Cannot select scalar to vary radius of tube filter
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The tube filter has a "Vary radius" option that allows you to vary the radius of the tube based on a scalar or vector. However, you are not able to select the scalar or vector to use. Instead, the active scalar or vector is taken.
The tube filter should allow you to select the scalar or vector. Ideally, it would also automatically select scalars or vectors based on what variable the user selected.
