View Full Version : Track light
2004-03-16, 02:59 AM
I created a track light with parametric length and number of spots. But I can't get it to Light UP when rendered. I tried creating the spot as an individual light fixture and nest it into the track, but they still don't light correctly.
Any input is appreciated

did anyone figure out why my track light does not light up right? :?

Lights up for me . :D
No sun, interior setting, both tracks on.

I have the same problem. I think Revit can't handle multiple light sources within a single family. If you look close at the renderings no matter how many heads are on the track only the first one created will be casting any light. You can even select all and copy and get the same results. (one light source in the project) The way I got around this was to create the family with only one head and a parameter to make the track length flexible, save this and load into a project, place a few instances and move them inline (flexing individual track lengths to achieve correct placement as needed) when everything is positioned correctly make it all a group and save it out as a group (file>save to library>save group) now you can load it into the project at hand and it will render with all heads having a light source and casting all the appropriate shadows. The downside is that you have to save a new group for every different arrangement and if you want to change the head style you have to create a new head family and a new track group before you can place it in a project. Unfortunately we can't attach .rvg files (revit group files) as examples on zoog, give me an email addy and I can send them if you wish.

TeamRPM is correct, revit cannot have several light sources in a single family. There are two work around that I use:
1. similar to rpm, i use a light source only family (no geomtery, similar to the studio light) and group it with the light fixture familiy in the project.
2. I use the linear lightsource template. This creates a more realistic lighting effect when shining the spots on the walls is not essential.

Thank you gentlemen. I will try the work arounds. I tried the linear light but like you said it still does not give the desired effect of individual spots.

use the grouping thing or zoog's post part 1
It will give you a fairly realistic effect. If you have trouble email me and I'll send you my base family and group.

Has anyone yet requested increased lighting control in accurender, yet. I know we've wanted it but its one of the wishlist items that I never remember to bring up.
