Hi incident-impact,

Sorry, I can't change the inner workings of the render. My take would be that it could be fixed, but then all render times would increase. Again, this is my best guess here.

To get a second opinion, please check with tech support.

Hi chemical-subject,

The image can have only 500 pixels vertically.

To use the Character Definition, one must understand that almost all motion transfers are based only on rotation. This seems to be excluded information in this video.

The key is to transfer the motion size-independently. If the position were included for each Joint, the target character would often "crumble".

The best way is to have the T-Poses as closely orientated as possible so all rotations are transferred with the greatest option to match.
That has been ignored in the video, and the resulting rotations created unwanted motions.

There is no one-size-fits-all fix for that, but to constrain something only with a position of one Joint-tip is questionable, as it might stretch the Joint.

.
If you would like to fix something like that while using the origin position of parts of the joints, I would set up an IK solution for the two joints that define the motion, so the stretch is not forced, and the motion stays hopefully in a believable range. Again, there is no one-size-fits-all solution. This is a fix of a symptom, not of a source.

I have two files below; one showcases the problem when the T-Pose was ignored to set up properly, and the second file uses an IK setup to have the end of the joining chain meeting the same position without introducing stretched elements.

The Goal, can be a child of the Table, in your example, or just positioned there. (I do not have your file nor the image)

Enjoy your weekend

You're very welcome, vincent.hardy.

Thanks for the kind feedback, comfort-sense.

I hope you find the exact setup and enjoy the exploration

Hi Gloria,

Thanks for the file and understanding that I am trying to keep it safe here. I share a lot of files, and the security training I regularly get certainly contributes to my care.

Here is the way I would do it, as it follows the closest to the Helix cable.

.

First, I aligned the ends of the Cable.

Then, I created two handles (see file). Each handle has three cubes; the parent can animate each handle if needed.
The Rigid Tag has the needed setting in the Force tab.

Between the two handles, I have set three Springs. Set Reset length is a key step for the initial setup.

All these cubes are set in Mass accordingly and connected in the Tracer. Connect Elements (no Vertices).

This allows the Spline Wrap to work as it should while holding the Cable ends in place.

The first file is not animated.

Some elements are hidden in the Layers (manager) so you can see what is a key element for the animation

Let me know if that is working for you.
All the best

P.S. I have no idea if that works with your target aesthetic, but I wanted to share it anyway.

Hi Gloria,

As mentioned above, the c4d file is expected, not compressed or altered in any way.

For security reasons, I have cleared that link.

You sent a variation of a Windows zip file, which I will not touch.


All the best

Hi Comfort-sense,

I left the Spline-Mask in the files, as it holds the animation, but set it to be inactive, so it works like a Null only.
The Extrude might be the way to go.

Hi Gloria,

Is this perhaps similar to this question:

https://cineversity.forums.maxon.net/topic/1705/connector-gaps

If you can, reduce the file to the problem (as a copy), then it should be below 1MB and can be attached here as a c4d file.

The Connector is often the better way, but also here, when two ends pull on it, I have only a workaround for it.

Sorry for the following long text:
I have not opened your file; I have no security check for the real. Those shortened URLs put another server in the middle, increasing the risk factor tremendously. Please note that I do not open any Tiny URLs or other shortened URLs, as it is impossible to know what the target is.
I go with full URLs with Dropbox, WeTransfer, Google, Adobe, or Apple; please do not upload it as a zip or rar here. Just the file so it can be checked, then the full URL is pasted here, not encapsulated in an HTML wrapper.
Thank you for understanding.

My best wishes

Hi winner-outcome,

You asked what to do, and the answer is tech support, as I can't change the needed code if that is the issue.
If you have submitted a ticket, I can't see it; please share your ticket number so I can explore what happens.

I do not have a M4, so I have no practical experience.

If you have no ticket open, Tech-support is the way to go:

Sorry for your trouble. Please note this is the Site Issue forum.

Thank you very much for the reply, comfort-sense.

I shared the more straightforward version first to communicate the core setup.

