Why is my .x3d export from Paraview not complete (in Client/Server)?

I am trying to export a scene from Paraview so that I can work on it in blender. Following instructions found on multiple sources on internet (example here, slide 9), one of the ways of doing this is by exporting a Paraview scene with the .x3d format. So, I try to do just that. In Paraview, I have some pathlines, with tubes around it, colored by velocity. I show these in Paraview, even select them in the tree, like this

Then File > Export Scene... > X3D Files.

After this, when I check the produced x3d file, there is no 3D data in it, as illustrated below (vi on the x3d file):

So.. what am I doing wrong here? I use Paraview 5.4.1.

Thanks a lot for any help!

Edit: I am trying to do this in client/server mode.

Ok, I found the solution, hopefully this can help others.

In Paraview, go in Edit > Settings... > Render View Then set the Remote Render Threshold to the max, as illustrated below.

PS: I found the solution here.
