Hi Faraz, The vector graphic export in VTK/ParaView has always been tricky and, unfortunately, somewhat flaky. Many objects, most notably those that have textures applied for color, do not come out correctly when exporting through the GL2PS library, which VTK/ParaView are currently using. These objects can only be exported as a raster image, since GL2PS has no way of getting texture information out of the OpenGL feedback buffer.
With newer versions of OpenGL, the feedback buffer used by GL2PS has been deprecated, greatly reducing the usability of the export library. Because of this, all 3D geometry is currently rasterized when using the new OpenGL2 backend to VTK/ParaView. Right now, the best you can reliably expect is a rasterized 3D geometry, with vectorized text. 2D charts in ParaView should export well, but any general renderview scenes will be mostly rasterized. We're hoping to improve this in the future, but no work has been scheduled to improve 3D geometry exports. One thing that *might* help is to play with the the "Interpolate Scalars Before Mapping" option on older versions of ParaView while exporting. This can prevent texturing and make it possible for GL2PS to extract the necessary information, but it will not make a difference when the OpenGL2 backend is used.
