Change Hardware Texturing Channel using Mel

global proc AEhardwareTextureChannelCB( string $attrTokens,
string $messagePlug )

// Get the material info node.
string $info = getMaterialInfo($messagePlug);
if ($info == "")
return;

string $channelMenuName = getChannelMenuNameFromMaterialPlug($messagePlug);

string $channelAttrs[];

// assume that it is set to 'Combined'. (bake the whole shader
// as if it was a texture)
//
if ($attr == "")
{
// In order to display all textures at once, we need to
// hook up the materialInfo node in a non-standard way:
// the "texture[0]" attribute is set to the shader (as opposed
// to a standard texture), and the texturePlug is set
// to the outColor of the shader.
//
connectAttr -f ($material+".message") ($info+".texture[0]");

string $texturePlug = getTexturePlugFromMaterial($materialPlug);

// Is a texture connected on this channel ?
//

if ($texturePlug != "") {
// Connect up the new texture to materialInfo.
//

string $node = getPlugNode($texturePlug);

if (size(`listConnections $node`) > 1) {
// It may be ambiguous for materialInfo to figure out which
// channel to display (for example, if a file texture is
// hooked up to both color and bump on a material). We
// make a connection to the "textureChannel" to specify
// which plug should be used.
//

connectAttr $texturePlug ($info+".textureChannel");
}

// Now let materialInfo do its thing
//

connectAttr ($node+".message") ($info+".texture[0]");
}
}

updateQualityMenu( $attrTokens, $messagePlug );

}
}

Script editor echo all commands these two lines of code when you change hardware texture from none to incandescence.

I'm trying to figure out the mel to set a shaders hardware texture channel.


AEhardwareTextureChannelCB "color transparency ambientColor incandescence normalCamera diffuse translucence" lambert2.message;
AEhardwareTextureChangedCB "color transparency ambientColor incandescence normalCamera diffuse translucence" lambert2.message;
