The Softbody takes over, and the Skin Deformer is no longer in use. If you take other Simulations, the result is different, but the Hierarchy drives the trouble.

My suggestion #1, use a PoseMorph.

Here, you can use a Collision Deformer result, which can be applied after disabling the Skin deformer. Which might lead to a T-Pose. So, you might want to take a copy and, in the sitting position, set the Binding Pose to new.

Now switch the Skin Deformer off and apply the Collision Deformer to the Character. (If you like to show some impact on Character.) The seat must be positioned within the Collision field of the Deformer.

If the deformation looks right, use the Object Manager > Object > Current State to Object (CSTO) to create a deformed copy. If needed, use the Magnet or Iron Tool to shape the Character's details that come in contact with the chair.

Now, you can switch off the Collision Deformer or delete it. The result of the CSTO can now be used in a PoseMorph. Apply the PoseMorph to the Character mesh and set it to Point mode.

Drag the CSTO result into the field of the Poses. I suggest to use "no" for the Alert. Set the Pose Morph to animation and the Pose slider to zero. Switch the Skin Deformer back on.

Now, you can add the impact of the chair to the Character by animating or just adjusting the slider.
Example:
CV4_2025_drs_25_CAdf_01.c4d

My suggestion #2: Do the opposite. Deform the Chair Cushion. Typically, the Barcelona Chair is not very soft, but the impact might be visible.
That means the Character becomes the Collision, and the Chair Cushion becomes the Collision Deformer. Explore the Object>Restore Slider value of the Collision Deformer.
Example:
CV4_2025_drs_25_ANdf_01.c4d

Or, a suggestion combining #1 and #2: Of course, for a close-up, perhaps a little bit of example 1 and much more of example 2 might be a good balance. For the quick Solution, use a CSTO of the cushion and sculpt the contact area into the mesh. For animation, use the PoseMorph options. I leave that to you to explore, no example.

All the best

That is easy to say about your work, mrittman,

Your passion for details and quality shows, and that is motivational.

Enjoy!

Hi Jakob,

I would say that the Egg is close to the perfect shape of the Sphere and, even in the lowest setting, finds good coverage. Since this might be a point of debate, I would like to point to a case that shows how it works with visible changes.

Now, the Documentation needs to be quoted to make the point:
"If set to 0, recessed indentations or recesses or holes will not be included in the collision calculation, but only a single "rubber skin" will be placed around the object…"

The Convex Hull is unlike a Tesselation algorithm that changes with the surface angle, like Adaptive in Spline interpolation.

For example, if you have a hole in the Egg, changes will appear.

Have a great weekend

Hi tie-version,

Typically, I scare people away when I start sharing XPresso options. So I wait a little bit 😉

But here is a way to build a Mixer Console for different areas.

Click on the "User Data" null; see image.
Press play
Explore each slider

Perhaps that is a mix that fits your needs while being interactive.

Enjoy

Thank you, history-growth,

Please have a look here:

My understanding is that these levels target MoGraph hierarchies.

All the best

Hi Dave,

Do you have none of the cloud services mentioned above?

I can set one up in the morning (Pacific Time). I wouldn't say I like to keep an upload link too long in a post.

I will have a look into it.

All the best

Yes, opinion-intnetion,

To my knowledge, Hierarchy works only in MoGrpah objects.

Please use this link
https://www.maxon.net/en/support-center
and please use "Share Your Ideas" to request this option.

Perhaps a Fracture Object as Parent might help, not knowing the set up…

I surely will support this.

My best wishes

Thank you, MaverickMongoose,

Yes, that is certainly not OK.

That is the side effect of rewriting the whole core for speed, IMHO.

We will get back to normal soon.

Thanks for your patience

Cheers

Hi AlexC,

Thank you very much for the file and for using DropBox.

Some of these Spheres fall on the zero-dimension edge of the plane. My suggestion would be to create a box as below. Please note that the box does not need to be seen to work. So you can visually present the flat-based box.

CV4_2024_drs_23_SIsb_01.c4d

I have set up different Sphere resolutions; please pick the one that feels best to you and delete the others.

Please check the Attribute Manager> Mode> Project> Simulation> Simulation parameters; I have increased those.

My best wishes for your project

Hi prompt-height

Yes, that is why the Bullet engine is in Cinema 4D as well. It is not replaced.

Please have a look here: Quick Tip
https://www.youtube.com/watch?v=JwjDc8zIlN0

More about the new Simulation engine is here:
https://www.youtube.com/live/3O22A-hRP0c?feature=share
https://www.youtube.com/live/3O22A-hRP0c?feature=share

So, to a certain degree, you can set up a stiffer object. Look also at the other tips in the Ask the Trainer video.

