on c4d and after effects there's some plugins that can speed up your work and save you alot of time (for example align stuff, lighting/studios/hdri/materials presets, etc) and there's some others that do unique things (turbulencefd, hot4d/ozean, greebler, ivygrower, kurulumun, reeper x, supertracer, thrausi, xparticles 2, etc)>>510078>>510108
here a few very useful: gsg light kit pro (presets library for lights setup, hdri, etc.), cs tools (free pack with some presets), nitro blast (breaking stuff), drop to floor + align anchor point (forgot the name), x particles, vray/or/octane, turbulencefd (smoke/fire), maybe magicslowmotion, ToolBox (free), motionWorks movietype, also check other plugins by gsg and pixellab. also there's people on youtube that upload free .lib4d with materials (c4d library) eg. SmokyCrasher, Rainy 3K, Markoarts, Droid Packs, Project4D, etc.
