Particle system from selected object How do I create a particle system from an imported stl model and use that to fill the shell of another model? As you can see below, I want to fill the model to the right. There are two issues I am having. 1) The body is currently emitting the mini figurines rather that the internally contained collisions I was expecting. 2) A displaced modifier was applied to prevent the particles from moving beyond the skin, but if I could just set the collision boundary to the skin itself, that would be best. I read that applied modifiers are permanent, so I may need to redo this particle system on the original stl. Thank you!


(11/9/20) Tried Vertex paint mode and selecting the body under the Vertex Group --&gt; Desnity, but it still had the same effect. I think the problem also is that internal face or area is not the source of the emitter. However, I found a tutorial here that shows how to fill a container by funneling the smaller objects via implemented physics engine. Will see if that works!
I believe what you're looking for is the 'hair' particles system, if you want another object to cover the main object. When you add a particle system to an object, one of the first options should be to choose from Emission and Hair, switch it to hair. I'd recommend watching some tutorials for the same. If this is not what you were looking for, please reply.
