Skinned mesh and bounds

Hi! With megafiers, my skinned mesh gets deformed. But I can’t get its bounds update properly. Works only for static mesh. Things like:

this.GetComponent().sharedMesh.RecalculateBounds();

gives always the same result, while even at property inspector I can see actual mesh visually changed. Any input on this?

Update When Offscreen fixes that, don’t mind question anymore
