Thx, The left is what I load from genesis 8 female essential, and the right is G3F essential, both without any morphs, so I am supposing that My G8f base model needs to reinstall.
But still, if those did not work, I may need to re-form G8F base model by other methods.
Also, the bimbo feeling comes from the face that looks like smirking, on the left of my pic it shows a smirking by the lips. by the side view it looks more caucasian female with lewd face, rather than a default raceless face ought to be.
