In the 4.19 release and according to the Live Link Plugin document page there should be a plugin for MotionBuilder:
But I can’t find the plugin for MotionBuilder. Has anyone been able to find this? I assumed it would be in the extras folder with the maya live link plugin.
nav to the engine istall location and Engine\Extras\MayaLiveLink
Unzip it (would recommend doing it to another folder)
Copy to your version of maya, the install folder, and put it in the plugins folder (if you have maya open will need to turn if off for it to detect the plugin)
enable the plugin in maya
to do so, in maya
windows(from the top bar)
settings/preferences
plugin manager
and find the live like plugin in there,
if you don’t see it you will need to browse for it, as it don’t always auto detect it
then after that, hit auto-load and loaded (as if it don’t autoload the next time, might have to do it once or twice, which is a maya thing)
You will see it kick in at the mel scrip console line.
then in UE4 ->menu bar-> window->live link
add → message bus source -? maya live link
and the live link on maya should turn green
Now your playing with fire.
well they talk about it here being (as from the doc), download and in the engine files some where.
