[Paraview] How to visualize multipart/multiblock models

[Utkarsh Ayachit]

Currently there is no way to hide-show individual blocks in a
multiblock dataset or assign colors to them. However, you can apply
the "Extract Block" filter to extract each individual blocks and then
apply colors to them or show/hide them.
