hi. i dont know how to approach this problem efficently: i would like to apply a force (like wind) onto each face of a polygonal object. i would like the object to "burst" into pieces by putting a force in the center. unfortunately i dont know how to get each part/face of the object to behave individually to the force.
Separate faces into individual objects, turn them into rigid bodies and apply negative newton field. You might want to write a script to automate the process.
