How to Create Realistic Interior Lighting with FluidRay

We are in trying times. No matter each of our specific situations, everyone has been affected by the global pandemic and we’ve all had to modify our day to day lives in order to keep our communities safe. The FluidRay team wishes everyone the best as we all adjust. 

Are you able to work remotely? Why not use this time to refine your rendering skills with these tips on how to use FluidRay to create renderings with realistic lighting? 

Proper interior lighting is crucial when designing an interior, particularly when working to create the ambiance of a room. Lighting adds both style and function and determines the mood of the space. Perfecting the lighting effects in 3D renderings enables designers to accurately communicate the intended mood for a room. Creating lighting effects in FluidRay is fast, easy, and produces beautiful results that will impress your clients! 

Keep reading for detailed instructions on how to bring your renderings to life with interior lighting. 

Step 1: Import Your 3D Model

Create your 3D model in your favorite modeling software. We used SketchUp for this example.

SketchUp 3D Model

livingroom.skp

Once your model is created, import the file into FluidRay. 

FluidRay Import Project

FluidRay works directly with SketchUp (.skp), Rhino OpenNurbs (.3dm), FBX (.fbx), Alias Wavefront (.obj), Collada (.dae), 3DS (.3ds, .ase), DirectX (.X), Stanford PLY (.ply), and STereoLithography (.stl). 

If your filetype isn’t listed here, simply export to an .fbx file within your 3D modeling software and then import into FluidRay. 

Step 2: Set Materials

Let’s begin by setting the materials in the model. By setting materials before adjusting the lighting, you can see how the materials will react in real time when adjusting the lighting. Select an object from the model and then from the drop down menu in the Materials tab, drag and drop the desired material into your rendering. FluidRay has a large library of high quality materials from which to choose and the ability to import additional materials. 

Step 3: Add Environmental Light

Environmental light comes from the outside, rather than from the inside. Environmental light is a global parameter, meaning it will affect the entire rendering, not only one part of it. 

FluidRay Drag and Drop

In this example, we start with the night environment and then we increase the light’s power.

You can see the room in our model takes on light from the environment as if it is night time outside. Increase the light’s power in the right panel using the Environment tab.

Step 4: Add Artificial Light

FluidRay

Artificial light includes overhead lights as well as table or floor lamps. We recommend applying the artificial light first without the environmental lights. Simply select the surface you want to emit light and tweak its emission power and color. You can also drag and drop an emissive material onto the surface.

Go through these same steps for each of the artificial lights in your rendering. 

Step 5: Turn Environmental Light Back On

Turn the environmental light back on so the rendering includes both environmental and artificial lighting. This rendering is really coming together!

Step 6: Finalize and Adjust Your Rendering

In this final step, you’ll tweak the materials, environmental lighting, and artificial lighting to get to the final result. Thanks to FluidRay’s speed and ability to render in real time, you’ll immediately get an idea of how the render will look after each and every material or light change.

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.

Merits of HDRI in 3D Rendering

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
