How to Use FluidRay RT Post Processing for Fast Render Tweaks

Introductory tutorial on how to setup a basic real-time image post-processing in FluidRay RT.

Rendering complex scenes can take some time. Post-processing in FluidRay RT lets you keep refining renders without starting over and see the changes in real-time. This video will cover:

  • Extracting the different output images from a rendering
  • Visualizing the output images in the Render View
  • Changing the color and intensity in real-time
  • Applying Reinhard Tone Mapping to adjust appearance
  • Automatically saving the output images at specific intervals

How to Use FluidRay RT Instancer Nodes to Render Highly Complex Scenes

FluidRay RT Tutorial on how to create scenes with thousands of objects without using much memory, such as a forest.

Complex models, such as trees and grass, can use huge amounts of memory. Instancer nodes allow to re-use the same models in different location of your scene, allowing you to create renderings with thousand of complex objects without much memory consumption. This video will cover:

  • Creating the Instancer node in the Graph Editor
  • Assigning trees to the Instancer node
  • Making the Instancer node duplicate the trees all over the scene
  • Making the duplicated trees stick on the terrain

How to Use Node Containers in FluidRay RT to Organize Your Scene

FluidRay RT Tutorial on how to organize your scene using container nodes.

When rendering complex scenes, the number of materials and objects can become very large. In FluidRay RT you can organize your assent into containers to make your project easy to manage. Containers can also be used to add multiple nodes all at once into the asset library. This video will cover:

  • Creating new container nodes in the Graph Editor
  • Entering and exiting container nodes
  • Adding and removing nodes from containers using drag & drop

How to Use FluidRay RT Volumetrics for Fast Fog Rendering

FluidRay RT tutorial on how to add real-time participating media to a scene, supporting multiple scatterings.

Volumetric effects, such as fog, god rays and clouds can add great realism to a scene.
FluidRay RT supports rendering homogeneous (i.e. the density is constant in the medium, such as fog) and heterogeneous media (i.e. the density varies in the medium, such as clouds). This video will cover:

  • Adding a homogeneous medium to the scene
  • Adding an object containing a homogeneous medium using drag & drop
  • Change medium parameters

How to Use FluidRay RT Ambient Occlusion for Fast Preview Rendering

FluidRay RT tutorial on how to render ambient occlusion in real-time.

Ambient occlusion is used to quickly generate a preview of scenes by approximating the light reaching each shaded point, based on how much the point is “occluded” by the surrounding geometry. This video will cover:

  • Using the Occlusion Integrator to render Ambient Occlusion
  • Tweak Ambient Occlusion Paramenters

How to Add Multiple Light Outputs to FluidRay RT for Faster Post Processing

FluidRay RT tutorial showing how to generate separate outputs from multiple lights at the same time.

Sometimes, for example in interior renderings, it’s useful to render the same scene with different lighting configurations.
In FluidRay RT it’s possible to generate a different image for each light in the scene at the same time, and then mix the images later. This allows to render the scene only once, and then in real-time tweak colors and intensity of each different light and not having to wait to re-render the scene. This video will cover:

  • Make each light generate a different output image
  • Visualize the different outputs in the render view

How to Use Normal Mapping to Add Surface Detail to Materials

FluidRay RT tutorial on how to apply surface perturbation in real-time using normal mapping.

Real surfaces are almost never perfectly flat, but present small variation on the surface orientation. To add small scale surface detail, normal maps can be used. This video will cover:

  • Import a normal map image into FluidRay RT
  • Apply Normal Mapping to an existing material
  • Change the amount of surface detail

How to Mix Complex Materials for Photo-Realistic Renderings

FluidRay RT Tutorial on how to mix the scattering properties of different materials, based on a texture.

In real-life, materials change scattering properties depending on the point on the surface. In FluidRay RT you can mix different scattering properties and select between them based on a texture. This video will cover:

  • Use the “Mix Scattering” node to mix different scattering types
  • Use a checker texture to select between them over the surface

How to Edit FluidRay RT Materials for Complex Transparency

FluidRay RT Tutorial on how to use an alpha mask texture to make an arbitrary material (in this case metallic paint) transparent in certain areas.

To create a highly detailed scene, sometimes it is necessary to make a particular material transparent in certain areas, to obtain effects such as holes or wear due to rust. In FluidRay RT you can create arbitrary complex transparent materials using a combination of “Mix Scattering”, “Null Scattering” and a texture mask. This video will cover:

  • Use the Material Testbench to create custom materials
  • Use a combination of “Mix Scattering”, “Null Scattering” and a texture mask to achieve transparency

How to Edit FluidRay RT Material Scattering for Real-Life Look

FluidRay RT tutorial on how to change material appearance by changing the scattering properties.

In real-life, one of the biggest difference between materials is how they scatter light in all directions. A diffuse surface scatters the incoming light uniformly in all directions, a glossy surface scatters incoming light in only a small cone of directions, and a perfectly specular surface (such as a mirror) scatters incoming light in only one direction. Every material in FluidRay RT can choose from a large set of scattering types. This video will cover:

  • Change material scattering types
  • Apply a texture image to the scattering type to make the color change over the surface
