Gett all materials from types

Is it expected to not receive materials from some types but only from element instances?
For example (0;0) is a roof and I thought that I can get the material from the type, where materials are specified, but I receive empty branch.

I get material from the type and instance for Basic Wall, but I don’t get it from the Floor.

Hi Barden00,

Those are compound structures, you’ll need to get the Host Type and then deconstruct the Layers to access via Type.
