Multiple lights modification

Sometimes you need to make the same property modification for many of the lights of the project.
You can do it thanks to the Multiple Modification command specifically dedicated to lights.

Command name is Lights->Multiple edit; it is available in Layout window, in the Virtual 3D section of the Ribbon, Lights group. Once you have selected the command, select all the lights you want to modify by drawing a region that contains them with the left mouse button.

You will notice that selected lights will be highlighted with a blue based colour; a property mask will appear, where you can start modifying lights common properties (see following image).

As you can see, common properties you can edit within this mask are:

• Switch light on and off
• Change light elevation. You can modify light source elevation, as well as target in case of a spot light
• Rendering effects: you can set a different value for light multiplier and photometric light intensity
• Move/copy: in this section you can move selected lights specifying the Delta (which is the distance from the old and the new position) for the movement. Delta X is the horizontal offset (if positive light moves to the right side of the screen, if negative to the left); Delta Y is the vertical one (if positive light moves to the top, if negative to the bottom side of the screen). You also can duplicate selected lights (copy), specifyin the offset between the source and the copy

Note that properties will be applied to all selected lights
