QUESTION

My landscaping plan includes a water feature and I would like to be able to see through the water to the bottom of the pool.  How can I edit a library material so that it can be seen through?


ANSWER

Most of the materials in the library are set up to be opaque, so that they appear totally solid.  In some situations, though, transparency can be a helpful attribute.

In order to make changes to a material, though, it must first be copied into an unlocked library.


To make a copy of a library material

  1. Select Library> Library Browser  from the menu to open the Library Browser.


  2. Browse to a material in the Materials library category that you would like to make transparent.

    • A selection of water materials can be found at Materials> Landscaping> Water.


    • Right-click on the material and select Copy  from the menu that displays.


    • Scroll in the Library Browser to find the unlocked library User Catalog.

           In Chief Architect X3, use My Library.

           In Chief Architect X1, use User Libraries.


    • Right-click on the unlocked library and select Paste from the menu.  A copy of the selected material will now be found in this library. 


    To change the transparency of a material

    1. Right-click on the material copied into the User Catalog in the steps above and select Open  from the menu.


    2. In the Define Material dialog:   

      • Change the name of the material and replace it with something short and descriptive.

      • On the Properties panel, change the Material Class from its default of "Transparent" to "General Material".

      • Use the Transparency slide bar, or type a value in the edit box, to adjust the material's level of transparency. Click OK to close the dialog and apply your changes to this new material.


        * For the purposes of this example, we have set our modified water material to 60%

        Note: Transparency controls how opaque or transparent a material is. Most materials are opaque while some materials, such as glass, are partially transparent. In some situations, materials with transparency can slow down rendering speed.  A transparency of 0%, with the slider all of the way to the left, is completely opaque.




    To define transparency in Chief Architect X2 and prior

    1.   At the top of the dialog, delete the name of the material and replace it with a short, descriptive name.


    2. On the Render tab, click the radio button beside Advanced, then use the Transparency slide bar or type a value in the edit box to adjust the material's level of transparency.  A value of 0 will create a completely opaque material that cannot be seen through, 100 will be totally transparent and cannot be seen in 3D views.




    3. Click OK to close the dialog and apply your changes to this new material.


    4. When you apply this customized material to an object, it will display either partial or total transparency in 3D views.
