This isn’t particularly a bug but I am almost certain it is a program error. The mod matrix sources offset defaults to -100/-200 instead of 0. It is a bipolar parameter that seems to default in a unipolar manner. I assume this is a mistake.
- Open an initialized program in Halion.
- Navigate to the edit/zone tab.
- Scroll to mod matrix.
- select any mod matrix source.
- Hold Ctrl and click Offset. At this point the Offset will go from 0 to a negative value instead of centered.
