Well, I don’t want to flat out steal another artist’s work, especially when the 3D market is so small in comparison to other markets, and also, the sculpting if it’s manual wouldn’t accommodate other different types of objects in a timely manner too, as a practical workflow skill, even though sculpting itself is still a good skill to have.
This is a good video of what I’m talking about, and why I think a physics-based answer would speed up my workflow: https://www.youtube.com/shorts/uLiFrMMFTU0 as well as other peoples’.
But, the object here in this cardboard example isn’t exactly a pillow, it’s more like a thin plastic material, so a different kind of physics setting would be needed than the pillow I assume.
