If set prop to Rigid Body, set Convex Hull/Self Mesh to Bound Type, the soft cloth will fall through the prop when executing physics simulation
STEPS TO REPRODUCE 1. Launch iClone 6, apply prop Ball_001 2. Apply soft cloth prop Flag 1, then pick Flag 1, press E on keyboard, drape it on top of Ball_001 3. Pick Ball_001, navigate to Modify > Physics, check the box for Activate Physics, then select Rigid Body, click “Static” button 4. Go to Bounding section, set “Convex Hull” to “Bound Type” 5. Click to play
ACTUAL RESULT The soft cloth fell through the ball
EXPECTED RESULT Cover the top of the ball with the soft cloth
NOTE Same issue also reproduced when selecting “Self Mesh” as Bound Type
