How can I change Shader type

[fuzin]

How can I change Shader type eg. From lambert to something lyk
blinn or anistropic.......

[thnkr]

There's a lot that goes on when you do that

look up
whatIs AEshaderTypeCB;
AEshaderTypeNew.mel is where all the procs are defined that handle this;

a bit of copy and past ought to be enough though,

the example shows how to turn blinn3  into a lambert.

proc disconnectMaterialInfo( string $shaderNode,
        string $newShaderNode )
{
        $materialInfoNode = getMaterialInfo($shaderNode);
        if ($materialInfoNode == "")
        {
                // The materialInfoNode doesn't exist... fail silently.
                return;
        }

        disconnectAttr ($shaderNode+".message") ($materialInfoNode+".material");
}

proc string getMaterialInfo( string $shaderNode )
{
    string $connections[] = listConnections ($shaderNode+".message");

    for ($item in $connections)
        if (objectType $item == "materialInfo")
            return $item;

    return "";
}

string $shaderNode = "blinn3";
string $replaceNode = createNode lambert;

disconnectMaterialInfo($shaderNode, $replaceNode);
replaceNode $shaderNode $replaceNode;
