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.
