blender can't do the painting. yet. and i doubt it will be as intuitive as carrara's. 3d painting is still a feature that very few apps do well, only carrara and bodypaint do their job well imo. blacksmith3d paintSuite feels awkward and is unprecise, tattoo has been canceled. the last remaining app i know that allows 3d painting is 3d coat, coat3d ort whatever they renamed it. people will probably love coat3d more, but i never got it in my brain.
