View Full Version : Particle Instancing along normals

I have a blobby sphere that needs little spikes coming out all around it. I figured the best route would be to have the particles appear at birth and live forever, and stop the rate and hold on the surface, and then instance the geometry onto them. But I have no clue how to conform them to the main surface's normals instead of just aiming at the same direction they're modeled in. Any help would be much appreciated

Hey Oglethorp.

Try making the blobby surface a goal for the particles. Orient your spike object along the X axis and freeze its transforms. Make it an instanced object.
set the goal weight to 1.
Create Goal U & V, and set them to rand(0,1).
Create Goal world normal PP.
Go to the instancer attributes and set that Aim Direction to the goalWorldNormalPP.


Hope that helps,
