Scene Transition

[GWD]

Where can I find the Scene Transitions setting in Ruby?

Try
Sketchup.active_model.options["PageOptions"]["TransitionTime"]
and
Sketchup.active_model.options["PageOptions"]["ShowTransition"]
returns the values - say 1.0 and true.
You can rest them thus:
Sketchup.active_model.options["PageOptions"]["TransitionTime"]=0.0
or
Sketchup.active_model.options["PageOptions"]["ShowTransition"]=false
