Been making this revolver for a while now, and finally feel decently happy with it. Enough atleast to post it xD.
It's a snubnosed Italian Revolver called a Chiappa Rhino 200D.
Everything is Rendered in Marmoset Toolbag 4 using Ray tracing.
Thank you to everyone that has helped me with feedback, and thank you to everyone that has taken their time to show me how to approach things in both theory and practice!
