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

/in ,

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

/in

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

/in

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

/in

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

/in

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
