All language subtitles for 10. Field Weights

We have one more panel to go through in the domain settings.

We have the field awaits.

This allows us to change how the simulation reacts to force fields and also gravity.

In this simulation I've added in a force field right here and to do this you compress shift day and

go underneath forcefield and you will see a lot of different forest fields that you can add the wind

force field will just give a constant wind along the side that you point it to and you can also give

it a strength.

I set mine to twenty five and then the flow is set to 1.

Now if we go back over to our domain settings we can take a look at what these do if I played my simulation

we can see the wind is pushing the simulation along this sign until it crashes into the side of the

domain.

Now currently it's at 100 percent and I can tweak how strong this force field is by changing the wind

force field down here.

So if I was to set this all the way down to zero and bake in the simulation this wind force field will

no longer affect the simulation because we set it to zero down here.

We also have an all option here so if we have multiple force fields this controls everything and if

we turn that all the way down no force fields will affect the simulation.

Now we also have the gravity option right here.

Now this does not affect the simulation.

If I turn this all the way down and we bake in the data let's go ahead and free that bake and then click

on Big Data.

We'll posit right about there.

We can see this does not affect the gravity the fluid is still flowing down.

Now if we wanted to affect the gravity what we would need to do is go over to this panel right here

the scene panel and then in the gravity section turn the z value down to zero.

Now this will affect the gravity.

So now if we bake this in we can see it's starting to work down there will pause it right there and

you can see the fluid is staying in midair because there is no gravity in the scene.

So this gravity value does not do anything.

If you want to change gravity you're going to need to do that in this gravity panel right here.

I'm going to go ahead and set that back to negative nine point eight.

That is the default setting and now it can keep going in this field waits panel.

Now the last thing that we'll talk about is the effector collections.

This allows you to select collections with force fields and limit those.

So for example if you were to have multiple force fields and you only want some of those force fields

to affect the simulation you will put that in right here.

So for example I'm going to select this force field and move it down to collection to then I'm going

to press shift day and add in a nether wind force field a rotated up like this.

I'll place it on the side and give it a strength of 15.

So now we have one forcefield in collection one and another force field and collection too.

I'm going to select my domain and I only want the forcefield in collection one to affect the simulation.

So what I'm going to do is select collection one over here.

So now this force field will no longer affect the simulation.

The only one that will be affecting it is this force field.

Now if I select my domain Free the Data and bake it one more time.

And now if we play our simulation this is not working and I think the reason for that is because I forgot

to turn up the all option right here.

So we're gonna go ahead and turn that back all the way up to 1 and the wind all the way up to 1 2 it

actually affects the simulation and we'll also turn up gravity and we will free this data and bake it

back in because I am dumb and forgot to change that and now that we have all of our settings correct

we can go ahead and play our simulation and you can see this is working properly this forcefield no

longer has an effect on the simulation.

The only one that has an effect is this one right here because it is in collection one and we set up

that collection in the field weights affect our collection.

So there you go.

That is all of the settings in the domain.

Thank you for watching.

And in the next video we will take a look at flow objects inflows and outflows and all that.
