So, I made this astronaut in blender, I named her Myrtle. And I followed this really good YouTube tutorial for making an armature that deforms in reaction to physics like gravity as well as deforming the mesh. The armatures work wonderfully, actually perfectly. My main issue currently is that I can't get the air hose to collide with the astronaut's arm and body, it just passes straight through it.
It looks like this before I press play in blender: 
Then when I press play it falls down and straight through the arm and into the body: 
I'm not sure how to set up collisions or if because I added gravity to my armature for the air hose if I could even do so, if anyone is wondering what tutorial I followed I followed this YouTube tutorial: https://youtu.be/c11l2o5uCQs
I can't figure out how to make the hose less flexible either, I want it to merely react to gravity and sway when the character walks runs etc. But it actually is too string like when I add cloth physics to it.
