Learn how to render flicker free flythrough animations in V-Ray when using Irradiance map and Light cache as global illumination engines. In this tutorial we will explain how to correctly set up the GI engines in order to save and load a prerendered irradiance map and lightcache, to remove the dreadfull flickering in flythrough animations.
We'll cover all the settings for irradiance map and light cache while explaining every step in detail, so you'll get a good understanding of how these GI calculations work. This is very important to be able to set up GI in your own scene, as every scene will need slightly different settings.
This tutorial was created with V-ray version 3.0 . You will probably be able to follow along with older versions, but some screenshots may vary, or some settings may be missing or will have a slightly different effect on image quality.
The included max files are all created in 3D Studio Max 2013, but saved as 3D Studio Max 2010 files. So they will open fine in any Max version from 2010 up, but you will not be able to open them in older ones!
What will you learn?
Why do animations flicker?
By using a simple scene, we'll show you how Vray's Irradiance map works, how samples are placed, and how you can reuse saved maps to eliminate GI flickering.
Learn to use Irradiance map and Light cache to speed up GI calculations, and discover how to overcome all problems that these methods introduce in animations.
Prerender GI solutions
Each GI engine has its own way of saving and reusing their GI solutions. You'll learn about incremental saving, flythrough mode for lightcache, but also all settings that can have a dramatic impact on render times and how to correctly set things up for maximum quality.
Light cache theory
We'll cover the most important settings of the light cache rollout, as these are quite different compared to still image rendering, and they also vary based on your scene size and units.
The final goal of the tutorial is to provide you with a workflow that solves all flickering problems and results in a high quality animation while reducing render times.
What can you expect?
In depth information about global illumination, what causes the flickering, how to get rid of it and improve render times at the same time!
Detailed instructions that also explain the 'why' behind each setting. Don't just blindly copy some render settings, we'll make sure you also understand every parameter.
We first start with basic theory on a simple model, after which we apply the same workflow to a real interior flytrhough scene.
Screenshots for every step of the tutorial, so you can follow along with ease.
We provide step by step instructions, in an easy to follow, human language.
All 3dsMax scene files are included, in case you get lost somewhere along the way, or simply to study the scene setup and settings.
