okay i found the problem but cant get rid of it.
i used to have a 2d actor dummy for starting. now i changed it to a 3d full char.
in scenes where the actor has to talk, but hasnt to be visible ( mostly closeups) i simply moved my char out of the screen. ( actor.SkipTo (-200,0)
so he can talk but is not visible.
this doesnt seem to work for my 3dchar anymore. he just dont react on this call.
i think i will have to create an extra char for closeup scenes.
but why cant i move the char out of the screen like the old 2d one ??
