I am trying to have a scatter cloud shoot off to create collisions on another surface, and build stuff between them later. Ray node seems to be wanting a direction, but I need that to be dynamic.

How can I get vector information based on point A to point B and plug that into a ray direction?

Thank you so much!

if you want to get a vector that points from point a to point b, you just need to subtract point b from point a. you can further normalize this if you want it to point in the direction but want it to have the length of 1.

the ray direction can take any point attribute, by default i believe it uses the normals. you could store the vector as a normal and it should ray along those.

A file for you
