Building a collider object

…Let's set up a piece of geometry that will function as a collider in our objects.…We're going to position it where the bridge is in our scene,…this way the flag has something to interact with when it falls.…I'm going to get out of the camera view here and turn off Background Object.…And just like when we made the belt, I will make a…new cube and parent it to the flag, zero out to PSR.…All this does is just get it into the right position.…So then I'll take it back out.…

We'll call this bridge GO.…Hit C on my keyboard to make that editable.…And we'll start getting it into position.…I'll look through the camera to do that.…Turn the background back on.…Now in order for this to be snapped and aligned appropriately, what we should…do is we'll right-click on the bridge GO, go to Cinema 4D tags > Display.…And we're going to use our lines.…Now, from this view, it's tough to tell,…but we are moving this object from the middle.…

The axis right now is still set to the middle.…What we should do is get out of this camera view.…
