Reactor Alan McKay notes

Go Helpers/Reactor ...

Or right click on main menu/reactor ... this can be undocked ...

Create a rigid body collection

Add all items to the RB Collection ...

Each one needs to have its parameters set

Set the 2 boxes as bounding box

And the teapot and the plane as concave mesh [slower but more accurate]

Let’s make the plane unyielding so it will not move when we do our simulation.

we will give the boxes some weight, 250 and 80 kilos ... [actually, this is all in generic units] ...

teapot will be 40 kilos

To avoid problems with intersecting bodies, we can change the reactor collision tolerance to 0.5 in the utilities panel

Move all objects UP a little off the plane ...

Run a preview animation ...

Hit P to play/pause ... the left mouse rotates the entire set ...

the right mouse btn moves individual objects , you can knock them over, etc.

R = reset.

Here are the mouse tips:

Any object set to UNYIELDING can be key-framed ... let’s set the small box to move around and see what happens ...
