Since this is my first Addon on the Blender Market it won't be perfect.
Please keep in mind that the addon uses blenders physic system with all its limitations.
So don't overdo it, especially if mesh is selected as the shape.

As active objects all selected objects are taken (only mesh objects).
As passive objects all objects are selected, which are selectable.
So anything that is hidden will not be affected.

It is recommended to open an isolate view with the objects to be used in the simulation.

Please feel free to send me suggestions for improvement or if you notice bugs with send me the text from the console.
