    How Do You Roll Rocks Down A Hill

    I'm thinking that this is something easy that I'm missing, but maybe not. So, how do you get a few rocks to roll down a hill?

    Are they inside your physics bubble? If so, just enable the physics on them, and they'll roll. You can push them harder by using area effectors. If its outside the physics bubble, physics won't work and you'd have to simulate the rolling with animation, which would probably look funny. If its beyond your physics bubble, you can make the bubble bigger to accommodate your needs, as well as do some tricks to move the bubble when you need too.

    I just had a quick look on the PS4... some of the larger rocks don't allow physics (the option isn't there)... so be aware of that - the smaller rocks do however. You can also have a trigger linked to a physics event which is connected to the rock(s) so they fall/roll when you want them to.

    You can glue a directional force to a rock to force them to roll a certain way once physics get activated (ideally with a physics trigger when it's somewhere in the physics bubble to get consistent effect).

    Adjust the force amount and rock weight and the position/orientation of the directional force.

    Additionally you can change more advanced properties like Friction/Damping/Restitution/Gravity.

    Here some tutorials to explain the basics a bit better (should be the same for Fusion as it were for Evo for those)
