[Paraview] AMR Cut Plane

Hello Paraview Users,

i am recently working with vtkOverlappingAMR. i set up one of this
data sets using the "Image to AMR" filter in paraview, which basicly
creates an octree with 4 levels and 512 blocks on level 4 in my setup.
so i basicly converted mydata.vti into mydata.vth.

now i want to use mydata.vth in order to quickly calculate the result
of an arbitrary pipeline and save time adjusting the parameters of the
pipeline. i want to adjust the parameters on level 0 and then increase
the level to see the full resolution result.

for example i have the pipeline: mydata.vth (vtkOverlappingAMR) -> AMR
Cut Plane. now i move the cut plane and apply to see the result. when
increasing the level from 1 to 2 in the reader i get a strange result.
it looks like paraview doesnt remove the regions in which the amr
levels overlap. this means the amr cut plane cuts out the data on
level 0 and on level 1. Since Image to AMR creates an octree in which
all lower levels are overlapping with higher ones, the lower levels
always cover the higher resolution results when setting the level
above 1 in the amr reader.

how can i fix this?

Best regards,
Henry
