Mixing Weight map mesh with gravity

I’m working with a character that’s has a cloak (like Emperor Palpatine from Star Wars). The cloak was a weight map so it moves with the underlying body. My number one problem is the cloaks sleeves. The Cloak mesh is modeled where the sleeves hang down. When the arm is animated the hanging sleeves ‘defy gravity” and point horizontally.

Is there a way I can make the specific part lower part of the cloak sleeves always translate down without destroying the weight map of the rest of cloak and sleeves? Kind of like selecting the specific polygons and making the cloth or soft body dynamic? Or do I have to make special bones that somehow added and transfer hanging sleeves polygons weight map to the added bone?  A special morph?

Hi brucek5,

Yes, you have the right idea with a unique morph.

Why not using a PSD Pose Morph on this? So the arm moves and the sleeve changes.

Example (simple)

Perhaps add a Jiggle Deformer to it (probably with a restriction tag and weighted) to get some extra natural motion.

I hope that keeps your rig simple.

Cheers

P.S.: I saw from time to time that extra joints were introduced to manage such different mesh moves.

Thanks Dr. Sassi for the very quick reply! Looks like from the example filename of your example it’s for R23. My project is in R21, does the example use capabilities not in R21?

You’re very welcome, brucek5.

When you open it in R21, you will see an alert that Magic Bullet Looks is not available in your version.
What you miss out is the option to adjust the render results. Which is not something this example needs nor use.

I have open it in R21, and it looks to me precisely in the way it looked in R23.

Same Manual entry even:

Enjoy.

I’m still struggling with PLA morph. One of my major problem is editing. In the attached screen capture, you can see the cape budges up when the character is sitting, but when I edit the mesh for the mesh, the cape returns to the t-pose position which makes it hard to know what points to adjust. Is there a ways to make the edit mesh tools not revert to t-pose?

Hi brucek5.

I’m not aware of a default PLA Morph, nor is the Help Content. (Correctional PSD Morph?)

What I assume happens is that the
Attribute Manager> Mode> View Settings> View: Deformed Editing is not checked [off].

Screen-capture (scene 0-45sec, View Setting 45-48sec, result 48-60sec)
https://www.amazon.com/clouddrive/share/iZ19KMjryCtR3mcB577bLJcM0HzKdbNUFElrCdT5CjO

Can you confirm that?

Cheers

Hi Dr. Sassi,

You must have a PhD in customer service too!.

The PLA was a typo.

I must only know 2% of Cinema 4D, I whish I knew of the Deformed Editing option years ago.

I think the video you made will enable me to figure this out. Thanks.

Thanks a lot, brucek5, very kind of you.

Typos happ3n. wink

Hehe, I love to share and explore. To have seen the thousands of projects that got stuck on small or larger things, then moving on to be what the artists intended to be (or better) fills my heart.

I know how it feels to get treaded from a weird point of view. Nothing that I ever want to give anyone here.

We all love to create, we all have different ideas. I do not see the sharing as a loss; I see it as a win. I learn from every question.

Enjoy your project.
