Hi All, I'm using the free tutorial by ctbram that explains how to create grills in Maya. It was all going really well until I assigned a paint effects brush to my curves that I had projected onto a surface (Paint Effects > Curve Utilities > Attach Brush to Curves). My problem is that I can't edit the pressure scale attribute located under the paint effects strokeShape. Changing this doesn't affect the stroke in any way.

Any help is greatly appreciated.
