cute! a little more bit o' details, please sir?

 

I notice that the nail tips bend when they hit the floor. Not a problem for me, but there are some really picky picky people out there.

I dropped a box of nails the other day and wondered if I could do something like that in A:M.

 

I kind of like how these cloth objects seem to be more aware of their true shape than the Newton ones do.

 

They do indeed bend.  I'm finding that the stiffer cloth is set to be , the harder it is for the simulation to finish successfully.

I changed the point of the nail from a small ring to just one CP and that sails through the simulation much faster even though there's many more nails here...

Cool, yeah- who would think to use cloth? Had you tried this in Newton with poor results?

more nails!

 

The first one has the "damping" set to 0.1 and there is quite a bit of bubbling in the nails even after they should have come to rest.

 

The second one has damping set to 1 and there is less bubbling but it might also be because the nails didn't build up such a deep layer.  Notice that the motion only happens when nails are on top of other nails. Single nails on the ground stay put after they stop moving.

 

The third one is amusing for the one nail that gets somehow launched high into the air.

excellent work. the fact is there are some animations stilling on the vidéo, after the nails finished their shut down. perhaps too many but with the eye of the animator (poor one) i am i can see some animations at the end are too much. but exellent vidéo, i can 't wait for more

That would be the "bubbling" I mentioned.  Yes, it is undesirable. :(

 

 

how did you the render ?

 

 

The lighting is the default setup but I turned off the "Key" light and the "Fill" light and used Ambient Occlusion (AO)

I also just noticed an orange nail near the front that decides to flip itself at about 0:32  :lol:

The duplicate wizard!  

 

I'll note that the dupe wizard won't work for things that need to have a decal copied also.  clever.gif

This must be an advantage to using the cloth method over the Newton Dynamic method. The Duplicate wizard only works in the model window(apparently), and ND needs the model to be centered-up on the XYZ axis's.

To do this animation with ND would require importing each instance of the nail into the chor and placing them in the XYZ dimensions (and rotating them) one by one. Pain in the Butt!

 

Begs the question... could the Duplicate Wizard be made to be available in the Choreography?

Did a quick test with ND for comparison... I had to drag 20 instances of the nail into the chor and place each one of them so they were not overlapping one another. As far as the collision-detection of the shape tho...I don't think this is lacking at all.

Those look good! You're the Newton King!

 

I guess you can have up to 2000 Newton objects?

 

 

Begs the question... could the Duplicate Wizard be made to be available in the Choreography?

 

 

 

Try the "Multiple Copies" or "Multiple models on Path" wizards.

Nice.    Matt  on your question on adding multiple model to the chor  did you right click on chor pick wizards and multiple copies  ..they show up together but can be arranged

Thanks- yup, I see it now... that saves me from dragging multiples in. I like the way the other wizard sets them in an array... would be great to have some sort of mograph in A:M... dreaming!
