Hi guys.

Is there a way to create a particle system from the 3D point cloud or at least map the co-ordinates of an existing particle system to a point cloud?

The particular application that I'm thinking about is if you had a 3D tracked Drone clip and you wanted a location pin graphic to spawn at different points that are in line with the point cloud. I have been doing each graphic manually and I wondered if there was a more efficient way to do it.

I'm not sure if you can spawn from the point cloud directly, but if not, you could use a Replicate3D to put a tiny plane (Shape3D) on each point, then use that result as the source.

However, you won't have any control over where exactly particles will appear or when—it will be at the whim of the random number generator.

I remember this tutorial by Simon Ubsdell in which he controlled the position each particle according to it's individual I.D.using a pCustom tool. Whether there is a non laborious way of converting 3D track data to luminance values or connecting each individual particle to 3D track positions, I don't know I'm a relative beginner and have more questions than answers.
