The Zbrush 2021 dynamics system offers great possibilities to create different types of cloth but there is some learning curve to it. With this video I hope to give you a good introduction, that shows you what every attribute does and at the end I show how you can apply it to the cloth simulation of a puffy jacket and red dress, covering some of the cloth brushes as well.
I will also touch upon some other new features of Zbrush 2021 like the thickness attribute in the dynamic subdivision tab.
The button insert brush I used(itâ€™s free and also comes with stitch and seam brushes):
1:30 Dynamic SubD and thickness
2:15 Collision Volume and Recalc
3:00 Simulation iteration
4:03 Simulation Strength
5:13 On masked
6:13 On brushed
7:28 ClothHook brush
10:00 Floor collision
10:22 Allow Shrink
11:25 Allow Expand
12:00 Gravity strength
12:48 Set direction
14:10 Collision volume resolution and inflate
15:30 Max simulation points
17:40 Puffy jacket
23:18 red dress
For the clothing I created some polygroups for areas I want to mask out, these are the seams of the Jacket. Then I run multiple passes of Simulations using Inflate, deflate, and Expand options in XZ, XYZ, and sometimes just Y-axis to achieve certain looks. I usually store morph targets to then use the morph slider to adjust the strength of the effect or to switch the morph target to then grab the morph brush and add specific details that I liked.
Finally, I use a lot of the new Cloth Brushes from Zbrush 2021. Here’s a small list of the brushes I like:
ClothHook: to create larger-scale effects and to move the cloth in certain directions
ClothPinch: Creates nice Pinched clothing like ruffles but it looks rather uniform and pushes the mesh in quite a bit. So that might require some clean up.
ClothInflate: Works just like the inflate in the dynamics simulation, inflating the mesh.
ClothNudge: Very nice to create smaller-scale surface details like memory folds. I used that brush to break up some of the uniform looks of the ClothPinch brush.
ClothPull: Nice to create directional wrinkles, but can be intense.
