Just thought I would post this here for everyone benefit. If you've had a hard time getting vue renders to sync with lw renders when using the vue camera sync plugin you might want to check your motion blur settings in Vue.

I've had issues with Vue reading the camera sync data with a negative motion blur, and you seem to be unable to change this when your camera is in sync mode, so the only solution is to make your motion blur in LW a negative value. This seems to fix the issue and the frames now line up properly, however it is not an ideal situation so I've sent a bug report to E-on.

Hopefully this helps someone.
