Cloth Pressure

[Spumantii]

I follow a cloth tutorial with the following steps:

 

Create a plane

Create a box just above the plane and subdivide it into many quads

Create a gravity force

assign cloth modifier to the plane and box

make the plane a collidable object

make the box a cloth with DEFAULT values

give the cloth an inflate pressure of 30 (30 what?? Another arbitrary value)

simulate

 

 

EDIT: Further test shows the thing fully inflating with a pressure of 0! Why is it inflating with a pressure of 0?

EDIT SOLVED: Apparently I'd added the cloth modifier on top of the stack and subdivided the box afterward and the cloth did not recognize the new geometry. OR the object was at the wrong scale and the inflation units were comparatively high.

Negative pressure, this is pretty cool. I was trying to figure a way to 'tuck in' the sheet. Anyone know any tricks using the cloth modifier for furniture? My pillows still need work, they look like rubber water bottles..
