Couldn`t get them to export no way I tried.
I am curious what you might need them for in the "other" application that a workaround you can replace once exported won`t do?
CHeers, Klaus
edit: in the tgd I renamed the class "spotlight" to "sunlight". The picture shows the errors and warnings window
when reopening the modified tgd. I guess it is simply not implemented.
edit: when I import a fbx from SI into TG the spotlights from SI are converted to "directional" or sunlights.
The parameters in the picture before are lost.
Might be something to finally ask for the TG SDK
