Try adding a Point3 XYZ controller to the uvwOffset node.

But what if we have multiple lights in the scene, each casting its own set of caustics? You would have to control the caustics effect globally (on/off) and additionally for each separate light, which gets really complicated.Good point. I guess having a check box in the LightSelect element to include caustics, in the same way that you can "Include Environment Light" would be one way to do it. That way the user can set up as simple or complicated as they want.
Currently you can enable the "Only in caustics element" checkbox and have beauty and caustics separately. Then you can composite them in post.Yep, this is what I do most of the time. However, if given the opportunity to do all my post work in the corona VFB then I will!
I mean a very thin layer of rainbowy film, when you see something really up close. I am just not sure if this effect appears on metals.I've noticed looking at many metal samples (mainly silver color) in the office that there is a layer that appears as a mix of green/purple at certain angles (unless it isn't an additional finish but just a characteristic of the specular reflection itself).
That micro specular color varies for other colored metals.
