[Paraview] x3d geometry export garbled?

[Cook, Rich]

I have looked closer at the image.  What first looks like the tiles are out of order is not the case.  What I believe is actually happening is that a different color map is being applied to each tile.  So the problem is in the "colors" section of the x3d file.  You can see this by looking at the patterns across the "tile" boundaries in the attached image.  The patterns are continuous but there is a discontinuity in the colors being applied.  For example, the green square in the image surrounds 9 tiles which share such a pattern in the image, kind of shaped like an ameoba.
I suspect that the part of the paraview code which assigns colors is not savvy about the idea that there are 16 processors and so is using a local coloring scheme.

Hi,
I have been trying to get paraview to play nice with blender.  Specifically, I'd like to export an x3d file which blender will draw nicely.
I was able to do so from a dataset when reading the data locally, but to do so requires some awful contortions.  I have to export the data first from VisIt as a set of VTK files, then read those in with paraview, then export as x3d, so blender imports them as a set of objects, and it is difficult to color all those pieces in blender.  So I'd like to have a more direct way to do this.
What happens in parallel is that if I "Export Scene" of a contour that looks like this in paraview:

The resulting x3d object displays like this in blender:

I believe that this means that Paraview is exporting the data out of order.  But there may be ambiguity in some specification.  Can someone help with this?
Thanks!
