I've been trying out realtraffic, and specifically an FBX export of my baked/recorded setup out of C4D. The traffic lights are driven towards a visibility tag. Can this be configured to something else? My issue is that I can't export baked visibility animation keyframes using FBX.
Could one imagine to drive the traffic light with another value, for example object scale, or a light switch, even just a boolean value in xpresso? Or is there another way of solving this?

The traffic lights (and also the brake lights and indicators on vehicles) are not necessarily be controlled by Display tags. You can also assign a light object, in this case the brightness is controlled. The simpliest option is switching the lights by the render visibility and/or editor visibility. Certainly this makes fading impossible since it's just a switcher (boolean).

I don't know, whether FBX can transport one of these alternatives.

Thanks for this. The only way for me to export this properly to Unity is using an animated scale value. To switch it on, I use a scale of 1, to switch it off, a value of 0. Then it's baked into the FBX animation tracks. There will be no fading. How can I drive the scale of an object (brake light for example) through the realtraffic "brake light" component then? Thanks!
