velocity Growth propagation : add velocity

[Korben]

Hello all,

Any idea how to add velocity to a growth propagation ( from bwdesign tutorial ) ?

Here is a sample file, I don't know what to do.

I would like the points to have velocity ( in the direction of the growth... )

thanks.

Here is a sample file without velocity of course

I guess that's what you were thinking about

growth_Vel.hipnc

Thx Shinjipierre,

I was thinking about that, yes

But, in fact I would like to convert thoses points to poly and to have consistent motion blur on it ( > Maya > Arnold )

Any Idea on how to have a more "stable" velocity ?

Btw the mesh is actually not motion blurred in Mantra, can't understand that.

thanks a lot

Something like this?

growth_velocity.hipnc

 

Deformation blur turned off by default:

Yes that's it !

 

Btw it's not working that way with my full scene ( the scatter source is much more complex than a grid and not at the origin of the world )

Will investigate that and probably come back with others questions

thanks a lot
