 ## How to generate the textures.
 
-Make sure to have a Java runtime environment of 6 or higher installed on your computer. The easiest way to run this program is just to double click the .jar file, which will generate and save all textures to a folder named "GeneratedTextures". The .jar file can also be run from the command line. Doing so will allow you to see log output when generating the textures, which can be useful if you need to debug anything. When this program is run from the command line, the "GeneratedTextures" folder will be placed at the current directory that your command line is in. The command line parameters you can pass are:

When this program is run from the command line, the "GeneratedTextures" folder will be placed at the current directory that your command line is in. The command line parameters you can pass are:
 
 - -multiThreaded (boolean b): If b is false, texture generation will be done consecutively on a single thread. Otherwise, each texture generator will be run on a seperate thread. This should not cause any differences in the generated textures.
 - -nonDeterministicFrames (integer n): Generates n frames of each non-deterministic texture. Otherwise, no non-deterministic textures are generated.
