From CC to Remask Copy layer > Remask 5 > Studio 2 Effect Blur
Actual mask seems to be ok when came out from Remask 5 but result show Compute pen area

Use the Keep, Cut and Compute brushes to refine the mask after pressing Compute Mask and then you have the option to use the other 3 brushes to refine it further. Keep = White, Cut = Black and Compute = Shades of Grey
