Use TransformNode on SolidParticleSystem

I receive an error, when use TransformNode on SolidParticleSystem.
https://www.babylonjs-playground.com/#WCDZS#139

var plane = BABYLON.Mesh.CreatePlane(“plane”, 5, scene);
var CoT = new BABYLON.TransformNode(“root”, scene);
plane.parent = CoT;
plane.rotate(BABYLON.Axis.X, -Math.PI/2);
var SPS = new BABYLON.SolidParticleSystem(‘SPS’, scene);
SPS.addShape(CoT, 1000);

That’s the expected behavior.
The method addShape(mesh, nb) expects a mesh to be passed, something with a geometry : vertices, indices, normals and maybe also uvs and colors.

Thank you!