All the best

Yes, entry-newspaper, that sounds odd. 😉

When I started learning Cinema 4D 25+ years ago, I found, after a while, the Command Manager. Back then, it was filled with "just" around 1,000 items. I went through that list and read the manuals three times over the years.

When I start a hand on class, I start with; I don't know everything. To ease everyone's mind. It is accurate, and no one knows Cinema 4D 100%. Even this morning, I was reminded of a feature I missed mentioning to a colleague's question.

.
Why I'm talking about it? Take the 1,000 items, combine those with each other, and get a six to seven-digit number of possibilities. Combine three or more of them, and it explodes in possibilities.

It is impossible to cover the whole application while being aware of all combinations. I think I'm close, but wait for the next update and then ask me again 😉

Which also means, there is lots to explore that no one has every combined.

Enjoy the exploration

You're very welcome, Simon,

Please note that I prefer the Null/MoGraph Tracer setup over the Spline IK. But it is equally good if the Spline is used instead of the Joints in the Spline IK setup.

Cheers

Hi Bar3nd,

Perhaps you can use the Mesh Deformer workflow for this.
I have discussed this in the older Cineversity forum from time to time, or you can check this link here, fresh out of the oven 😉

Hi background-permit,

So far, I know that would be possible with the Point Cache; after the Point Cache has stored the data, the Cloth can be switched off.

All the best

Hi history-growth,

A clean cut is perhaps more challenging than a chaotic tear. I'm not pretending that I have done it with the new Cloth in any production. So, my example follows the parameters and how to supply the information to the system—my best result from last night's exploration.

You are guessing correctly; the path of points and the combination with the Linear field is the key. I explored if more considerable distances or shorter ones 90º to the cut are better.

I find Dynamics/Simulations undoubtedly intriguing but more challenging to art direct. Sometimes I use the results of the dynamic (point cached) to harvest certain states and then use them as "Blend-Shapes" in a Pose Morph. This is a nice balance between the two qualities.

All the best

Thank you very much, leather-recipe,

Yes, there are post-production ways. Thanks for pointing this out.

As a side note: Back when Twixter (RevisionFX) was The way to go, the suggested use was that already slowed-down footage from the camera resulted in even better quality when "time-stretched" in post. Combining these two might be something to keep in mind.

Thanks again!

My best wishes

Hi loan-pass,

Sure, that makes no sense. I should have double-checked the link. The "copy link" function of the new cloud system didn't work. So, now I fixed it and double-checked it.

All the best

You're very welcome, practice-boss.

Yes, there are many ways to do it, and Forces are just one of the powerful options.

Enjoy

Hi object-kind,|

Please have a look here:
https://www.dropbox.com/s/7ko3rk8kls50ph6/CV4_R25_drs_22_DYxc_01.c4d.zip?dl=0

I have simplified the setup and replaced the cubes with a proxy chain element.

There is usually an option to use a proxy object to have a more detailed model visible, but not used as the dynamic base.

My suggestion here is either cache the solution and replace then the parts or use after caching the Matrix (or a new Cloner) object and use the cached dynamic to drive the detailed version.

I have used the Ornament Sphere here as a Clone, while it is placed based on Cloner> Sort and Plaineffector> Modify Clones (driven by a MoGraph Selection.

You might like to adjust the project Settings> Dynamics> Steps.

All the best

Thank you, James.

When you look at the reveal tutorial at 02:39, you will see that the selection is lost when the plane moves down. That is precisely what we have as a problem above. The Freeze takes care of that in the same way I have described it above.
While set to grow, it needs a starting point: the Sphere Field in this example.

What a bug or a feature is, I leave that to the developers and support. But let's say it works now as it should. 😉

I understand your concern, given that a larger part of our knowledge is now used to identify useable from sloppy information while searching for proper sources; let me say this: Typically, Noseman put's a lot of effort into it. We are in a team and exchange knowledge, and after that, we also have a QA in place. But things constantly change, and then something like the discussion above is needed. Hence why we connect tutorials with a forum thread so we can answer quickly.

In the Q&A forum, you will see me ~99.5% of the time answering only if I have a project file or if I was able to reproduce it. Answering from memory is, from my point of view, sloppy and blurry. It might be right, but is it working with the current release? It always needs a practical check.

I hope that answers all your questions.

If not, please let me know. If not related to a specific tutorial, please feel free to use the Q&A forum.

Enjoy!
