Great!

One more thing. I don’t believe I corrected the chassis rotation within the rig itself. After baking, I simply opened the Animation Editor and dragged every key that was above 5 degrees down to normalize the animation. If not, you might encounter the same motion blur issue I experienced in my initial render in this post.

You’re right. I’m not a rigger myself, so I overlooked those mistakes.

Upon closer inspection, I realized that “FL1” and “FR1” should output “Rotation.H” rather than just “Rotation”. 😅

Oh man… this is a bit embarrassing. It doesn’t work on my car either, and I never noticed because I used a relatively straight road for my animation.

I realized I had to connect the rotation of FL1 to the “rotation H” of Wheel FL, not “P”. After making this adjustment, the controller constraint is functioning correctly again. However, when…

I’d be glad to assist you.

Hmm, did you create a new XPressor tag or modify the existing one?

I recall encountering issues with positioning the controllers on the wheels. I believe I disconnected the controllers from the rig, adjusted their placement, and then reconnected them.

Regardless, if you’re still experiencing difficulties, I could send you… Read more

Hi Ryan,

In the end, I found it necessary to add some extra nodes in the XPressor. For instance:

By default, the “Wheel FL” null, containing the mesh, had a global rotation constraint with the “Circle fl 1” controller. This controller manages both the rolling and steering rotations, but it’s limited to global rotations, causing issues with motion…

I took a closer look and noticed that the Xpresso rig controlls the wheel controller with local rotation coordinates but transfers global rotation coordinates to the mesh. It works great until you bake it. At the end I had to adjust a few things in rig and now it works.

Thank you Brian!😃

Hi,

For my recent project, I purchased a fantastic car rig with some dynamics, and I plan to render the animation on a cloud network, so I need to bake the animation.

Here’s my issue: when I, for example, bake the animation of the chassis, it looks fine until I hit render. The chassis rotates itself every few seconds in a single frame, and it gets…

Okay, I had still these issues. I think the rig system is somehow buged. (Cinema 2023.2.1)

I choosed to buy a car rig from Gumroad and it works much better:

Hi Kouraib,

Thank you for the suggestion. But after hours of troubleshooting, I discovered that the spline controlling the car animation is the main issue. As the spline is beneath the displaced surface, the wheels sometimes don’t make contact with the surface.

Therefore, I attempted to project the spline on top of the displaced surface and added a…

What do you mean by “bump”?

Hello everyone,

I’ve completed a car animation, but during a test render, I observed inconsistent spinning of the back wheels (see attachment). I utilized the car rig system in Cinema 4D, and it works as intended. However, when I define a ground collision mesh for the car, this spinning issue arises. I also noticed that the collision detection is…
