Hello there…!


I try to animate toothpaste on a curve, my problem is that the form is too "perfect", I'm looking for something more "organic". I did some testing with MoSpline, Spline Wrap, sweet nurbs, I do not get what I want. For now the closest to what I search it with Metaball / MoSpline, but I have trouble with the texture from that solution…


Do you have any tips or ideas how I can get to something nice?






Merci,




Charles

Not sure how much animation you are doing but I would try to keep the geometry simple and use a shader to give your toothpaste a little more variety. Try using noise in the bump channel and/or a sub poly displacement to get a more organice look. Seems like a simple sweep nurbs with some tapering should do it, but really it's tough to say without knowing how complex the actual animation is.

Of course, Realflow is going to give you the best output here, if that's an option go there.

Maybe Nitroman's "Magic Paint" freebie plugin would help:

Also, I had a project where I needed to create a "nurdle" (LOVE that word) of toothpaste. Here's my file:

I would approach it using sweep nurbs or a simple spline wrap. I would use a displace deformer for a more organic feel on the surface and possibly a melt deformer to fake the liquid effect of toothpaste as it settles. But similar to what mshadis said, my approach might be different depending on the complexity of the animation.

Thanks for your answers. I'am new to this forum, and i have already feedbacks from you, merci… i'm gonna give a try to your suggestions and see what i'am able to do.
TO get a idea here is the "animation" of the toothpaste :

https://www.dropbox..../ToothPaste.mov

The "direction" of the entire animation is for a comedy show with for sponsor a famous brand toothpaste. Here is the deal: do somethings that not to "dirty" to promote the brand and in the same time find way to do somethings funny… Voilà for the story of this.
Thanks again

Charles
