Hello again Petras

Seems like you forgot to call AssignPIndex for the volume goal :)

IGoal volumeGoal = volume(m);
PS.AssignPIndex(volumeGoal, 0.01);
GoalList.Add(volumeGoal);

Hi Long Nguyen,

Thanks, it works.

But I would like to ask several questions about Kangaroo2:

1. When defining simple Goals like Springs, Anchors I can work with indexing:

GoalList.Add(new Spring(particle_index1, particle_index2, 1.1, 1));

But when working with more complicated goals I have to use PS.AssignPIndex :

PS.AssignPIndex(volumeGoal, 0.01);
GoalList.Add(volumeGoal);

It just how it works? One goal can use particle indexes (Anchors, Springs, etc.) others PS.AssignPIndex? Otherwise If I want to use particle indexes, I would need to make my own custom goal ?

2. I compared c# script with Kangaroo definition. The geometry in c# script moves in Z axis, the geometry in Kangaroo2 definition stays in the same positions and is inflated gradually.

How to make c# geometry stable?

I attached printscreen and definition.

Here's the recommended way to play with the Volume IGoal and K2 on meshes.
