If the normals always have to point upwards, you can force them by setting them manually in an attribute wrangle.
With this little line of VEX:

@N = set(0, 1, 0);

That way, it doesn't matter whether they're flipped or not.

Thanks Ecxter, that Fixed it!

HI All,

So I have an issue, in where I'm trying to create a procedural base outline tool. To go with the Indie Pixel Base builder tutorials.

The Problem I'm having is that when i use the sort SOP, the extract silhouette every so-often flips the normal's, as seen in the pics.

I've tried the Normal's, Facet and poly frame SOP's and to no avail, the normals still swicth.
