NextTut shows how to use Arnolds’ physical capabilities to create an in-render Chromatic Aberration effect.
This new tutorial from NextTut shows a neat way to create a Chromatic Aberration effect with Arnold Render. There are ways to get lens effects using Imagers in Arnold as post-rendering effects and, of course, through compositing techniques. NextTut shows that an easy (but probably not the most efficient) way to get that classic red/green fringing is to use Arnold’s physical properties to make it happen in-render.
The technique involves placing a lens shape before the render camera. The results are physically accurate and work well, albeit with a hit on render times.
