It is clear the difference this form of lighting can make to rendered images. And the enormous advantage
here is that it is much easier to set up than traditional lighting.
Image-based Lighting Setup
1. On the Lighting Tab, click on the Recommended folder in the left hand side of the palette.
2. Drag the Environment Light Studio into the palette on the right. This replaces all lights that were in
the palette with an Ambient and an Environment light containing our High Dynamic Range Image.
3. Click on Render to render the scene using the default image contained in this Environment light. This
type of render can take slightly longer than traditional lighting methods, but the results are worth the
extra time invested.
4. To use an alternative sample image, click on the Environment folder on the left to show another two
example environment lights; a Sky (used in the example above) and a City. Drag the City light over to
the right to replace the Environment light in the palette (which should be deleted before rendering).
5. To manually insert a new HDRI, double click on the Environment icon in the palette, select the Edit...
button next to Environment, click on the "..." button next to Filename, and browse to the .hdr file
required. For this to work correctly, this HDRI must be a Light Probe HDRI. (Additional Light Probe
HDRIs are available from a variety of places on the Internet, including Dosch Design.) Click on OK in
both dialogs to set the new image to be the light source, and click Render to produce a newly lit
rendered scene.
