Time needed: 5 minutes.
Please use always 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.
Use the jwildfire.exe to start the launcher.
Under Mac OS use the start_mac.command to start the launcher.
Under Linux use the start_linux.sh 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 the most cases you cannot render large images with those settings because not enough memory is 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
It 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 I have no way to test this) you can manually add it. You must do this only 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 here specified if JWildfire is already running. I. e., 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 start 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 launching 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.
