I have recently done an animation that required a 2d picture of a
circus tent to pop up from the ground in a comical way and the rest on
the ground. It is a plane object mapped with the picture and then clip
mapped with an alpha to reveal only the tent. The animation works well
but at random intervals the polygons on the tent plane beam out and in.
I tried extruding it into a 3d thin box type of plane and also used
double sided but the result is the same. The plane has limited poly gons
as I thought that a great deal would do nothing to a planar object used
in that fashion. I am under the feeling that this is an issue of
non-planar polygons. Anyone no how to fix my glitch???
