Extract blocks rendered incorrectly
I have a multiblock dataset produced by Flag, which have three material blocks. When I extract each of them individually, then step through time, it produces odd rendering results. This is using Paraview 5.9-RC2.
After looking into it more, I think the root cause is that for the first timestep, the blocks in the dataset are split into different number of partitions. In the first timestep, the 'top' block is split into two partitions. In later timesteps, the 'top' block is split into 4 partitions. Probably related to #20366 (closed).
Below are screenshots of the dataset at the second timestep. The first one is showing the individually extracted blocks, which is rendered wrong. The second screenshot is showing the corresponding blocks from the original dataset, without using the Extract Blocks filter. It renders the blocks correctly.
How to reproduce:
- Load the dataset
- Apply the Extract Block filter three times, extract the 'top', 'middle', and 'bottom' blocks
- Step through time to the next timestep
I can email you the dataset.
