How to Use Redshift for Production: Tips and Tricks from Proteus VFX
How Proteus VFX Used Redshift to Create Stunning Visual Effects in Production
Redshift is a powerful GPU-based rendering engine that can produce photorealistic images and animations in a fraction of the time compared to CPU-based renderers. In this article, we will explore how Proteus VFX, a leading visual effects studio, used Redshift to create amazing visual effects for various projects, such as movies, commercials, and TV shows.

What is Redshift and Why Use It?
Redshift is a biased renderer that uses ray tracing and global illumination techniques to simulate realistic lighting and shading effects. Unlike unbiased renderers that try to simulate every possible light ray in a scene, biased renderers use approximations and optimizations to speed up the rendering process while still achieving high-quality results.
Redshift is designed to take advantage of the parallel processing power of modern GPUs, which can handle thousands of calculations simultaneously. This means that Redshift can render complex scenes with millions of polygons, hundreds of lights, and dozens of shaders much faster than CPU-based renderers. Redshift also supports out-of-core rendering, which means that it can use the system memory and disk space to handle scenes that are larger than the GPU memory.
Some of the features that make Redshift stand out among other renderers are:
Adaptive sampling: Redshift automatically adjusts the number of samples per pixel based on the noise level and complexity of the scene, resulting in faster and cleaner renders.
Unified sampling: Redshift uses a single sampling algorithm for all types of effects, such as anti-aliasing, motion blur, depth of field, shadows, reflections, refractions, etc. This simplifies the workflow and reduces the need for tweaking multiple settings.
Physically based materials: Redshift supports a wide range of realistic materials, such as metals, plastics, glass, wood, skin, hair, cloth, etc. These materials are based on physical properties and can be easily customized using textures and masks.
Sub-surface scattering: Redshift can simulate the light scattering effect that occurs when light passes through translucent or semi-transparent objects, such as skin, wax, marble, etc. This adds more realism and depth to the renders.
Volumetric rendering: Redshift can render volumetric effects such as smoke, fog, clouds, fire, etc. using OpenVDB data or native 3D grids. Redshift also supports volumetric lighting and scattering effects.
Nested dielectrics: Redshift can handle complex scenarios where multiple transparent objects are overlapping or nested inside each other, such as ice cubes in a glass of water or bubbles in a soap foam. Redshift automatically calculates the correct refraction and reflection effects without artifacts or errors.
Material blending: Redshift can blend multiple materials together using different modes and masks, creating complex and layered surfaces such as rusted metal, wet sand, snow-covered rocks, etc.
AOVs: Redshift can output various types of render passes or AOVs (Arbitrary Output Variables) that can be used for compositing and post-processing. These include beauty, diffuse, specular, reflection, refraction, emission, depth, normal, motion vector

Redshift allows them to render complex scenes with high-quality lighting and shading effects in minutes or even seconds, without compromising on the details or accuracy.
Look Development
Proteus VFX uses Redshift to create photorealistic materials and shaders for their assets and characters. They use Redshift's physically based materials and material blending features to create realistic and layered surfaces, such as metals, skin, hair, cloth, etc. They also use Redshift's sub-surface scattering and nested dielectrics features to simulate the light scattering and refraction effects that occur in natural materials. Redshift's node-based shader graph allows them to easily customize and tweak their shaders according to their needs.
Rendering
Proteus VFX uses Redshift to render their final images and animations for their projects. They use Redshift's adaptive sampling and unified sampling features to optimize their rendering settings and reduce the noise and render times. They also use Redshift's volumetric rendering and AOVs features to create stunning atmospheric and environmental effects, such as smoke, fog, fire, etc. and output various render passes for compositing and post-processing. Redshift's out-of-core rendering feature allows them to handle scenes that are larger than the GPU memory without crashing or slowing down.
