This is what the brickdata looks like on the client side.
   new fxDTSBrickData() {
      brickFile = "Add-Ons/Brick_1RandomPack/2x2OctoPlate.blb";
      topArea = "4";
      bottomArea = "4";
      northArea = "99";
      eastArea = "99";
      southArea = "99";
      westArea = "99";
      canCoverTop = "0";
      canCoverBottom = "0";
      canCoverNorth = "0";
      canCoverEast = "0";
      canCoverSouth = "0";
      canCoverWest = "0";
      hasPrint = "0";
      category = "Rounds";
      subCategory = "Octagonal";
      uiName = "2x2 Octo Plate";
      iconName = "Add-Ons/Brick_1RandomPack/2x2OctoPlate";
      brickSizeX = "2";
      brickSizeY = "2";
      brickSizeZ = "1";
      indestructable = "0";
      alwaysShowWireFrame = "0";
      isWaterBrick = "0";
   };
So I assume he wants a script that will automatically generate the brick icon, replace the current brick icon that the server provides with the client-sided generated one.
I'm not even sure if you can generate a brick icon in Blockland, maybe using a third-party program you could, but not in Blockland...
