Yup, I get that, Doctor.
I was referring to the very light selection lines (or rather pixels) surrounding the actual dots in your first image, not the thick black line in your second image.

The reason I mentioned post-filter settings is because after installing SR3 in Poser 7 I got bucket-boundary problems when using a post-filter setting higher than 1 pixel. Now I think about it, this was mainly when using the 'sinc' post-filter.

Note: I did not mean texture filtering, but render post-filter settings.
