When testing out a new render engine (or any tool that can do rendering), one of the typical objects I try to get a decent image of is a quartz crystal. In order to get that right, a rendering needs to contain effects such as dispersion, proper refractions and SSS. In this tutorial I’ll walk you through my first attempt to render a Quartz in Mantra in H16.
