To set up image-based lighting
1 Open the Presenter window, and click the Lighting tab.
2 Expand the Recommended archive in the left pane of the Lighting tab.
3 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 a
High Dynamic Range Image.
4 Click 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.
5 To use an alternative sample image, expand the Environment folder in the left pane to view another two
example environment lights; Sky and City. Drag the City light into the palette on the right to replace the
Environment light in the palette.
NOTE Before rendering, either delete the Environment light from the palette, or deselect the check box.
To manually insert a new HDRI
1 Open the Presenter window, and click the Lighting tab.
2 Right-click the Environment light in the palette on the right, and click Edit on the shortcut menu.
3 In the Light Editor, click Edit in the Environment field.
4 In the Shader Editor, click the Browse button (...) in the File Name field, and browse to the required HDR
file.
NOTE 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 dialog boxes to set the new image to be the light source.
5 In the Presenter window, click Render to produce a newly lit rendered scene.
Use Presenter RPCs
RPC Tab
The RPC (Rich Photorealistic Content) support in the Presenter window enables the addition of photographic
scenery to any 3D project. RPC files can be bought directly from ArchVision, and typically come in libraries of
content ranging from trees and plants to people. They also come in a variety of types.
■ 2D RPCs are single-direction 2D photographs that always face the camera, and are a single frame, looking
the same from every angle, and not animating.
■ 3D RPCs are objects that have a high number of frames allowing the camera to move around the object and
see it from all angles.
■ 2.5D RPCs are animated, single-direction 2D photographs. Animated RPCs will only animate visually when
exported as a rendered animation.
■ 3.5D RPCs include animation and views from all around the object.
■ 3D+ RPCs, often called smart content, are not currently supported.
