Maxwell for Rhino :: HDRI Tutorial

The Maxwell for Rhino plugin offers two ways to work with HDRIs (High Dynamic Range Images):

1. as environment maps used to light the scene

2. as Maxwell emitter materials, to be applied to geometry

HDRIs as scene Lighting

Maxwell is able to use HDRIs (.mxi, .hdr, and .exr) as the source of global illumination; this allows for very realistic environmental

backgrounds and optionally, reflection, refraction, and illumination. In fact, you can see in the Scene Manager’s Environment Settings

page, all of the settings which allow you to specify ‘Image Based’ lighting for separate Background, Illumination, Reflection, and

Refraction channels.

The HDRIs placed in these channels will be spherically mapped in such a way as to completely enclose the scene, and the plugin is able

to show you the effects of this in a Rhino (perspective projection) viewport. Changes to the channel’s Scale and Offset parameters are

also shown in the viewport, which makes it easy to set up your scene.

The fastest way to set up Image Based lighting in your scene is by right-clicking on one of the buttons in the plugin’s Environments

toolbar (if you don’t see this, go to Main Menu > Maxwell > Plugin Windows > Show All Toolbars):

When you right-click, for example, the Background channel’s button, you will be presented with a file dialog which has a preview

window for the various types of HDRI. Choose a file from your file system and click OK – now this image will be shown in the Rhino

viewport.

To adjust how this image is mapped, open the Scene Manager and go to Environment Settings. The plugin will have already switched

the scene’s environment Type to ‘Image Based’ as soon as you chose a valid map, so you can scroll to the Image Based section of the

window and expand the Background section:

1 2 ... 79 80 81 82 83 84 85 86 87 88 89 ... 100 101
