Lighting and shadows do not carry over from SketchUp. Lights can be added in Inspector, in the Vizard script, or both. By default a head light is enabled that illuminates whatever is in front of the viewpoint. Directional, Spot, and Point Lights can be added and positioned anywhere in the scene. Additional processing power is required for each light added to the scene and there is a limit of 8 custom lights (7 if the head light is enabled). Lighting calculations are different depending on whether 'Effects' are enabled or disabled.

Custom Lights
Custom Lights
Custom lights are added through the Create > Light menu. Go ahead and add a directional light. Next enable translate or rotate mode to set the light's position and orientation. The position of a directional light does not affect its output, but can be used to move the node's icon to a more convenient location for visualizing it in Inspector:
