Moonlight Greatsword

Hi all! I finally got my hands on Marmoset 4 and learned about the new ray-trace function.
Moonlight Greatsword is my all-time favorite weapon, I made this one with my own interpretations based on all the other Moonlight Greatsword in From Software games.
I'm really impressed with how the transparent material turned out to be, the problem is it generates lots of noise when I'm rendering the animation. If anyone can tell me how to fix that it will be great : )
