► DESCRIPTION
How to Render Defined Caustics in Complex Scenes without problems using KeyShot. In this tutorial I'll walk you through the necessary steps to render clean and defined caustics. I'll start by establishing three prerequisites needed to generate caustics, before moving into KeyShot and setting up lighting presets, materials and lighting. After that I'll add a couple of more advanced materials to the ground, wall and spotlight and talk a look at the problems that arises. In the last section I'll show how you can use an additional model set, in collaboration with compositing in Photoshop, to overcome the issues.
