Easy! Sorry i did'nt remeber this post!
To set material effect for pushing!
1. Action: NewtonWoodEnitity
2. Mass: 10.000
3. Linear_drag: 0.100
4. Angular_drag_x: 0.100
5. Angular_drag_y: 0.100
6. Angular_drag_z: 0.100
7. Set flags to Start_active!
8. Update enitities, and here you go !
You can push Signs and other models!
Wait! with material effect without pushing any models i am trying to FIND how does it work!
