I'm curious if there is a way to do this. Or a script that might be available?

Convert: possibly export the project to an XML file...
1) Reduce project to only the minimum data needed, I.E. 1 comp with nulls to be converted to lights only. Nothing else.
2) Export project to XML "nullsproject.xml"
3) Make dummy project with 1 comp containing the type of light you want to replace the nulls with.
4) Export dummy project to XML "lightsproject.xml"
5) Open "lightsproject.xml" in a text editor, find the parameters for the light...
6) Open "nullsproject.xml" in a text editor, find the parameters of the null...
7) Find & replace the values in "nullsproject.xml" with relevant parameters of "lightsproject.xml" where appropriate.
8) Save "nullsproject.xml" as "nullsprojectconverted.xml"
9) Import "nullsprojectconverted.xml" in to AE.

I have no idea whether this will work practically or not. I'd suggest doing a small test with 1 null and 1 light to try it out, then scale up.

Of course you can easily parent a light to a null, and you can also use expressions to link the transform properties.

Best of luck - let us know your results!

Just tried that... You're going to need a magic decoder ring. So little human-readable data in even the simplest of AE files that I do not envy your task.

Where is the null data coming from? Why do you need to convert them? More info might help your cause.

I might be over simplifying this... but why not just make a new light for each null and then make each of those lights a child of each null and zero out the position? Once the lights are in place you could just adjust the intensities...

Sweet christ my head hurts... let Cinema do the work.
If you want Lights in AE make lights in C4D.

Export the Comp from C4D to AE (be sure to enable "Include 3D Data")

Thankyou Mylenium! That's exactly what I was looking for and that script was designed to solve the exact issue I was dealing with. I was using Cameratracker to track shots and then create null objects based on the tracking points. I wanted to use those points with Plexus but Plexus doesn't use nulls. It uses lights. Cameratracker can't make lights from tracking data. See the dilema? Thanks for the help guys!