However, I knew that the example video had some "tricks" in it, but that would not have explained the core well, with all the little detailed animations.

If you go through files 01 and 02, it might be easier to see the workflow.

Please do not hesitate to ask if anything is not clear.

It was fun to create the two scenes for you.

Have a great evening.

P.S.: Above is a quick version. If you like to have the round on the right of the Play button, the animation will get a little more advanced.

Hi comfort-sense,

Thanks for the file.

Please have a look here
CV4_2025_drs_25_ANct_01.c4d

Around a triangle, I created a 120º Spline Circle Sector element, and the Spline mask produced the Polygons.

The Spline Mask Object was set to the Triangle's edge location to be used later on and animated for the folding.

This was placed under a Null and then CMD+dragged (copied) twice. This (Sub Group) Null, being at Position 0, 0, 0, allows for rotating so the three sectors create a circle (120º and -120º).

When you look for animated parameters, you will find how easily this can be folded over time.

I also used the Spline Mask-Circle Sector's (Sub Group) Null to shift those three slightly in P.Z. so they do not occupy the same space. If a texture is applied, that prevents problems.

Let me know how that works for you.

All the best

Hi vincent.hardy,

Thank you very much. Your initial file had no animation of the spline itself. Hence, I suggested the simpler version with the Tracer (Cloner/Matrix).

Anyway, thank you very much for confirming, and the file. I had already reported it:
https://cineversity.forums.maxon.net/topic/1775/spline-warp-doesn-t-update-with-animation

I'm glad we have at least one way to get it working for you.

Thanks again!

Have a great weekend.

Thanks for understanding with the URLs, vincent.hardy.

The Spline's information is taken before it is deformed. I tried shifting the Priority up and down, but there was no change.

As a side note, the Spline can be used directly inside the Tracer, no Cloner needed. Just set it to Connect Elements.

This is not
How to categorize it, I can't tell. I will know after writing a report. Since that was discussed many years ago, presumably, a bug would have been fixed by now, but I can't find any mention. As far as I can see, no report was filed.

I will let you know how it goes. Sorry, that might take some time.

Have a great weekend

Hi vincent.hardy,

Thanks for the file.

The simplest way would be to use a MoSpline as a "translator", as the Formula moves only the vertices up and down.

The MoSpline set to Simple Spline can do that. I have also added a Destination Spline, which the MoSpline object produces. It might allow for other options, but it is just an added idea here.

CV4_2025_drs_25_ANps_01.c4d

Is that working for you?

One favor: Please paste URLs just as in the text; I try to avoid these Word Links here for security reasons. People need to see where they go and do it actively. Thank you.

Enjoy your weekend

Hi philosophy-chemical,

Thank you for your reply. I'm grateful for your post's professionalism in expressing what needs attention and change.

I can instantly sympathize with this kind of frustration, which might sound like a rubber stamp sentence, but doing that for so long, I had my fair share of those.

Since this is a forum to find out something works or creative solution, perhaps workarounds:

I typically try not to solve something with questions but rather post files suggesting an option.

I'm limited here, as I can't reproduce this, so perhaps tell me, can you manually set a preview? Does it survive the save and open process?

That would be an alternative, not a solution (at least not in the long run).

Can you see a preview in this file?

Hi Ken,

I'm glad to see you working on another project.

Those things can pull on you, so please let me wish you all the energy I can send to your new work. Please share whatever you like; I'd love to see it.

Based on your initial question, I have put some notes into a little PDF, which I would call a rough draft, and I will expand on it. I hope it can grow enough to become a chapter in a book.
Perhaps it might provide some ideas. This is the first time that I have shared anything like that here.

https://projectfiles.maxon.net/Cineversity_Forum_Support/2025_PROJECTS_DRS/Photorealism_in_3D_The_Lens_Between_Reality_and_Perception_draft_01.pdf.zip

There are surely some additional chapters needed. I will expand it more. Please note that it is a private little thing, not an official Maxon document. So, if needed, the critique goes in my direction; thank you.

My best wishes for your new project

Hi resort-sand,

Thanks for the reply, and the patience with this problem.
