lights not working (but not all)

Recommended Posts

I think the geometry is for visibility in rendering.

Symbol is ok as being used multiple times.

So ok to include the Light Source - in VW - often Light Sources in Symbols/Instances

will not work in other software (e.g. VRAY4C4D).


If geometry is needed in a Symbol for calculations (?) - do something in.

If calculations work without anything else beside the Light Source,

leave it out if you do not need to see anything in renderings.

thanks, zoomer. i'm still disgusted that the light objects from the library don't provide the light 3d geometry.

i have to chew on what's been said in the thread.

I understand light fixtures like this :


A manufacturer, like Erco, creates a Symbol with the Geometry, Renderworks Textures, Class or Object Settings,

IFC and all other Data and finally includes a VW/RW Light Source with their IES Data.


At least I saw it that way for Chairs or Furniture (without lights of course)
