Draw beam option not available in lighting instruments

[thesilentowl]

I was sent the drafting for a theatre (so I didn't build the file) and I am adding in the lights now, but the "draw beam" option button is not available in the object info pallet.

 

I opened a new file, confirmed that the option is there when I drop in a light. And then went back to the original file and attached the record from the clear file to the lighting symbol, but the lights still do not have the draw beam option. I am not sure what else I can do to trouble shoot this so suggestions would be great.

check the spotlight preferences and available parameters. Also, lights must be assigned to a focus point.

If it’s just greyed out, make sure the lighting device is turned on (right click, OIP settings, or visualization palette). May even need to focus it. Also check your spotlight classing for beam / field angles and centerline while you’re in spotlight preferences.

I assigned a focus point. The option is not there at all.

It sounds like someone has customized the OIP.
The control should always be there just disabled when the proper conditions do not exist.

Since the option is not shown at all go into Spotlight Preferences, on the Lighting Device: Parameters tab, in the Settings Popup select <Spotlight> then click OK.
The parameter should then show.

That was it! Thank you so much. I didn't know that was a feature.
