GeoSphere and Pick result

I'm trying to obtain pick result, in ray, from camera to my geosphere but no result.

Is that geosphere is not affected from picking calculation ?

Ray ray = new Ray(camera.getLocation(), camera.getDirection());
PickResults results = new BoundingPickResults();

Does it have a bounding volume? The kind of mesh should not matter.

Right, now…How to find wich triangles are "touched" by ray in the mesh ?

I'm trying with TrianglePickResults and TrianglePickData but .getTargetTris()  gives me nothing…isn't it strange ?

Are you placing your geometry on the collision tree. I some time ago read that to do triangle accurate picking you need this.
