Changing Material Presets

[phyllisr]

Though my search did not get me a result, I suspect someone has tried this successfully. How can I change the material preset options? Modifying individual materials and making image files accesssible is not a problem but I would like to add a few images to the presets. Likke Cork. I know where the files are located (C:\Program Files\Autodesk Revit Architecture 2010\Data\Rendering\assetlibrary_base.fbm\Materials\...\Presets) but cannot figure out how to get it to appear. Thanks in advance.

I'm using 2009, but recently added some materials (jpegs) to the relevent "Presets" folder by simply copying to that folder. The files became available as materials as soon as I re-started Revit.... hope this helps.
