Any thoughts?

Thank u!

Hi thanulee,

Here is an example that I have roughly set up based on your image.
Note the order of the Deformers and its setting to keep the Y length.

The sealing is done with a Correction Deformer.
Here you have to make certain to move the Falloff only with the Offset parameters.

I moved the points a little bit towards the center of the package, as the fold down would lengthen the polygons otherwise. I assume that here is your problem, polygon stretching, but assuming and guessing is not really what I like to do here.
Note that stretching any polygon will stretch the texture! The UVW information is connected to it. Since no on is really interested in the texture when it can’t be seen at all, the projection should be done when the object is in its final state. While folding one might see the texture, but motion blur will cover this a little bit up.

As usual, images are nice but not really helpful. A file reduced to the problem is much better. Since I had none, here is my example:

All the best

Wow that was fast! thanks a lot! Sorry i dont have a file to send, cause i just started researching this, but what u send is a great start!! thanks again!

You’re very welcome, thanulee.

If there is anything else, let me know.

Enjoy your weekend.

Sorry to bother again with this hehe. I have a picky client and he keeps revisiting my wrap animation.

So I d like a though on how to do something like this at 0:13 https://vimeo.com/31201968

Also I havent found a way so far in c4d to reveal polygons without opacity maps, i use boole for that. Is there any other way? thanks a lot

Hi thanulee,

I have no idea what you mean by “Also I havent found a way so far in c4d to reveal polygons without opacity maps, i use boole for that.”

You mean an alpha channel, or perhaps a Weight Map growing while using in in a Vertex Shader? (For transparency or Alpha).

The clip @0:13 shows a very quick wrapping, you could use nearly a blend mode in a Cloner for that, while having the different states as child under neath it (perhaps 12 steps?)

Let me know if that fast animation is what you are after, and please share a scene file with the polygon/reveal. I’m happy to look into it.

Cheers

Yes exactly that fast animation i am after i ll upload a scene soon for the polygon reveal so u understand what i mean thank u

Hi thanulee,

If you need an upload link, please let me know.

Cheers
