I tried using 3.7.94 to animate a robot walking. There's a big light on its head. The light should flash and turn dark so I used slot color to control its transparency. But the key icon turned orange while the autokey is on. when I move the timeline the color of the big light return to default.
Really don't know how to fix it... I tried delete its frame or change its name but change nothing.
There are lots of other animation so I can't just delete all and redo the work. Is there any way to fix this?
Thanks a lot if somebody help me!
