Just another thing I noticed. In the .robo file attached I have the same green blob I am trying to deal with and I choose a black mask for this to help detect this blob.
However, I wanted to make this blob bigger, so I decided to use the Erode feature. When I do this, however, the sides of the screen start to erode too (see attached picture file)
Is this supposed to happen? Is there any way I could stop this from happening please?
