Issues with particles editing using OBI Editor

So the white gradient overlay that got created (see screenshots) while editing particles property show the effect (coverage area) on the soft body? Could you please elaborate on this?

The gradient shows how the currently selected property varies over the softbody surface. For instance, if your selected property is "mass", the gradient represents mass distribution. Excerpt from the manual (visualization options):

Quote:The source mesh used to generate the blueprint is rendered. The currently selected particle property is used to drive vertex colors. You can use the range options in the visualization section (see below) to determine how property values are mapped to colors.

Reason am asking is to better understand when to delete versus editing - I understand both are not mutually exclusive obviously.

The main reason you'd want to remove particles is when you don't want the entire mesh to behave as a softbody. See the elastic character sample scene for instance: only the arms have softbody physics applied:

Adding particles won't prevent collapsing, what you want to do is increase the soft cluster radius. The blue links represent shape matching constraints. These are a type of constraint that tries to keep the overall shape of a particle neighborhood. See:
