I want to know what you think about this. I am using a plane with 64 x 32 segments to make a  3D shape (please, no arguments about whether this is a good idea), and I have realised a problem. The segemnts are square not triangular, and mathematically, it is possible for four points to not be along the same plane. I want to know what happens to segments which are not planar, whether I should fix this by making them all triangular (a triangle can only be in one plane), and if there is a quick way to do this.

Yeah, I just worked out the Edit Triangulation thing when you click on Polygon in the editable poly thingum. Is there an easy way to make the triangulation lines into edges though, cos that wold make my life so much easier.
