I am trying to employ Surface LICs for the visualization of flow features, but the lines that I get don’t make much sense to me.
Strikingly, the LIC texture does not rotate with the surface in regions with low magnitude (blue):
Also, the texture is unaffected by the choice of input:
Am I missing something? I have never used LIC before, but I went through pretty much all the settings I could find.
I am using the current binary release ParaView-5.10.0-MPI-Linux-Python3.9-x86_64.tar.gz
This is the data I am using in the demo (Provided by Boston University TechWeb ):

This is expected behavior
Also, the texture is unaffected by the choice of input:
Works well here, without any issue:

weird, now that I tried it again, it also works for me.
And the result looks reasonable also when rotating the view.

mh but here I have the issue again:
when looking from the inside, the LIC-structures are pretty much aligned with the x-axis, when looking from the outside, they have a -y component.
I am loading the plugin with
LoadPlugin('/soft/ParaView-5.10.0-MPI-Linux-Python3.9-x86_64/bin/../lib/paraview-5.10/plugins/SurfaceLIC/SurfaceLIC.so', remote=False, ns=globals())
before building the pipeline.
When the bug appears, the LICs react to the Color input instead of the Vectors input:

please share steps to repro
