Displaying light objects in Open GL

Recommended Posts

I have created an site model of a long driveway with lighting columns as symbols spaced along it, but when I view in open GL, only 2 of the lights are fully on 'on' at a time, with a third showing reduced lighting... All of the symbols are the same and the light objects within are switched on. To Make a different light 'come on' I have to increase the brightness slightly, but then another light goes off somewhere else.... I enclose a couple of screenshots to demonstrate. There is also a heliodon object but this is turned down so you can see the layout and the light spread better.

Is this a setting or a limitation of my graphics? Thanks in advance.

Hi Lee


In OpenGL, there is a limit of (I think) 8 lights. (But it could be 10...) 

If you render with Fast Renderworks, you should see all the lights in action. So, when you get your model displayed in some Viewports, you'll be able to see all the lights, and also be able to control them from the Visualization palette.


Hope that helps.
