Hello,
I am having trouble changing the speed of the light streaks using paint in Motion 5.
I saw this video posted by Mark Spencer that demonstrated a solution to the problem.

It appears that the video was made with Motion 4.
According to the video, I'm supposed to go to Inspector->Shape->Stroke for the light streak, and select "Show in Keyframe Editor". But, in my Motion 5, it's grayed out. Does anyone know a solution to this?
