The particle collector was collecting some particles twice due to a tolerance extending the tracked path. This has been removed. The new tracking algorithm does not generate the same sorts of spurious tolerance-scale motions that the old one did, so this extension of the tracking path is unnecessary. Some particles were also not being collected at all as they were hitting a diagonal of the collection polygon and registering as not having hit either of the adjacent triangles. The hit criteria has been rewritten. A hit now occurs when the normals of the triangles created by joining the intersection point with the polygon edges are all in the same direction as the overall polygon normal. This calculation is not affected by the polygon's diagonals. The issue was raised by, and resolved with support from, Karl Meredith at FM Global.
