Tip Title:      editing a duplicate material render appearance effects both the original and the duplicate material

Issue:

In Revit when setting up render materials often you will make a duplicate of an existing material. Usually you will then edit the duplicate to suit the material requirements of the duplicate material. However if you change the appearance properties of the material you will find that the duplicate and the material from which the duplicate was made will be the same. So in effect the duplicate cannot be used as a different material in a scene.

1. create Duplicate
2. Duplicate inherits appearance properties and assets of the original meaning changing the asset properties in either the original or duplicate will affect both the original and duplicate

Solution:

When in the edit material dialogue box and you go to the appearance tab you will need to make a duplicate of the asset used for render appearance in the duplicate material. The act of duplicating material references same material rendering asset as defined in the original material. By duplicating the appearance asset you separate the two material rendering assets in the duplicate and the original:

1. Edit the appearance of the duplicate material. Click duplicate asset.
2. Change the properties of the duplicate asset.

Once you have duplicated and edited the duplicate asset you will no longer experience an edit affecting both the duplicate and the original:
