Hello everyone.

And in this video we are going to take a look at collections.

The collection panel right here allows you to choose collections that will interact with the fluid.

So for example if I have multiple floor objects in different collections I can select one of those collections

and that will only be the flow object.

Same thing goes with the factors down here.

So if I was to select one of these collections it will only use those collisions in that collection.

So let's go ahead and test that out.

I'm going to select this object here which has a collision effector.

I'm going to press the MP and move it to layer 2 or collection 2.

Now if I select my domain and scroll down I'm going to select the effector and I'm going to limit the

vector to collection one.

This effector is in collection too.

So now this won't affect the simulation.

Now I can bake this data and we can see down here it's starting to bake.

And now if I posit right about there and restart the animation and play this we can see it goes right

through the collision even though this does have a collision modifier applied to it.

It's going right through because we limited the collections down here.

Now if I free this data and select collection 2 which has the collision I can go ahead and bake this

data one more time and then I can pause right about there and you can see already that it is interacting

with the collision object because we apply it to that collection to the effector restart and play this

and we can see it's working correctly just like that.

This works for both collisions and low objects as you can see right here.
