you might like to know that your small demo code helped me to get make cloth from object to nearly work,
`rotate object 3,90,0,45
sync rate 60
phy enable debug
phy start
phy set gravity 0,-29.4,0
make object sphere 1,1
position object 1,0,20,.5
phy make rigid body dynamic sphere 1
phy set rigid body mass 1,200
make object box 2,100,100,1
position object 2,0,0,49
phy make rigid body static box 2
make object sphere 3,5
phy make cloth from object 4,3
phy make cloth 4
phy build cloth 4
make object sphere 25, object size y(3)
phy make rigid body dynamic sphere 25
phy cloth attach rigid body 4, 25, 20.0, 0.7, 100.0
phy set rigid body mass 4,20
hide object 3
hide object 25
position camera 0,0,20,-30
point camera 0,0,0,0
`SET OBJECT WIREFRAME 25, 1
make object box 10,100,1,100
position object 10,0,-1,0
phy make rigid body static box 10
do
if spacekey()=1
phy set rigid body position 25,0,50,0
endif
phy update
sync
loop
its not 100% but it does nearly work.
