Coffee Jar seal peel

Recommended Posts

I'm not exactly a newbie, but I could do with some advice regardless.

I need to peel the seal off a coffee jar in a convincing manner, but due to the shape of the foil, I cannot get a perfect peel action. I want this to look awesome with no stretching or distortion. Has anyone got any suggestions as to how this would best be tackled?

I have tried character rigging it, I have tried various deformers. I used vertex mapping to control the transitional shape. I have tried building the foil with different meshes to make it more efficient, but can't really get it to behave as I want. Admittedly I'm no great aficionado with character rigging, deformers or vertex mapping, so I concede, I'm probably missing a few tricks.

Here are some images that I used for the storyboard - hopefully these explain the shape of the foil and the peeling action that I want. It's quite a satisfying feeling when you peel it in real life and I want to get that across as best as possible.

Please help me C4D geniuses! Huge appreciation in advance

Have you tried pose morph tag?

Creating key poses by moving the mesh points by hand as per your storyboard and animating between them?

This is not entirely right and I haven't got time right now to take it further, but this might be a direction you want to investigate...

    I never would have thought about that solution StCanas! I will have to do some messing about to see if I can get it to fit, I think the main stumbling block will be the requirement for the curved shape of the laser cut on the foil, will let you know if I have any success. But thank you! I really appreciate that, proper outside-of-the box thinking!

    Thank you Mjohnny, yes I tried the pose morph tag and I couldn't get it to play ball. But maybe I should have another go now that I'm desperate! Really appreciate your help.

    It's an interesting problem, for sure. Might be one of those things who's difficulty is out of proportion to its apparent simplicity. And if you want it very realistic then the outside edge has to stay stuck to the jar lip until the circular upward pull arrives at a given point as it circles the lip. Jesus, it's even hard to describe! Lol!

  • This is my best attempt so far - pretty shabby TBH

    Yup, I'm glad someone else sees how much of a rod I've made for my own back! My contingency plan is to use creative camera angles to mask the sh*** bits ...

    Hit play to see it run and switch off the deformers to see where it starts as a flat plane. I think this will work if you just shape the ends of the plane.

    An interesting and tricky problem to have, can't quite get my brains around it but I wonder if there is any milage in this method of two helix in a loft. My animation skills are dreadful  but here is a test file to illustrate the point. Couldn't quite get my head round which bits to animate but could also scale the Y axis of the whole loft to flatten it off.

    Thinking about it now, it would be better to set it up upside down so that when the spiral rises up, you could then reduce the height of helix to make it pop up. left a hole in middle at the mo so you can see whats going on.

    Just my thoughts on a possible alternative, apologies if you have already covered this method.

    Hi StCanas, the problem with this method is that it is vertically distorting the foil in the centre, then throw in the requirement for a curved laser cut and I'm just not sure it's going to work - huge thanks, but so sorry :(

    Thank you Deck, that looks promising. Again I never would have considered this approach. My concern is that the client requires a very specific laser cut in the foil and I don't think I'll get away with any variations on that theme. I will have a mess about with your model and see if I can reconcile the two. Really good suggestion :)
