The other cool thing that you can do with guides is you can switch the velocity source over to an effector

and use an object instead of a domain.

So to demonstrate this I'm gonna press ship day and add in a monkey head of right here I'll drag it

below the domain.

And now we're going to animate this on frame 1.

I'm going to hit I and go location rotation then at frame 30 I'm going to press G and C and drag it

through the domain hit I and go location rotation once again.

Now if we go over to the physics tab we can enable fluid set the type over to effector and then for

the effector type we can select guide.

Here we have a couple different settings is planned are we've talked about this before.

If you're using a plane you are going to want to turn this on the surface thickness.

This is the amount of thickness around the object that will be considered as a guide and for this example

I'm going to bring this up to a value of point five.

So instead of just being at the monkey head the amount the surface around it will also affect the guiding

as well.

So it'll probably be around here and then the velocity factor.

This also is a velocity factor that will move the fluid a lot quicker.

So if you want slower moving velocities you will turn this down the guide mode it takes the velocity

of your monkey head and the velocity that you said here and then does a little bit of math to figure

out exactly what it should do.

So for example if this is set to override it's going to override the velocity of this monkey head and

just use this value here.

If this is set to average it's going to average out the velocity of the monkey head and the velocity

that you put here and just use an average for this example.

I'm gonna set it to average.

And now back over in the domain settings I can scroll down to the guides.

Here we have a new button called Bait guides.

We did not have that we knew when we were using the domain but now since we are using an effector we

do need to make the guides before we bake in the liquid up here.

Keep in mind before you bake in the guides you also need to set the resolution because once you bake

in the guides this will be great out and you won't be able to change it.

I'm going to leave the default settings and I'm going to select bake guides.

You can see it went very fast down there and now we can go over to the settings up top and we can see

the resolution is great out.

We need to select bake data right here for this to work since I am using a resolution of 32.

This is going pretty fast.

So now it's resort to simulation and play we can see this is what happened.

So since the monkey head is moving pretty slow and the resolution for the guide is also set to 1 and

it's averaging it out it's not doing a lot of motion as you can see there.

So if we wanted this to be a lot faster what we can do is scroll down here.

Free the guides so we can change some of the settings.

I'm going to set the velocity factor up a little bit.

Let's go with a value of six and we'll see how that looks.

We'll bake the data we'll scroll up to the settings and bake the data up here as well.

With that done baking we will restart and play this and we can see there is a lot more velocity now

since we set the velocity factor up down here.

So if you want faster moving fluid you will set the velocity factor here and you will also set the velocity

factor over here as well.

We'll restart this you can view that one more time and that's basically what it does it just add some

velocity using an object you can create some very interesting results using this.
