I was struggling with vehicle animation but found a great tool to ease the workflow. I purchased the plug in from the Epic market place for $150 and a $10 chaos enabled vehicle. Had some cockpit issues but the vendor provided quick responses and instructions. There are also some great tutorials on youtube. Anyway now I can easily add vehicles to my movies.
I made a couple of crude shorts... took about half a day once I got up-to-speed on the plug in.
As always, my characters and animation are created with Reallusion Iclone and character creator. Rendering in Unreal Engine 5 and post processing with Adobe premiere pro.
