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 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

Starting FluidRay RT from command line

With the latest version of FluidRay RT it’s possible to import files directly from the command line.

First of all, you need to find the installation location of the executable file fluidrayrt.exe.

For example, it could be in C:\Program Files\FluidInteractive\FluidRay RT Demo x64\fluidrayrt.exe.

You could then import a file from command line by calling C:\Program Files\FluidInteractive\FluidRay RT Demo x64\fluidrayrt.exe -i <file to import>.

Of course, by adding the path C:\Program Files\FluidInteractive\FluidRay RT Demo x64\ to the system PATH environment variable, you would just have to call fluidrayrt -i <file to import>.
