Here is a 3D model modeled in 3ds max, sculpted in Zbrush, and rendered in Marmoset ToolBag 3.
It took me 15~20 hours to finish it, as it was my first experience in Zbrush and Marmoset, but I did learn very useful tips for those softs.
Also, I did all of this using a great tutorial made by Alex Jerjomin on Pluralsight, available here : https://www.pluralsight.com/courses/game-environment-zbrush-3ds-max-2153
