Light symbols completely dark when rendering

Hi there

 

Is there an easy way to make the lens of a light symbol glow when emitting light? My renders are looking a little odd - when the lights are lighting objects and people correctly - but you cant see light coming out of them. Ive tried muliple render modes - but to no avail.

 

Cheers

Not necessarily easy, but it can be done.

 

The SLD must have a lens object grouped with the body. The Light Info Record must be attached to the group, Sometimes that means un-attaching, editing and reattaching.

 

You'll need a glow texture set to object attributes, and a class for the lens object with the texture assigned in the class. In File>Document Spotlight>Spotlight Preferences look at

 

Lighting Instrument Color set by

check Color Field

and color field for Pen and Fill

 

Then Modify the geometry in you lens class.

 

Once you set upon a template file and modify your symbols it whoppers by default. The SLD symbol in the libraries pretty much all have lens object grouped wit the body. Other symbols may require the lenses to be modeled.

Hello symo:

 

One way is to use a texture that is set to Backlit for Reflectivity, and that is also set to not Cast Shadows.  It should also have the Indirect Lighting turned off in the texture so that it doesn't add extra light to the scene.  This allows the lens to glow when the light behind it is turned on.

 

Another way is to use Glow Rfelectivity, but that has to be controlled by class and it not affected by the light object On/Off, so that can be less convenient than using Backlit which will automatically glow when the light object is on.
