Actually, on thinking it over, I disagree with you on both points [:D]

It would be awkward if I had a sloping wall (with a colour on one side) sloping the wrong way. And, if, using "Reverse Walls", it was flipped on both X and Y axes.

Of course, it would be nice if "Reverse Walls" had the option of which axis to flip it in.

Thanks anyway. It's nice seeing so many talented people writing plugins here. And even the base SH3D is getting more and more solid every time. [:)]
