Hi Ken, Thanks for your feedback and sorry for my late reply. Somehow I didn't get this message and only found your reply after searching in my mailbox. I tried various values for the Z Shift, increasing it by one order of magnitude until reaching a value of 200, restarting in between changes. This didn't help. I haven't really made any other changes in ParaView settings. I even restored to defaults a couple of times.

Hi Ken, Thanks for the detailed reply. I could not get anything out of the settings dialog as per your suggestion. Did you have a combination of those settings that might work for my files? I can also see the image you sent; that's usually fine. However, I typically apply a Threshold filter to the _basic_ files (Scalar: alive; min: 0.1; max: 1). In this case, the _basic_ object is always drawn in front of the _broken_joint_ object. In addition, I visualize dozens of these files every day so Transforming every single object is a bit tedious.

[Paraview] ParaView 5.x not showing all objects available in Pipeline Browser
Hi, I use ParaView to visualize data of our simulations using the Unstructured Grid data format. Up until ParaView 4.x everything worked fine: we typically visualize one set of data files as Surfaces and another as Wireframe. The Wireframe dataset refers to "fracture lines" in our simulations. See below how the simulation looked like in PV version 4.x. You could clearly see the line around the boundaries of the model. [image: Inline image 1] However, in PV 5.x the lines are not fully visualized as if they're hidden below the other data object: [image: Inline image 2] I've tried a few versions of 5.x but they all behave similarly. Does anyone know what might be going on here? Is this a bug / removed featured from the new version or should I do something different with 5.x? I've noticed that this issue does not happen consistently. I've seen the issue on both Linux Mint 17.3 (64 bit) and Ubuntu I've attached two example VTU files. Please visualize the second file as Wireframe (_broken_joint). Below are two large VTU files. https://www.dropbox.com/s/kzt4jq1wbwfua4j/out.zip?dl=0 Can someone else reproduce this issue? I'd really hope to start using ParaView 5 since it finally has the long-missing Reload Files options!

Re: [Paraview] ParaView Seg Faults when running Animation in a Programmable Filter
After a lot of debugging, it turns out the issue is with the SetCells function of the vtk unstructured grid.

Re: [Paraview] Programmable filter, looping over time steps and reimporting inputs
Thanks Utkarsh for your reply. I've gone through the blog a few times
already but I still don't understand the whole procedure. I even tried
to just run the example in the blog in a Programmable Source but it
doesn't work ('No module named numpy_interface'). Part of the issue
could be that I still don't fully understand the RequestInformation,
RequestUpdateExtent, and RequestData bits of the filter.
The input data that I'm working on in the pipeline (vtk unstructured
grid) already have different time steps. How can I update the values of
the inputs for the different time steps?
Thank you,
Omid

However, the input data is still from the time step where I first

How can I update the inputs from within my for loop or how can I

Filter handle my situation? If not, what is the alternative?
