If the mesh plot is not added, the Pseudocolor plot renders correctly, but once the Mesh plot is added, the 'highlight' artefact remains, even when all the plots are deleted and Pseudocolor is re-added.\r\n\r\nI've attached three images that demonstrate using rect3d:\r\n  pc_alone: just the Pseudocolor plot before Mesh plot is added\r\n  pc_mesh:  after adding mesh plot, the back top edge appears 'highlighted'\r\n  pc_mesh_deleted: after deleting mesh plot, looks like the back face is 'elevated', causing the 'highlight' effect.\r\n\r\nIt may be due to use of *SetResolveCoincidentTopologyToPolygonOffset*\r\nand *SetResolveCoincidentTopologyLineOffsetParameters* \r\nby Mesh Plot's mapper.\r\n\n\nComments:\nI modified how Mesh plot is  mapped.  The output from the mesh filter is now two datasets, one for the mesh lines and one for the opaque polys.  Each assigned their own mapper, and actor properties contoroling color and visibility.  The custom vtk mappers have been removed.M       avt/Plotter/avtGeometryDrawable.CM       avt/Plotter/avtMapperBase.hM       avt/Plotter/avtActor.CM       avt/Plotter/avtActor.hM       avt/Plotter/avtMapperBase.CD       plots/Mesh/vtkOpenGLMeshPlotMapper.hM       plots/Mesh/avtMeshPlot.CM       plots/Mesh/Mesh.xmlM       plots/Mesh/avtMeshPlotMapper.CM       plots/Mesh/avtMeshPlot.hM       plots/Mesh/avtMeshFilter.CM       plots/Mesh/avtMeshPlotMapper.hM       plots/Mesh/avtMeshFilter.hD       plots/Mesh/vtkMeshPlotMapper.CD       plots/Mesh/vtkMeshPlotMapper.hD       plots/Mesh/vtkOpenGLMeshPlotMapper.CM       plots/Mesh/CMakeLists.txt\n\n"}}
