Hello Dr. Sassi,

Thank you for that. I eventually figured this out, thanks to a clue you provided.

For anyone looking for a solution to this, here is the project file:
cv4_2026_drs_25_siff_03.c4d

The key is to have a copy of the spline, which creates a force pulling towards itself, to counteract the centrifugal force.

Thank you. Sadly, these are using the Absolute velocity, which gives the ball a constant speed. The reason I'm trying to work out how to use "Add to Velocity" is to achieve natural motion while being able to influence it more precisely. Is it possible?

Thank you! That is using the "Change Direction" force type. Are you suggesting using a mix of "Add to Velocity" and the "Change Direction" field types with two separate field forces?

I'm keen to figure this out using "Add to Velocity" instead of "Change Direction" to allow for more flexibility and more natural motion.

Hello Dr. Sassi,

Hope you're well.

I have a very simple scene here: https://www.dropbox.com/t/fpztcYwh1jJBYo1S

What I'm trying to do is make the ball follow more closely the curve using "Add to Velocity".

I like the idea of controlling dynamic simulations with field forces with the "Add to Velocity" type, but I'm struggling to understand how to make it follow the force more closely.

Thank you,
Robert

Hello Dr. Sassi,

I have a scene with a simple setup: 3x cloners shoot out papers and then fall being affected by cloth dynamics. All works well.

But, when I cache the scene, only 1 of the cloners seems to cache correctly but the other 2 caches in what appears to be a lower frame rate and then freeze.

This seems to have happened at some point when I was working with the scene. I've cached it before and it worked fine.

I tried creating a new project and copying everything over but I'm getting the same results.

Here is the project file: https://www.dropbox.com/t/ihtTplgjV86P71Ve

Any help would be appreciated.

Thanks,
Rob

Hello,

I'm using the Mixamo Control Rig with a rig very similar to the Mixamo one, the difference are a few extra joints, please see the selected joints in the screenshot.

Everything works fine with the rig, just those joints are left behind. I thought of including the extra joints in the bind hierarchy as seen in the screenshot below.

This works, but the forearms behave strangely.

I wonder if there is a better way to make this rig work with the Mixamo control rig.

Thank you,
Rob
