This is a blender only version a little different from the one I published for the sims4 game
Realistic textures, soft weight paint and better quality
No more clothes torn by ripper, low quality textures, morphology problems
Have more realistic clothing for better quality renders
This is not an obligation, you can continue playing with the versions compatible with the game, this is an extra that will give you higher quality in your renders and stop suffering because the clothes break for your body type
