smooth modifier, sofa 2-3 characters
in New Users
Can I add multiple objects to a smooth modifier? I tried parent the characters, but it doesn't seem to work or am I doing something wrong... because rendering the scene 2-3 times and compositing is time-consuming...

You can't have multiple separate objects collide with the same item. A work around that I have seen is to pose the characters and export them all as a single .obj file, then import that into the scene and set the collision to the imported .obj.
This video shows how you can do that. https://youtu.be/yDmF7NDAr2Q?si=2zPoxKhiFsl_8LxU
It would be quicker than rendering 3 versions of the scene and then compositing them.
