3D & Animation Freehand Polygon Drawing

In UnrealEd I am following a tutorial to create freehand polygons:

Select texture /
Select freehand polygon drawing icon /
Select Ctrl + right-click to place minimum of 3 vertices in top viewport /
Release Ctrl + right-click in viewport space to 'create brush' from dialogue
Enter depth value to extrude created shape to that depth
Select 'Add' to add the brush to world

I follow this to the letter and all I get is a little red cross after entering the depth value, which disappears when I select the 'Add' icon.

I am using grid size at 16 and only use depth values to multiples of 16 - all vertices snap to grid nicely.

What am I missing?
