var materials : Material[]

Description

All the materials of this object.

This is an array of all materials used by the renderer. Unity supports a single object using multiple materials; in this case materials contains all the materials. sharedMaterial and material properties return the first used material if there is more than one.

Modifying any material in materials will change the appearance of only that object.

Note that like all arrays returned by Unity, this returns a copy of materials array. If you want to change some materials in it, get the value, change an entry and set materials back.
