Quote - Are you sure those are single-sided polygons? It looks like classic poke through of a double-sided polygon. If that is the Poser "Cloth Plane" then you shouldn't be using this trick. That prop is double sided - there are different polygons on each side and you can assign separate materials to them and just color them like normal. For double sided props, set up two material zones, one for each side, and apply a small amount of constant displacement to both materials so there is no poke through.

i can not find material zones.
