Obi softbody crashes after setting inverse masses

[Jschol]

Hi all,






I am trying to set the inverse masses of my obi softbody however, it crashes when settting it to a non 0 value with the error:




transform.position assign attempt for 'Cluster0' is not valid. Input position is { NaN, NaN, NaN }.



UnityEngine.Transformet_position (UnityEngine.Vector3)



Obi.ObiSoftbodySkinner:UpdateBones (Obi.ObiActor) (at Assets/Obi/Scripts/Softbody/Rendering/ObiSoftbodySkinner.cs:130)



Obi.ObiActor:Interpolate () (at Assets/Obi/Scripts/Common/Actors/ObiActor.cs:1207)



Obi.ObiSoftbody:Interpolate () (at Assets/Obi/Scripts/Softbody/Actors/ObiSoftbody.cs:289)







I am setting the inverse masses like this:

Code:

    public void setGroupInvMasses()
    {
        foreach (int index in obiParticleGroup.particleIndices)
            obiActor.solver.invMasses[obiActor.solverIndices[index]] = inverseMasses;
    }

I also call:

Code:

ObiSoftbody.UpdateParticleProperties()

after setting the inverse masses.



Is there something I miss?




I am not sure if it is relevant but, I also change some of the shape matching constraints of the body.





Kind regards,



Jasper
