The light window is not working for me

[ScienceAnimator]

Has anybody had trouble with the light window?

I have created a cube on a 3D layer and I am trying to change the light source. When I open the light window, all the settings are grayed out as if I'm not on a 3D layer. It doesn't seem to matter what frame I'm on (frame zero or other). I can't figure out what I'm doing wrong...

I am using Moho Pro Version 13.0.2 build 610.

Do you mean you converted a vector layer to 3D?

As far as I know - the light feature will only work with imported 3D objects (.OBJ's).

Ahh, thank you SimplSam.
I imported a 3D object from Custom Content and the light window works on this layer.
