the screen shot shows two objects that were constructed in the same workshop dgn file, they have the same color - 21-, and the same material applied via the family & parts rendering section. Yet they are very different, one is almost black, the other is the proper gray. These items are compound cells, so I wondered if part rendering doesn't work inside a compound cell. So I copied the cells adjacent, exploded them and even applied the same material - cast iron- manually to some of the components. As you can see, no change. Am I missing something as to how to work with parts and materials?
