Selecting the particles inside of a sphere.

[SuikaSukiyo]

Hi,

There's no tool that would allow you to select all particles in the center of a sphere, that's very specific. What's your use case? Maybe it would be simpler/easier to create the particle group at runtime, given any specific condition you want the particles in the group to meet?

kind regards

Thank you for the quick reply. 
I was trying to make a ball with a relatively hard core compared to its exterior as an experiment to learn the tool.
The eventual use would be to select particles relative to a bone and surface position in order to easily edit different groups. 
The FBVS already exists for this purpose but I haven't tried it yet. 
Could you please point me toward how to interact with the particles within a BP in code? 
And a method to interact with the blueprint editor window?

I think it would be very useful to have primitives that act as selectors. 
For my exact case, a sphere that can be centered and then used to select a group of particles.
This could also be extremely useful for complex skeletal particle groups such as using a capsule to select bicep muscles or other shaped grouped.
