Material Changes in Kitchen

Why when im changing the material of the kitchen cabinets , certain parts of the tall cabinets are not changing. Like the top , the base for the oven, the toe kick of the first tall cabinet…?

We cover it later on on the course. There are not parameters set up for it and I will show you how to add them

so for now in the homework do i leave the cabinets part old and part new material?

Yes
