I have a plane as collision object and a house as particle generator. I'm dropping my particles. I have tweaked some settings so that they fall in some natural way, but they just bounce like a ball and disappear.
It should look as is they are thrown from the top and fall down in a natural way.
How can I achieve a result like the image below?
Result i need few 20 particles (red house)

Here's the .blend file:
