Head primitive/maskng

Hi all.
I’m having a issue with the head primitive. When I mask the area and go to extract it it works fine but I’m still left with a sizeable mask thickness, previous Times I’ve done this it’s worked fine. I might be doing something wrong but just looking for some input

The reference of the extraction values has changed! Now the values are related to the WORLD! You have to enter values for the mask extraction of e.g. 0.005 or 0.021. Values such as 0.5 lead to the explosion! ! :grinning:
