Hi Ferdinand. Thank you for the thorough response. Apologies for the ambiguity on my part.

For a test project I wanted to fetch star coordinates (for ~100K–1M+ stars) and their brightness values. Then instance Redshift spheres onto them with a material where the brightness of each point is piped into the material's emission.

This was a test project to get started with python. I also wanted to see if c4d has a way of working with points and attributes. I don't think the real-world (galaxy?) data is available, but ideally each star would also have a radius, which would drive the sphere scales/sizes.

I'm familiar with cloner/effector/field setups, but I was looking for a programatic approach. I don't know how to pass specific values to each point (brightness in this case) and then to clones with effectors/fields.

I have a list of thousands of points where I'd like to add a brightness value to each of them to drive material emission and instance spheres onto the points. I've been reading posts like this and this--how would you approach this type of task in python?

I can setup a cloner object in multi instance mode but I'm not clear if it's possible to pass the brightness values to the (invisible) motagdata tag... Would a python generator be a better way to go?
