Thank you. I did set 15k iterations at the beginning but i stopped at around 5k-6k iterations. I thought it was decent enough.
and if someone is interested to do this scene. The assets are
Environment: "Haven Park"
Hair: "Dark Ponytail Hair for Genesis 3 Female and 8 Female(s)"
Top Suit: "Fads Sports Bra for Genesis 3 Female(s)"
Pants: "dForce Tek Athletic Apparel for Genesis 3 and 8 Female(s)"
Shoes: I didnt have same asset with the original so i used a random one.
Watch: I didnt use but its "Let's Workout for Genesis 3 Female(s)"
Thanks the Sherlock
Alley_Cat for helping to find assets.
