, Fonts and Meshes are hold in the cache.
You may clear the cache at any time in the "System Information" window, in order to free memory.
