Hello. I use Paraview to open a VTK ASCII tetrahedral unstructured grid file which has color scalars assigned per cell (tetrahedron). Everything is correct so far: I am able to see the different colors on the surface of the unstructured grid. That is, the boundary triangles are colored as they ought to be according to the scalars of the file.
The problem occurs when I apply the Extract cells by region filter. The different colors disappear and only one color is displayed for all cells. Is there a way to preserve the different colors per cell after the filter is applied? Regards, Panagiotis Foteinos
