I'm trying to put an object on the vertices of another object (crosses on a sphere) but I would like all the crosses to be parallel to the sphere's surface, not sticking out.

This is my current setup (using particles):

In the "Rotation" panel of your particle system, choose "Normal" as your "Initial Orientation" (and possibly Phase: 0).

If your crosses are now sideways (this might not be your case), edit your original cross object in Edit mode (Tab) and rotate it so that it lays on its side.

Better explained with pictures:

(P.S. as pointed out in the comments, if you want the particles to stay in place you should set "Physics" to "No")


Edit: in the comment you mention that you would like the "cross" instances to follow the sphere during animation. There are three different approach to this problem, which I'll not explain in detail as they are not the topic for this question:

  1. either Apply the "ParticleSystem" modifier: this will make all the crosses real objects. Then you'll select all this objects and the sphere, and set parent (ctrl+P) to make they follow the sphere.
  2. or make a ParticleSystem of the "Hair" type instead of "Emitter". Several settings must be changed then.
  3. or don't use a ParticleSystem at all, and use DupliVerts instead.

  • $\begingroup$ I was trying that, but in object mode so it didnt work at first. $\endgroup$ – Срђан Хрњак Mar 25 '18 at 13:52

    $\begingroup$ @СрђанХрњак In principle, you could do it in object mode, provided that after rotating you do Ctrl+A > "Apply rotation". That wouldn't allow you a live preview, though $\endgroup$ – Nicola Sap Mar 25 '18 at 13:54
  • $\begingroup$ Any way to keep them aligned during rotation of sphere (animation)? They are rotating around its own axis too. I tried to set the same animation for origin object itself (36 frames 10 degrees each) but without effect. $\endgroup$ – Срђан Хрњак Mar 25 '18 at 19:02

Use "align rotation with the snapping target" in the footer of the 3Dview. You can choose dot or plane for snapping your cross. See image joint: snap.png.enter image description here
