Hello guys,

I'm having some hard time to build the ‘correct’ vector for this system (attachement).
The result I'm looking for is a ‘perfect’ orthogonal/parallel orientation of the copied elements (the small cubes).

I have tried all the possible combo using the polyframe operator, but there is obviously something I completely miss.

Any advice is more than welcome.

Thanks.

Pascal.

Ok I have a super dirty solution.
Looping through every faces, and building an up vector based on the first 2 points.

I'm still interested to see a clean method

Cheers.

Try the attached - the main issue is that you need to stop the interpolation of the vectors when you scatter points, using an attributetransfer allows you to do that.

This page has all the attributes that copying uses:
