Hello,

is there any simple way to make debris to spin according to velocity?

Any help??? or there is no solution??

Hello Debadas.
I looked at your HIP file and fixed that.
Attaching linear velocity to angular velocity isn't great idea because when particles hit the ground and bounce it off, direction of linear velocity vector becomes upside down hence direction of spin will change and result won't be good at all (I did it in this HIP file).
In Attached HIP file I explain where you can write expression.
hope this helps.

Hello Nima,

Thanks for the reply and the hip file. But this not what I was looking for exactly. Its not looking natural because debris are not rotating according to velocity.

Every piece of debri is moving with different speed and direction so those has to inherit that value and should rotate accordingly with different speed and stop when velocity is Zero, which is not happening in your file.

May be i am missing something here. So please let me know if we can control derbies fully and look natural.

Simply you can write something like this in popspin1 node:
You can play with it and write whatever you like in that area.

Thanks Nima,

Its working perfectly..thank you so much..
