existing shaderS?
 

At the install of maya I have installed the shader library ,too but where are all those pre installed shader?

What version of Maya do you have? I have 4.5, and their in the C:\Program Files\AliasWavefront\ShaderLibrary folder.

Ahh, I just learned this when I reinstalled Maya. Go to your Hypershade, () and in the low of the two boxes, are tow tabs. 'Work Area' and 'Shader Libray' Click on Shader Libray. and you have it.

:D thanks a lot...I have maya 4.5
