The main way to adjust the waiting is to interactively paint them,
00:08
which is much easier and a lot quicker
00:11
to open the paint whites tool,
00:13
just go to the rigging shelf and click on this button here.
00:20
So here we have a list of all the joints that are affecting this model.
00:24
If you select one, you'll see a gray scale area appear.
00:28
This is that joint's area of influence.
00:32
If we scroll down, we will see those twist joints we added manually.
00:36
You will also see the padlock next to them is yellow indicating these are locked,
00:41
which is fine.
00:42
If you remember,
00:43
we locked the weights when we added these to
00:45
stop them influencing the rest of the model's weights.
00:48
So we just need to go through and unlock these. Now,
00:52
just click on the icon to do this
00:55
and let's find the rest. While we are here
00:59
at the moment, the joints are sorted according to the hierarchy,
01:03
but you can change this up here.
01:07
So we can see them alphabetically
01:10
hierarchy
01:13
or just flat.
01:16
What we can also do is filter the list.
01:19
So let's say we just wanted to work on the twist joints
01:23
we can input twist here and it will just show us the joints with twist in the name
01:30
down here. We can choose what mode we want to work in.
01:34
Paint
01:35
select
01:36
or paint select.
01:38
I rarely use anything but paint here.
01:45
Next, we have the main area where the paint tools are.
01:48
First is the paint operation area.
01:50
So you can dictate how you want the strokes to affect the weights.
01:55
Replace will simply swap the current weight value with the one you have specified.
02:00
Add will gradually build up an area.
02:03
So you can continually add a value to it.
02:06
Scale will simply scale the values. But again, I never really use this
02:11
finally smooth,
02:13
will gently blend the weights for you to soften and smooth an area out.
02:18
Next, you have your brush types which range from soft to hard
02:25
normalize weights. We discussed this before,
02:28
but there are very similar options here.
02:31
Next, we have the opacity and value sliders which work hand in hand with each other.
02:37
Opacity is basically a percentage of the value slider.
02:42
So value is the main weight value
02:44
and opacity will paint either all or part of that.
02:48
If value is set to 0.5
02:51
opacity will never be able to paint above that value.
02:55
This works well as it allows you to gradually adjust the weights,
02:60
it gives you more control.
03:03
Let me show you
03:04
a quick tip is you can also select which joint to work on in the main view,
03:10
just right click on the joint and go to select influence.
03:14
So with opacity and value both set to one,
03:17
we get solid white.
03:20
So these vertices are being influenced by the Pelvis joint 100%.
03:25
If I reduce the opacity,
03:30
you see we can instead gradually add those weight values.
03:35
If I instead set opacity to one
03:38
and then drop value,
03:42
no matter how much we paint, we won't be able to go over
03:46
the value amount.
03:48
We can still drop the opacity and gradually add the weights,
03:52
but they won't go over this value of 0.1456.
03:57
So those are the main painting tools.
04:00
Oh yes. One other option is flood.
04:02
This will simply fill the whole model with that value.
04:08
So now the model is influenced fully by the Pelvis joint
04:12
down here. We can control how the influence is represented.
04:16
Personally, I prefer to work with just gray scale,
04:19
but you can enable color feedback if that works best for you
04:23
with. This enabled red is the higher weight value.
04:28
Here. We have options to adjust the paint stroke.
04:32
You can also use a graphics tablet to control the opacity.
04:35
If you want a more interactive painting experience,
04:38
also you have various display options here.
04:42
So if we didn't want to see the joints through the model, we could disable this.
04:48
I think that's the main options covered the ones I use. Anyway,
04:52
obviously, there's so much more to this tool.
04:54
But for this project, those options are fine.
04:58
Before we end,
04:59
I also want to show you that you don't always
05:01
have to paint the weights on the whole model.
05:04
Let's select these vertices
05:06
here.
05:07
Now, if I go back to the paint whites tool
05:11
with opacity and value set to one.
05:14
If I paint, now the area I am affecting is restricted to just those vertices.
05:20
You see I can paint up here but nothing happens.
05:24
I can also use flood
05:26
and it will just update the selection.
05:30
This can be really useful for blocking in weights quickly
05:33
or when you are focusing on just one area.
