Hi, am experienced on C4D +hundreds proyects and +12 years experience.
Most of the reference images you presented are using xparticles, xpresso, tracer, lens flares, enviroment fog and atom arrays, except xxx3300 I think they used some particles on AfterEffects too.
I would like to know the animation script if exist, the animation or animations lenght, the final resolution and output format you would like the delivery, and when you would like to get final results.
Feel free to chat any time to discuss details and how is my proposed workflow and fees for your specific project.
Cheers
Jacky
