Light Tags

You can use the Colorway Kit to add Colorway light tags to lights in C4D. When the file is exported and opened in Colorway, the tagged lights are selectable for editing in Colorway.

Tagging a Light

You can add a Colorway Light tag to a light in your C4D project by doing the following:

1.   Select the light you want to tag in the left column of the Projects panel.

2.   Select the Tags tab in the Projects panel by clicking on it.
3.   Select ColorwayKit Tags > Colorway Light.

This displays a small Colorway icon next to the light showing that it has been tagged. The tagged light is then selectable in Colorway when the project is imported.

Light Parameters and Options

When you add a Colorway light tag to a light in C4D, you are presented with some parameters. To view the parameters, select the tagged light in the Projects panel; the parameters are displayed beneath the Projects panel. Ensure the Colorway Light tab is selected.

Group Option

You can use an optional group name for light tags when exporting your project to Colorway. If this is left blank, the name of the object that the tag is assigned to, is used.

To add a light tag to a group, in the Group text field, enter a name for the group. Light tags with the same group , which was either entered manually, or derived from the object name, form a single, editable light in Colorway.

Note:  If you want to be able to edit an individual light in Colorway, ensure the light tag has a unique name or group so it remains as an individual light. For instance, if you have a light called table lamp with no group set on the tag, and you have set the group on several other light tags to be table lamp, they are grouped together because the final group for all those lights is table lamp. This is due to the fact that the first light uses its name, as no group is set on the tag.

Hide Objects When Off

When a light is disabled in Colorway, you can select the Hide Objects When Off checkbox to turn the Render Mode of the luminous object off. This hides the light’s geometry.

Normally, when luminous objects are rendered as lights, turning the light off simply disables the Luminance channel of the relevant materials. This is to allow the object to remain visible in the scene. This is useful when rendering strip-lights, for example, where the camera visibility of the ‘tube’ is an important part of the rendered image. Sometimes, you don’t want to see the actual geometry when a light is muted, as the geometry produces unwanted shadows in global illumination.

Note:  This option applies to all objects affected by the specific tag it is set on. If you have two sets of objects with light tags in different parts of your scene, but with the same group name, you can independently set this option for each tag, and the render behaves as expected.

Select Objects

Clicking Select Objects, selects all the objects that are part of the light group that the tag relates to.
