Chunky uses a lot of memory. If Chunky has too little memory to work with it may slow down to a crawl or crash. The memory limit can be increased in the Chunky Launcher.
Rendering using the command line (Headless Mode)
It is possible to render a scene from the command line. First set up a scene using the GUI. Don't forget to save the scene. Then run the following on the command line:
java -jar chunky.jar -render SceneName
Where SceneName is the name of the scene to render. You can read more about headless rendering here.
Shutdown when render completes on Unix-like Systems (Mac OS X, Linux, BSD)
In the Advanced tab of the Render Controls window, you can check the checkbox that says "Shutdown when render completes" to shut down your computer when the set SPP target is reached. (This can be toggled while rendering.)
On Unix-like systems, the
shutdown terminal command has to be run as root
sudo. For various reasons, Chunky cannot prompt for the password to
sudo, so you must configure your system to allow the command to run without a
Open a terminal (such as bash) and run
sudo visudo, providing your password.
Add the following line at the end of the file: (press Insert to type)
%user_name ALL=(ALL) NOPASSWD: /sbin/shutdown
user_name with your username.
Press Escape, then type
You may need to restart or log out and in for this to take effect.
This will only allow
sudo shutdown to run without a password; no other
commands run with
sudo will be affected.
Hacking on Chunky
To build Chunky you will need Apache Ant and Perl. Chunky is built using an
Apache Ant build script found in the project root directory. The
builds Chunky and outputs binaries to the
Chunky is split into four projects:
- chunky - main Chunky project
- lib - common code required by the other projects
- launcher - the launcher
- releasetools - Ant task for building releases
If you want to hack on Chunky itself you will need to set up two projects.
Eclipse project files for
lib are included. It should be
fairly simple to set those up in Eclipse. You will need to add a dependency
The Google Java style guide should be followed for new code (2 spaces for indentation, no tabs). If you want to contribute code to Chunky please make your code look similar to the rest of the code, and refer to the style guide when in doubt.
More information about Chunky, including a short getting started guide and rendering tips are available at the Chunky Documentation page.
