Physics timing is different in PIE vs Exporting movie?

Hi There,

I am new to the engine and i’ve encountered a problem that I don’t know how to solve. I am trying to create a cinematic of a vehicle driving through an environment. The problem is that when I enable the simulation and play my sequence the vehicle moves at a certain speed, and I have set up my camera to follow based on it’s approximate location. When I go to export a movie, the truck accelerates way faster and my cameras cannot keep up.

How can I make sure that the timing is the same in the preview as in the exported movie?

The vehicle is rigged using the Chaos plugin and it’s steering is being controlled using a spline. I am controlling the throttle and braking via keyframes in the level sequence.
Does anyone have any tips? Any help would be appreciated. Thanks!
