Lighting on the Slice representation had the undesirable effect of darkening the slice with the default light, which is off center with respect to the view and focal points. We assume the common use case for this representation is to view the data as directly as possible to match colors on the slice with colors in the color legend. To better support this use case, lighting is disabled for this representation.
lighting is not disabled for slices in version 5.6 and 5.7.
You will notice that the shade of blue changes depending on the viewing angle although it is supposed to represent the one blue associated with the value that is visualized on the slice.
I know that I can turn off lighting globally by dropping the following lines into the python console,
To disable lighting on the output of the Slicefilter as you have produced it, you can set the Diffuse lighting term to 0 and the Ambient lighting term to 1 in the Lighting section of the Display properties in the Properties Panel.
Okay I see, so to be able to view multiple slices I will have to add multiple ExtractSubset filters and switch the representation of each one of them to Slice.
On the other hand there is still no way of obtaining a non-lit slice that is not aligned with the coordinate system.
From my point of view it would make more sense to add a “Turn-Off-Lighting”-checkbox to the properties-tab of any object.
oops
