	The trace setting determines how far off of the low poly surface that a ray cast will look for triangles in the high poly surface. It is expressed in fractions of the largest bounding axis. Tracing speed goes down rapidly as this is increased, but if your high poly geometry isn’t showing up in the normal map, you may need to increase this to 0.1 or more. The best solution is to try very hard to have the low poly version be a very close match to the high poly version.

			Note that you must also make sure the low poly and high poly occupy the same basic space (ie, their origins are the same). Otherwise the rays won't reach your highpoly model.

	The lowPolyModel must have texture coordinates on it, and care should be taken to make sure the mapping is as good as possible. Before doing a RenderBump, test the model in the game with "r_showTexturePolarity 1" and "r_showEdges 1". Make sure that there aren’t any texture seams that aren’t absolutely necessary, and that there are no overlapped texture projections.
