Configuring the Chunky Launcher¶
Before being able to render scenes, some actions must be performed in the Chunky Launcher.
If you downloaded the Chunky Launcher (Universal JAR), and this is your first time starting Chunky, then you must update Chunky. Otherwise, click Launch to start Chunky.
In the Launcher, click the Check for update button to make the Launcher check for an update for Chunky online. If an update to Chunky is available, you will soon see the 'Update Available' window:
Click the Update to New Version button to start downloading the required files. When the download process has completed, you can click on either Launch Chunky or Close. If you click on Close, you would need to click on Launch in the main Chunky Launcher window to launch Chunky.
Minecraft directory: If your Minecraft game directory (.minecraft) is located somewhere other than its default location, then you may also need to change this to point to your current Minecraft installation; otherwise, blocks rendered in Chunky will not have proper textures, and your worlds will not be found.
Memory limit (MiB): Chunky can use much memory depending on a number of factors. Many issues can be caused by Chunky not having enough memory, so raising the memory limit can solve these issues. The default of 1024 can be raised based upon how much memory your system has and how much is typically available. For example, if your system has 16 GiB (16384 MiB) of system memory, allocating up to 75% of that, which is 12 GiB (12288 MiB), is typically fine. You can allocate more; however, you may eventually encounter other problems.
You should not need to access Advanced Settings.
If the Launcher does not download the latest version or new snapshots, check the Update Site in the Advanced Settings panel. The URL changed with Chunky 2.1, so make sure it is set to
https://chunkyupdate.lemaik.de/. If you have used Chunky 1.x, it may still be set to llbit's update site. You can keep using that if you want to use Chunky 18.104.22.168
If you get an unchecked exception caused by
java.lang.NoClassDefFoundError: javafx/application/Application when clicking Launch in the Chunky Launcher, then double-check that the Java Options input field under Advanced Settings is populated by
--module-path "<path\to\javafx\lib>" --add-modules javafx.controls,javafx.fxml.2 3 This field is automatically populated if the Chunky Launcher automatically detects OpenJFX. If OpenJFX is added manually in the startup command, then the field must be populated manually.
Chunky 2.4.0 supports Minecraft 1.2.1 and above (i.e., pre-flattening worlds), so you probably do not need the old version anymore. ↩

Replace text within angle brackets
