AntoniaTiger, yes. Displacement actually adds "micropolygons" to the surface being rendered. To see this in effect, take a lo-poly cube or sphere and (in the Materials room), plug a noise node (3D Textures) into the displacement socket. Leave the value set to 1; set the rendering options to "Use Displacement", set "minimum bounds" to 1.1 and render. Marvel at the square/round hedgehog that appears:-)) One thing to be careful about when using displacement; where surfaces join together (eg the edges of a cube) ensure that whatever map/algorithm you use are virtually zero at that point, because otherwise you'll get gaps. Displacement acts along the normal of a surface, so if 2 surfaces are facing different directions, the displacements don't match. If they ARE in the same plane, then as long as the values match along the border, all should be OK. For clothing, since the displacement will usually be tiny, any gaps should be easily remedied in post-work. (no worse than having to fix those "extreme pose" distortions on an unclothed body..
