Neon Sign
A neon sign is a sign that lights up when it has power. Its images, one for each frame, are the Frame URLs in the Signage panel.
The Neon Sign panel has one button, Preview image cycle. It shows the sign's frames one after another in the scene view, one each second, while the sign stays selected. Select something else to stop it. Only frames whose image is on the sign take part, so click Download and apply images in the Signage panel first.
A neon sign is an IO entity. Its first input lights the sign. In the game, power on its other inputs picks which frame the sign shows. Wire it in the IO Entity panel, see IO wiring.
Can edit several selected objects at once.
