Does anyone know how to disable visibility of specific layers in the GUI? For instance: If i want to disable all visible layers I will do.

gui::show "Layers/*" visible false

But when I try to disable only layer 'metal1' it doesn't detect it.

gui::show "Layers/metal1" visible false

Error message: [ERROR GUI-0013] Unable to find visible display control at Layers/metal1. [ERROR GUI-0070] Error: write_images.tcl, 25 GUI-0013

which PDK it is?

Thank you so much.
