SU Particle Tool
SU Particle Tool is a command-line tool used to convert binary particle files from Sonic Unleashed (.part-bin, .p-mat-bin) into editable text files (.particle, .p-material).
Usage
SU Particle Tool can convert from binary files to text files and vice-versa by dragging and dropping the corresponding files onto the tool, or by passing the path to the file in a command prompt. Converting text files back to binary files is not necessary, as the game recognizes both formats and will load them.
Note
Using append archives (+Archive) with .particle and .p-material files is not recommended, as the game will sometimes load the binary variants instead based on when the append archive was loaded.
