Are the orientation matrix of sphere particles the same at the begining of generating particles?

Hi

I want to make sure that, in the packing consist of single sphere particles, are the orientation of all particles at the begining of generating particles the same?

Because when I looked through my simulations, all the orientation matrices were [1,0,0;0,1,0;0,0,1].

Thanks

    Hi Raheem,

    By default the in-built factories create particles in a random orientation, however if the orientation matrix for all particles is as you mention above then all the particles orientation is the same, and this matches the orientation of the particle prototype in the Creator.
