Align geo to normals then Blow away

[tveda]

Hi all,

Quick question, if I have a base geo that I'm copying let's say grid's onto it, how can I have those objects aligned to the surface normals correctly? If I comb the base objects normals I can get close but it seems like each grid is following properly but their rotations are all twisted. Some "lay" on the geo properly, others are at twisted angles. I'm basically trying to make a system to cover an object with planes then have them "blow off" via a pop system.

 

Thanks for any advice

Does this work for you?

And to implement the "blow off" just drop down a PopNetwork right after the Scatter. Inside there is a a PopForce that uses the surface normal for velocity to expand outwards, other forces can work too. The activation of this velocity is controlled by an expression $F > 15. So you can pick what time/frame you want the expansion to occur.

Oops! in my haste I forgot to do the POPNET part of the question, my bad!  

@Atom saves the day, hehe.

Awesome thank you both, I always tend to figure something out right after I make a post, but both of you helped a lot so thank you!
