A little help with smoothing polygons in cinema 4D

[Peardian]

See the Normal Tags next to each mesh? The second tag, next to the UV tag? Delete those. The process of converting the model to DAE from PSK unfortunately gets rid of all of the smoothing groups. Keep in mind that you'll have to delete these for every rigged model you'll want to use, even if it looks smooth, as the lighting on the model won't be affected by the new positions caused by moving bones.
