I use scatter to create some points on a sphere, how can I move those points a lone the sphere serface without rotate the shphere?

Several straightforward ways I can think of.
It could just be a matter of merging a transform below your scatter, to rotate the scattered points, with the original sphere, then put the display flag on the Merge.

Or you could Ray the points onto another sphere, use “closest distance”.
Or use a nurbs sphere and Creep the points on that sphere.

or you can do a old way and use 2 sphere,
copy 1 on the top of the one that you have and use this one scatter the points,
so you can move and rotate the scatter points and in another node having the “Real” sphere,

but the idea of appending a transform node for just the scatter points sounds even better .

Thanks, but all points will move in the same direction in the both way. I want points move randomly on the sphere with different direction and speed. is there any way to do it?

see attached, this should work with anything that has UVs that
unfold into a square plane.

Otherwise you could just have an animated cloud of points and
ray them out onto a large sphere (set animated point normals to
$TZ $TY $TZ 1st) then scale down.
