Deep Dive into Refractive Objects - Introduction
 

One of the hardest materials to render physically accurate and in reasonable amounts of time are Refractive materials like Water and Glass, and it gets even harder when many of these materials interact with each other. For example a Glass filled with wine, ice and some bubbles.
In this series we will dive deep into the underlying concepts of Nested Dielectrics and see how to setup our models and materials for the best possible outcome.
Most of the information in this series applies to Cinema 4D’s Classic Renderers (Standard and Physical), and also Redshift.
Amongst other things, I will show you some frequent mistakes users do when setting up Refractive Objects, the importance of modeling and polygon normals, Index Of Refraction (IOR), and how a ray travels through multiple mediums.

Deep Dive into Refractive Objects - How does Cinema 4D Calculate Refractions
 

In order for the Renderer to calculate the indexes of refraction for dielectric objects correctly, it needs to know exactly when a ray enters a medium and when it exits.
In this video I will show you how a ray travels through many refractive mediums and how it calculates each refraction by using a method called “Nested Dielectrics”.

Deep Dive into Refractive Objects - Common Errors when Using Refractive Materials
 

When setting up scenes with Refractive Objects, I have observed over the years, a number of errors that happen frequently. These are:
The Single Sided Glass Problem, that causes thin glass objects to act as a thick lens rather than thin glass, mainly from the lack of model thickness.
Also, inverted polygon normals cause inaccurate renders and artifacts on most renderers, and although Standard and Physical are quite tolerant, Redshift, and all other modern renderers are NOT.
Another frequent issue is caused by the assumption that in order to create cavities in objects, for example bubbles in ice or water, you need to reverse the normals of the bubbles and connect the outer model with the inner one. This may work in some circumstances, but will fail when the composite object is inside another medium. (Ice with bubbles is inside water).
Finally, refractive objects that are touching another, non refractive solid object, should NOT have any overlaps, and rather have a small gap between them.
In this video I will go through these scenarios in detail and explain how to avoid them.

Deep Dive into Refractive Objects - Setting up Objects for Correct Refractions
 

In order to make your refractive objects interact properly, so that the “Nested Dielectric” principle applies correctly, you need to make sure your models overlap by a very small amount where the two mediums touch.
In this video I will demonstrate what happens if they don’t, and then I will show you how to model a simple wineglass filled with wine, with an ice cube in the wine, and some bubbles. In the process, we will apply all the techniques discussed in this series.
I will also explain how Ray “Trace Depth” can hugely affect render quality.

Learning Cinema 4D’s Tools & Objects: Drawing a Wine Glass Basic shape
 

Using the Spline Pen Tool, and various commands, we will draw the profile of a wine glass to use with a Lathe Generator, in order to create a wine glass model. In the process, we will learn how to create and modify spline points, align them, as well as how to add thickness to splines to create uniform thin glass surfaces, like the main body of the wine glass.

Learning Cinema 4D’s Tools & Objects: Adding Details to the Wine Glass
 

In this video we will take the basic profile we created in the previous chapter, and add some fine ornamental details and rounding to all corners. We will also make sure the polygon orientation (normals) are pointing in the correct direction, so that we don’t have issues when rendering.

CG Event Rewind: A Glitch in the Metaverse with Red Giant | Chad Perkins
 

In this session, Maxon Senior Trainer Chad Perkins will create a 3D metaverse scene in After Effects by sending camera tracking data from After Effects to Cinema, bringing in a 3D character from Cinema 4D, turning it into a hologram, reflecting all of that into a live action plate, and compositing it all together. In the process, he’ll look at multiple ways to create 3D objects using Cineware and Trapcode Form, he’ll create disruptions in those particles using a clip from a vintage martial arts movie (Ninja Death III, if you’re curious), quickly create scrolling lines of code using plugins from Red Giant Universe, create and track a procedural reflection using tools from the VFX Suite, and composite it all together using Supercomp.

All About Iterators: 01 - Course Introduction
 

In this artist-friendly series we’re going to explore one of Cinema 4D’s biggest productivity boosting toolkits: iterators.

Even if you’ve never heard the word before, this in-depth course will open up new ways of working and thinking, enabling you to completely automate repetitive tasks and solve problems you thought only programmers could tackle.

All About Iterators: 02: - Building Our First Iterator
 

Artists are often scared to even think about using Xpresso. So in this video we’re going to build our first little iteration machine from absolute first principles - no knowledge required.

All About Iterators: 03: - Client Logo Project (Object Lists)
 

In this chapter we’ll start to solve real-world problems with iterators. Using the practical example of a client logo we’ll learn how to automate control of over twenty sweep objects in a fun and intuitive way. This will enable us to experiment and play with a form that would otherwise be quite painful to work with!

 
David Todman Dec 15 2021 12:30 407
All About Iterators: 04: - Client Logo Project - Range Mapping
 

The term “range mapping” might sound technical or intimidating. But this video contains a beginner’s guide to exactly what a ranger mapper does and how its interface can be used to create flowing, tweakable controls. That’s actually quite creative.

 
David Todman Dec 15 2021 09:06 279
All About Iterators: 05: - Client Logo Project - Reference Node
 

Taking our new skills to the next level, here we’ll learn about a new node, a new language and ways to build our own custom interfaces for controlling many objects at once.

 
David Todman Dec 15 2021 17:33 252
All About Iterators: 06: - Paper Loop Project - Hierarchy Lists
 

Another project based chapter providing the opportunity to elevate our skills even higher. This chapter looks at an animating paper loop where we start with a hand drawn sketch and too little information from the client! By using yet more iteration nodes we’ll learn how to control multiple objects in ways that will adapt to changing information and geometry as we go along. This is great for reducing work-related stress and major mistakes under pressure.

All About Iterators: 07: - Paper Loop Project - Auto Spline Distribution
 

Distributing items along a path is quite a common / boring task. In this video we’ll learn how to use iterators to completely automate the process in a flexible and adaptable way.

 
David Todman Dec 15 2021 08:08 226
All About Iterators: 08: - Paper Loop Project - False Perspective
 

In this video we’ll learn a neat trick for recreating the false perspective of an initial client sketch using yet more iterators.
