Dye Regions
Used for fluid motion tracking.
- Dye regions can only be spherical in shape.
- If a particle passes through multiple dye regions, it will adopt the color of the last dye region through which it passed.

Note: If both
dyeregion_rad and
dyeregion_radodx are present, the latter
takes precedence.
