Material Viewer - Node Wrangler....where is the viewer?!

I have added the node wrangled plug-in, and I can see all the options in the properties menu when I press “N” in the node editor screen. The instructions say press ctrl+shift+click to open view…this seems to add a viewer node between the that node and the material output node…but I cannot see any way to view anything, there is no window showing me anything to look at. What might I be doing wrong?



Set the 3d view to Rendered

Thanks! I was expecting something to come up like when previewing in the compositor…brain not fully in gear :wink:
