public void CopyAndAddConnectedAsset(Material sourceMaterial, Material targetMaterial)
{
   Document doc = targetMaterial.Document;

   // Get the appearance asset of the source material

   ElementId otherAppearanceAssetId = sourceMaterial.AppearanceAssetId;

   AppearanceAssetElement otherAssetElem = doc.GetElement(otherAppearanceAssetId) as AppearanceAssetElement;

   Asset otherAsset = otherAssetElem.GetRenderingAsset();

   // Get the connected asset of the source material appearance asset (that contains the bitmap)

   AssetProperty otherGenericDiffuseProperty = otherAsset.FindByName(Generic.GenericDiffuse);

   Asset otherGenericDiffuseConnectedAsset = otherGenericDiffuseProperty.GetSingleConnectedAsset();

   using (Transaction t = new Transaction(doc, "Change a connected asset by a copy"))
   {
      t.Start();

      using (AppearanceAssetEditScope editScope = new AppearanceAssetEditScope(doc))
      {
         ElementId appearanceAssetId = targetMaterial.AppearanceAssetId;

         Asset editableAsset = editScope.Start(appearanceAssetId);   // returns an editable copy of the appearance asset                   

         AssetProperty genericDiffuseProperty = editableAsset.FindByName(Generic.GenericDiffuse);

         Asset genericDiffuseConnectedAsset = genericDiffuseProperty.GetSingleConnectedAsset();

         if (genericDiffuseConnectedAsset == null)
         {
            // Target material has only a color for �GenericDiffuse�
            // This will assign a bitmap to it instead
            // by making a copy of the asset and use it as connected asset
            genericDiffuseProperty.AddCopyAsConnectedAsset(otherGenericDiffuseConnectedAsset);
         }
