Turning a Decor Object Pillow into a Crib for Infants

It would be helpful to share your files so someone can look at them for you. The crib and the bassinet contain a rig that corresponds to parts of the baby's body and if you look in the slot section in Studio you'll see a bunch of slots that also correspond to the baby's body. You could edit the rig and the slots but because it involves animation you may run into trouble. I think the easiest thing would be to leave the slots and rig alone and just swap out the meshes and textures with your own. This means that you'll need to import the EA mesh you're replacing into Blender and then import your custom mesh. Make sure your custom mesh is the same height and roughly the same width and length as the EA mesh. You'll at least want the width and length of your mesh to be able to accommodate the rig and the slots if that makes sense. You don't want parts of the rig to be outside of the mesh; if the rig was outside of the mesh I'm pretty sure the result would be a floating baby. And if the slots and rig are moved closer to the floor you may have issues with the sim's arms stretching when the sim picks up the baby or other weird animation glitches. I mean, I don't know for sure but this is what I think would happen. So, yeah, you could try moving the rig closer to the floor in Blender and editing the slots' locations in Studio but I'd bet my life you'd have problems with animations.

I'm not good with animations. Maybe someone here has more experience with this and can help. It would also be a good idea to share your files. That way, you can get personalized help.
