model itself. Let’s take a look at something

very basic you see every day: a glass of

water. Nothing special at a first glance,

but it can be really tricky to achieve that

convincing render. No matter what render

engine you use to create an image, or

which software you model the parts in, the

rules are the same.

Rendering realistic-looking
liquids is not as easy as it
seems. Have you ever been in a situation
where you have spent precious time
creating a model with the intention for it
to imitate liquid, but there was something
strangely off about it? There are a few
possible causes: the environment and
lighting settings, incorrect Index of

We will begin with the modelling stage,

as it is crucial. Even if the model looks

good it has to be properly designed, or

no materials and lighting will help it to

look convincing. Of course, you can use a

software of your own preference and the

techniques may differ, but it is the final

result that matters. For the purpose of this

tutorial, let’s open ZBrush and get started.

most 3d software share the

same IOR values, but some

can vary ever so slightly
