I need to create a particle systme that takes a sphere-oid shape and extand as such. I've tried omni, volume, and surface from a NURNS sphere. None of them give me what I need. The all look too random. What I want is for the particles to all be evenly distributed. Kind of like the way directional works, except that the partcles then need to expand along the directions of the normals of the sphere, not in one direction.

I also tried using the radial field, but because of the gravity and drag assigned to the particle system it couldn't find the center of my shpere shape.

Any thoughts?
