PCG Spline Issues

I am attempting to use PCG to build indoor environments. I’ve got the floors and ceilings working nicely but I’ve been struggling with the walls for a couple weeks now.

The issue I’m having involves the Z rotation of the points in the spline sampler. As you can see from these images, the point rotation doesn’t seem to follow any kind of strict logic and I can’t for the life of me figure out how to make these behave.

I have verified that the rotation of the spline points seems to have no effect on the rotation of the spline sampler data. Any help would be greatly appreciated.
