Here are some ZBrush sculpts I did for a physically-based muscle system simulation.
The project was a great experience - I had the pleasure to work with the creature team led by James Jacobs and Lonnie Kraatz.
One interesting aspect of this study was looking at anatomy - not only from what affects the surface of the model - but also in terms of the volumes of the deeper muscles, and how they are all put together.
This approach really affects the end result of the simulation.
Dynamesh was a great feature in this workflow - after the blocking pass of these muscles, I could sculpt lots of the muscles worrying primarily about the overall volume, and then later on I could just subtract one mesh from another, removing the intersections. Then, once we had the muscles at a stage that could be decent enough to put through a first test, we just ZRemeshed everything.
For the skin (the horse model), I just started out with ZSpheres and kept sculpting and ZRemeshing every time the sculpt advanced. This allows the creature team to be testing the skin-over-the-muscle simulation while the model is still in-progress.
On the images I posted, the model is a little bit further along than the simulation shown in the video. It is, in a way, still a work-in-progress.
Special thanks to Eliot Goldfinger, whose "Animal Anatomy for Artists" was invaluable.
Love anatomy, and love this! Great job there! And thanks for stopping by my wip thread before. I watched The Maze Runner some time ago and the graphics was what made the movie. Awesome that you got to work on the Grievers, and well sculpted! Every time they appeared my legs wanted to twitch as to start running!
rasmusW - Thanks, and glad if the workflow info was useful!
Zachris, that's awesome you enjoyed the movie, it was a really fun opportunity to get to sculpt the Grievers and see them in action later.
I'm an anatomy fan also - really enjoyed your thread, and the detail of your work.
Thanks so much for your kind comments.
I really appreciate it!
arume123; Thank you!
rodras; Thanks also All the muscle work was done using tools written by james jacobs and the creature team, so it's not a software package - it's been written in-house.
If you want to know more about this kind of approach, try searching up these guy's names, and there should be some information on the web.
paulhpaulino; Thanks so much! And thanks for checking out Artstation too. So lucky to have had this team together.
Andre_Lopes; thanks also, so much. Glad if you think it's hitting the bar.
This is a WIP test, so it never got to realize it's full potential, I'm glad if the essence of it is coming across.
I hope that in the future I can post something more final.
