When we observe materials in real life, transparent materials like glass can vary in color depending on the thickness of that material. Window glass, for example, will show very little color in areas where the material is thin. However, when...

When you set out to create a realistic rendering, referencing real life objects, environments and lighting is a great way to ensure your results are accurate. One naturally occurring phenomenon to be aware of is caustics: concentrated light rays...

Let's talk about perspective. Any image rendered with perspective enabled will show convergence, or vanishing points, for all parallel lines. In most cases that is desired since perspective helps us understand scale and proportion, and it’s a...

Material Samples (sometimes called glossy samples) control the amount of information a material collects from neighboring objects or the surrounding environment. Most materials in the KeyShot library include a default sample value for that...

Metals draw most of their color from the objects around them, which can make them challenging to photograph or render. These materials, such as chrome or stainless steel, are primarily driven by their reflections. We describe metal colors using...
