Thank you very much for sharing this with us, be sure that this will be very useful and will save a lot of effort and time for those who face the same issue, I don’t know if you have tried the Reality Converter pro that I mentioned to you in the previous post, it is free, you could export the file from the cinema 4d in Obj format and then take it to Reality Converter to get an usdz file that works on the VisionOs better than the usdz exported directly from the cinema. Just if you want to try it otherwise the problem seems so fundamental that it can only be overcome by finding a way to record the movement of the mesh and delete the joints as you stated from the beginning.

Good luck! let us know (when you have time) what you got.

Hi Eric,

I didn’t quite understand how you wanted to do it, but if I understand the goal you’re looking for, then the tutorial below at 31:09 contains techniques I think will be helpful to you.

Let me know if this works with you.

Thanks for your appreciation! honestly I don’t have an explanation for this, this may require an Apple expert to explain it, but it is known that Apple is picky and they are selective in what works on their devices. Exporting the usdz file from the cinema 4d may not work and it is better to export to Obj and then pass it through the Reality Converter pro (which is completely free) to get the usdz file, but even with this, it seems that there are limited areas, an other thing it’s also seems that Blender is more fortunate in working with Apple vision, it may be used as a mediator between the cinema 4d and the VisionOs.

I hope this is useful to you.

Always happy to help you, Mauricio! I understood you very well from the beginning your presentation of the problem was clear, I don’t have much knowledge about Unity but I assumed that since it reads the Skin deformer with the bone structure it might be converting the movement information to the mesh so that if we convert the same file again from Unity to Apple Vision it can read the movement, that’s the idea, the video you shared with me might be misleading and its owner didn’t explain the method so I don’t advise you to waste a lot of time trying to simulate it especially since Unity experts say that so far there is no way to convert the deformation from cinema 4d except through Skin deformer, please let me know if you have tried converting to Apple through Unity and what results or obstacles you might have encountered.

Thanks for your appreciation! Yes, you can do that by using the object again with the Offset Fragments option in the Voronoi. I have put a screen recording below explaining that. Let me know if this is what you are looking for.

Hi Mauricio,

I mentioned in a previous post with you that Unity reads Skin deformer with a bone structure, you could bake the animation and convert it to Unity and then Apple Vision, maybe that makes it read the animation, I tried several ways to transform the movements of the joints to the mesh but nothing worked for me except using the Retarget tag as in the screen recording below, but I don’t think that will lead us to move all the points of a certain model according to the movements of the joints. I hope this is useful to you and let me know please if you come up with something.

Hi Matt,

If you don’t get the look you’re looking for with the Voronoi generator you can use the same object as a fracture distribution source or any other object you want I’ve put a video below explaining this, let me know if that fixes it.

If you could you post your file here, or at least the part related to the texture that will be better.

You’re most welcome, Chris! I was very surprised the first time when you told me that the script didn’t work, but I said maybe there is something in your system that prevented that. I’m very happy for you and thank you very much for sharing with us what you get it.
