With the Cloner selected, switch to the mograph selection tool in the Mograph menu and select the clone you want to have control over.
When you make the selection, a “Mograph Selection” tag will be automatically added to the Cloner.
Now add a Shader effector to the cloner.
Drag the Mograph Selection tag from the Cloner to the appropriate field on the Effector tab of the Shader Effector.
On the Shading tab, set the channel to custom and select the “color” option from the shader selection button (down arrow before the empty field).
Set the color to white if not already there.
Now twirl open the shader and adjust the brightness control below the color until the correct texture from the multi shader is displayed on that clone.
