You don't need to have squidnodes but it is assumed you do
Installing is simular to squidnodes,
- Download the Eyelids addon.blend file
- Save the file to somewhere that you can access easily
- Either create a new blend file, or open an existing one
- Under the "File" dropdown menu, select "Append"
- Locate the Eyelids addon.blend file
- A folder labelled "NodeTree" should be present. Click into this folder
- Select only Eyelids(squidnodes addon) inside the folder and tick the "Fake User" box on the right hand side of the file dialog
- Click "Append"
- Now you can add it in just like the other squidnodes
note: There are no input textures
