I am trying to export some data I have in Paraview to blender. My data consist on a set of points with a point property. Those points are connected by lines.

I want to render this in Blender. Since my geometry is just lines, Blender can’t render this properly. I want to convert the lines to tubes to be able to export it as proper triangle geometry which Blender can render.

I have tried to add a Tube filter, but is disabled (grayed).

Use ExtractSurface filter first.
