I think you just want to attach some particles in place, which is what attachments do.
To achieve this, you can just use attachments. Check out the RubberDragon sample scene, as it does what you describe here: the bottom part of the dragon is attached in place using an attachment component, so that you can drag to deform it, but it doesn't move around.
Yes! I have used the attachments on the particles on the bottom of the objects! That worked very well! Really appreciate it!
