Hey!
I have encountered a problem for several versions of Unity in the VFX Graph.
Until version 2019/2020 I had this type of rendering on a point cloud that I imported.
I use the Position function (Sphere) so that each point is duplicated at a distance n following the path of a sphere. This allows you to have this nice halo effect!
However, since version 2021/2022/v6 everything seems to collapse into a single sphere.
I searched through the different options, but I can’t find the same layout of my point cloud.
Can you help me? It’s very frustrating.
THANKS! 
In Unity 2019
In Unity 6
In VFX Graph
Not totally sure about what I’m seeing here, and I’m not familiar with VFX Graph version priors to Unity 2022. Now, when you select your Position Shape Sphere, what is the composition Mode. From what I understand, you should set it to “Add”. By default, when you create this block, it’s on Overwrite which will set your position into a Sphere shape, disregarding the position previously set.
I hope it helps. If not, let’s continue this discussion. 
Thanks for your answer!
Unfortunately, there is only Set option for Position shape . 
With the block selected, look at your Inspector window.
Well, I put the Position Shape in Set then I put Add Position from Map and it works well.
Thank for you tip!
Glad to know that your issue is solved. Have a wonderful day.

Hi, I’ve also came across this issue however none of these solutions seemed to work. Any ideas on what I’ve done wrong? The particles spawn in a sphere shape but as they get pushed outward they form back into a cube shape.
Hi!
In your case, the shape position is fine, but the particles are given different speed depending on the movement direction, which results on that cube shape.
With Velocity Random (Per-component) a particle could have a velocity like (0, 10, 0), straight up with speed 10, and another could have (10, 10, 10), moving towards the diagonal with a speed of ~ 17.
I think what you want instead is to have a fully random direction and then adjust the speed:
Hope that helps!
Have a nice day.
P.S.: For future issues, it is easier for us to notice your message if you create your own post (and then link to other related posts if needed). Cheers!
