Hi,
Anyone know of a way to have instanced geometry from a parray or something to align to the normals of the mesh its being drawn on. Or perhaps another way to do this?
Cheers,
David

The speed by surface operator has an option to make particles travel out from a surface - do that and set the particles to use a rotation set to speed space follow. If you need them to stop just set a tiny speed amount so they hardly move off the surface and feed them into an event with speed 0.

Thanks for the tip :)
i also discovered that if you use the scatter compound object, there is a setting to make the scattered object perpendicular to the faces of the distrobution object.

Rotation->speed space follow. Then adjust your x-y-z usually in 90-180-270.

hi joconell, thanks for your tips, it really helps when I do some modification. I changed the Direction of Speed by Surface to "Parellel to surface" and the particle can now align to vertices perfectly to a curve surface. I dig this thread up just willing to share with all who looking for this solution. ^_^

to align evenly on vertices, thanks Oleg B. for sharing this:
