Help particle properties at Runtime

[Nightfall]

Hi!

See: http://obi.virtualmethodstudio.com/manua...aints.html

I was writing code based on a link like below

Code:

var obiSkinnedCloth = assetObject.AddComponent<ObiSkinnedCloth>();
var blueprint = ScriptableObject.CreateInstance<ObiSkinnedClothBlueprint>();

blueprint.inputMesh = meshFilter.mesh;
blueprint.GenerateImmediate();

var actorConstraints = obiSkinnedCloth.GetConstraintsByType(Oni.ConstraintType.Skin)
    as ObiConstraints<ObiSkinConstraintsBatch>;

var solverConstraints = obiSkinnedCloth.solver.GetConstraintsByType(Oni.ConstraintType.Skin)
    as ObiConstraints<ObiSkinConstraintsBatch>;

var actorSkinBatch = actorConstraints.batches[0];
var solverSkinBatch = solverConstraints.batches[0];

but I encountered a NullReferenceException on the line
How can I fix it?

Code:

var actorSkinBatch = actorConstraints.batches[0];
