Review comment (suggestion):
This is what I meant in the previous suggestion when I mentioned that `shader_attributes` is used in a strange way: it enters the function as a list of names (strings) and is returned as a NumPy array with a complex dtype representing the attributes after the filter.

I suggest making the following name changes:
```suggestion
        filtered_shader_attributes = filter_attributes(
            self.attributes, shader_attribute_names
        )
```

        copy.model_matrix = self.model_matrix.copy()
