Zbrush4 shadow box Alphas youtube tutorial

I have attempted to follow this tutorial as described in the video but I’m having a frustrating time as I just cannot get it to work
I’m using mask rect, rect stroke, brush alpha pattern (a psd greyscale file) however when I press Ctrl to apply the mask (0:24 in the video) it switches off brush alpha and just makes a rectangular shadow and rectangular 3d model ignoring the alpha mask.
It have also tried the existing alpha 53 and that does not work.
Can somebody explain what I am doing wrong, is there something I am missing? :confused:small_orange_diamond:cry:small_orange_diamond:(:angry:

Solved by trial and error:+1:small_orange_diamond:
Hold Clrl whilst selecting mask rect, rect stroke, brush alpha pattern at the same time puts it into a different mode
