I have a simple object which I am repeating in an array. Then I am applying a subdivision surface modifier at the end of that stack. I would have thought that the array modifier would have merged points where there is some overlap (like the mirror modifier) and so that if I applied the subdivision modifier after that it would be smooth. But instead I am getting the subdivision effect applied to where the individual segments of the model are repeated in the array. Does anyone know how to get around that? Or do I have to apply the array and merge verticies to make it work?
Here is what I mean: (you can see that I have temporarily added some supporting geo to make these indented ridges less of an issue, but eventually that will not work because there will always be some rounding).
