  • Adjusting the distance of lights to a surface.

Overview

Interactivity align one or more lights to a surface (polygons). This provides a fast way to manipulate lights in your scene,

  • Interactively set a light’s facing+position by clicking on- or click-dragging across- a surface.
  • Provides visual indication of where each light is pointed upon tool activation.
  • Control distance of light from surface.
  • Easily switch between selected lights; Max 50.

  • To move a light, left-click on a surface(polygon) or click-and-drag over a surface.
  • To alter the distance of the light from the surface, left-click on the blue arrow handle or right-click and haul the mouse forwards/backwards.

Please note,

  • After moving every 1-to-3 lights, shift-left-click in an empty area of the 3d view to apply the transforms. This will restore/improve interactive performance.
  • Initial handle placement is determined by hit testing against all geometry in the scene.
