Parameters for Static Shadows

• Ground - floor height in world coordinates (mesh will be extruded to this height).
• Offset - offset of the interfering volume of shadows relative to the original.

  • "Active" for Mesh Renderers that will move and rotate.
  • "Skin" for Skinned Mesh Renderer.
• Click "Create" to create the shadow.
• Click "Remove" to remove the shadow (attention, before removing the component from the object, be sure to click the "Remove" button).
