Awesome

Newbie here….what should I watch next to apply this to a character, specifically a imported MIxamo character? ON that subject can you help figure out why i can keyframe let’s say a head object parameters but my actual character doesn’t react? this is from a tutorial for ej from School of MOtion…all works well except my actual character doesn’t animate only the’rigging’?

Many thanks

Hi Mark IN MN,

I have moved this to the Q&A. This seems to be more a question of any steps after this tutorial.

Would you mind to share your file (zipped and attached here) so I can explore it? I can only guess otherwise, and that is not what I believe to be anywhere pro-like and wastes only time on both sides. So, always a project file. Thanks.

I think you should ask questions about tutorials from the School Of Motion in their options to get support for the content they have created. However, at the moment I get a file, I will look into it.

To find more about Mixamo and Cinema 4D, you can place Mixamo into the tutorial search (right upper corner, the magnification glass) and get a list of material, like this one:
https://www.cineversity.com/vidplaylist/mixamo_to_cinema_4d_character_workflow/

Mixamo gives you for every character a standard but specific rig, e.g., I have a character with four fingers (a frog), and so I got only four fingers from the download.

All the best

Mark_IN_MN,

You certainly do not drive me crazy, and thanks a lot for the very kind feedback. If I have no answer right now, then the questions will help me to grow. If I have an answer, I’m happy to share it. Nothing that drives me crazy, as I know, that a problem comes back until it is solved. I love to solve problems, as I see in the long run, how much beauty is produced here by every single artist. So, I look forward to every question. Including yours, of course.

Thanks for the file. I had more your iPhone/iPad results in mind: the Character Rig. (Sorry, my fault!) I do not have a current iPhone that can produce it.

From the preview in the introduction, it looks very similar to the Maximo Rig.

Before I start guessing and wasting your time, I wanted more to have a look into the data that you get. With that, I like to set up a file and perhaps create a little clip for you.

I have written to the developer to share a standard set up with me. Since we are in different time zones, that might delay my answer a little bit.

Cheers

Not sure if there is a place to submit a feature request so I will put this here in hopes the right eyes see it.
It would be nice if I could transfer my captures to the cloud, then pull them down to my PC. I am not allowed access to the same network as my work PC, so I can not test the app beyond creating captures. If I place the capture in the correct folder, it should pop up in C4D as an available capture.

Thanks,
bsides

Hi bsides,

Not the right place, sorry, but since I got this tip from the developer today, I’m happy to share it here (Thanks to Kent! … in so many ways!)

“BTW: You can get any users to email you their capture directly to you from their iPhone or iPad. “

I asked Kent to send me a capture file, so I can answer here, and he did! So, I took the zip file as it was, and dragged it to the plug in the field. That was all there was to it. Instant success. So, I think that should work for everyone who can receive emails.

ENJOY.

Mark_IN_MN,

So, I got from Kent a demo file. Which helped me to see how the Rig was set up.

The Rig is quite different, but since it is based on a biped, quite solvable. In short, I loaded the complete Rig in one link list and sorted the Mixamo rig in a second link list. Needless to say, that even the total amount was different.
Anyway, I hope I got it synced, and it is ready for a beta test. Hence my request for your motion Capture as it is from your iPhone/iPad.

Screenshot:
https://www.amazon.com/clouddrive/share/poWweA7cvbAov6UiC6SINHYQ6cnpLtwkjhmaq2YvIYb

The idea is here that any file you get from your iPhone/iPad needs to be turned into an Animation Clip. Which is typically a work of a few seconds. This clip can be used then on my converter file to drive the two rigs.

If that works (fingers crossed), one can harvest a second Animation Clip from the connected Mixamo Rig. This animation Clip, as the other one, can be saved, distributed, and used in many ways.

I do not promise anything at this point, but I have a good feeling that it might work. One thing must be clear, e.g., the Spine has more joints and to reduce this might have in extreme bend poses a squeezing effect.

All the best

hello Dr. Sassi, I am trying to connect the face tracking I did with I phone to a different face model in c4d. how can I do this?
many thanks for your reply.

Hi Lorenzo,

Would you mind sharing this file? I need to see your data, including both face geometries.

I have sent you an upload link.

Cheers

thanks for your help, I ve uploaded now the files.
I am not sure if the face scan model I did is wrong as a complex polygon mesh.

let me know. thanks

Thanks for the files, Lorenzo.

The MovesbyMaxon file opened successfully, as did the obj. you have sent me.

Since these are two completely different meshes, I need some time to look into it.

I will post here with results if I have something figured out. Thanks in advance for your patience.

Cheers

Hi Lorenzo,

I assume that the target mesh is not prepared to receive the data for the PoseMorph. This would be the way to go, of course.
https://www.amazon.com/clouddrive/share/mnJWVFGIeXLHij7GXGX1cI43kdGW0JngGpFR72yiPW5

To transfer data from one to a completely different mesh requires some decisions. If we exclude the PoseMorph (as suggested int eh MbM help file), then some work needs to be done. I have attached below a simplified version and a screen-shot.
Files:https://www.amazon.com/clouddrive/share/3QhTbNfOw0dWdN2DTQpCqKmwhazmUCjKFKOZegPpolu

First you have to create a Joint.start and Joint.tip and clone this with a MoGraph Cloner. Cloner source is the MbM face-object. It can be done for each vertex/point or via selection and other options.

The idea is to make this Cloner editable and Bind the Joints with the More dense object. Then Auto-weight, and perhaps Smoothed. (Always have an eye on the scale/size)

To have the joints moving the given face, it needs an iteration (Xpresso)

In your case, the mouth needs to be manually weighted. It was not possible to open it. To work with fewer than the 1000+ joints is undoubtedly preferable. (My hint with the decisions…)

I had initial concerns about the Head movement, but the weighting transferred that as well. It should be noted that studios mount such a camera to the head, so the face is stable in the image, and only the expressions are captured.

My suggestion, I would use the PenTool and create a lower res model from the head. This fine mesh is not ideal at all to get those things working.

If I find anything else that looks promising, I will share it.

All the best

You’re very welcome, Lorenzo, thanks for your reply.

With fine meshes like yours, as mentioned, retopologize it. Perhaps, use at least the Smooth Deformer.

Screenshot (I do not share your file, it seems private, but I have sent you a link.

Lorenzo, thanks for the feedback and your input, last night, on what you like to do.

I know I just double here the entry of the manual. However, I know that a one minute clip has often shown to be very useful to point into one or the other direction.

So, I took a model from the Library and applied just two Blend-Shapes/Pose Morph on it. Of course, there is an option to get all of them at once into the Pose Morph.
Just keep the sequence of steps, and it should work fine.

Since I have done it a few times by now, I notice that sometimes it needed to be (PoseMorph) clicked a few times to Edit, then to Animate, then to Edit, to make it work. At the moment I find a repeatable reason for that, I will file a report.

Here is the clip. As short as possible (one minute clip #907)

Enjoy your project
