Cool Video on the Merits of HDRI for 3D Rendering

The images you use as sources and output have a big impact on the realism of your renders. This video from dimensiont on YouTube looks at the value of using HDRI images when doing renderings. I think the video could use a different soundtrack, but the examples given are convincing.

In the video, you’ll see the difference in colors, shadows, lighting and reflections between high dynamic range images and formats like jpeg and png. The video does a great job of making the difference in contrast and detail obvious. It also gives you some hints to the value for different lighting environments though I’d say the video could use more lighting examples.

Watch this video if you’re working on placing made objects and people into real-world environments or struggling to fine-tune a render.

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
