RR Block Model Custom Shading

In the Designer tab > Display panel > Block Model section > Shading dropdown > there is a preloaded list of automatic shadings for the level hierarchy and reserves fields. We can add to this list by configuring custom shading sets.

Create a simple custom shading:

Select the gear icon next to the Shading dropdown. This opens the configuration dialog.
Press the blue plus icon to add a new shading set.
Rename the shading to "Materials".
Drop down the Shading Field and select 'Parcel'.
Press the 'Create Entries' button to populate all parcel names.
Assign a colour to each parcel.
Press OK to accept.

Simple shading on material type.

Block model shaded by material type.

Create a complex custom shading:

Select the gear icon next to the Shading dropdown. This opens the configuration dialog.
Press the blue plus icon to add a new shading set.
Rename the shading to "Ranges".
Select the 'Complex' tab to open the code editor.
Paste in one of the sample code snippets located below.
Press OK to accept.

Shading high Fe (pink and blue) vs. high Al (grey and blue).
