Hi Psygorn,

That could happen if the 10 points were not spaced evenly across the distance. That would then create some compression or expansion in the result since the surface parameterization would not be uniform across the base plane.

For base planes it's best to generate simple bilinear surfaces made up of only 4 corner points instead of made up of more points. That kind of surface has the most simple and predictable kind of parameterization to it.

No, not currently. There is usually not a single defined unwrapping without distortion for a general curved surface.

Like Phiro wrote above use the "Flip surface normal" option in the Flow command to deal with this.

You can accomplish this currently by positioning your object above or below the base surface by your offset distance.

I think it's on this thread here:
