Launching JWildfire

What you'll see when JWildFire starts

The first thing you'll notice when you start JWildFire is the initial "Welcome to JWildfire" (version No. and compiled date) window opening up...

This contains the Java Environment startup options, with a couple of optional settings.. JWildfire is just as happy working in 32bit mode as 64bit (optimal if your OS supports it).

When you are happy with your settings click on "Start"!

Shortly after this window disappears, you'll see the main "Welcome to JWildfire" window open with the main JWildFire interface behind it...

Meet JWildFire!

Thanks for your patience... I know it may have seemed like a lot of steps to get here but you shouldn't have spent more than 5 minutes or so.

Now it's time to show you why it was worth it!

Alternative Ways of Starting JWildFire...

In the unlikely event that using the "JWildfire.exe" file isn't starting up the software properly, there are alternatives...

These alternatives are found in your JWildfire installation folder. The first option is using one of the supplied platform specific start-scripts available in your installation folder:

"start_windows.bat", "start_mac.command" or ""

Alternatively you can use the "j-wildfire-launcher.jar" file instead.

If you use any of these alternative startup methods you could just create the shortcut, as described Here!, for the alternative file instead of the "JWildfire.exe" file...

More technical information about the launcher

Try not to start the j-wildfire.jar directly

Please always use the official launcher to start JWildfire. The launcher can be executed by any Java runtime and can be started with any options. The task of the launcher is to launch the main software with controlled options and to reserve enough memory.

  1. Your First Option is to use JWildfire.exe to start the launcher. Mainly because the executable file also contains a suitable Icon, which is used when you create a shortcut.
  2. Alternatively:
    1. under Windows use the start_windows.bat to start the launcher.
    2. under Mac OS use the start_mac.command to start the launcher.
    3. under Linux use the to start the launcher.

If this doesn't work or if you have another operating system not listed here, just start/open the j-wildfire-launcher.jar directly.


PLEASE DO NOT START THE j-wildfire.jar DIRECTLY! If you start the j-wildfire.jar directly, then JWildfire is started with default Java options. In most cases you cannot render large images with those settings because enough memory is not reserved at startup. So even if you have plenty of memory it can not be used for rendering this way. Additionally, the wrong settings may cause slower rendering.

How the Launcher works

The Launcher analyzes certain system settings to locate java runtimes on your system and automatically selects the most recent one.

You can override the automatically selected version by selecting another entry in the listbox.

If the scanner did not find a java runtime (probably on Macs as we have no way to test this) you can manually add it. You only have to do this once, of course.

The memory setting lets you specify the maximum amount of memory in megabytes to use. This memory amount is only allocated if required but there is no way to allocate more memory than specified here, if JWildfire is already running.

So you must choose this value wisely.

Example: 6000 MB should work fine to render images in high-end quality for print.


The launcher works in two ways: regular and debug mode. In regular mode it just starts JWildfire and shuts down itself. If you face any problems (i.e. JWildfire does not start) please activate the "Debug" checkbox. This forces a traced launch where log messages are recorded and displayed at the "Log messages" tab. You can easily copy those messages into the clipboard by using the "To clipboard" button and then report them for further assistance.
