11
00:00:26,080 --> 00:00:29,020
And as you might expect Wind Direction
12
00:00:29,020 --> 00:00:31,080
this is kind of telling the Force of Wind
13
00:00:31,080 --> 00:00:35,050
how to affect our cloth and from what direction.
14
00:00:35,050 --> 00:00:37,030
So, X would be
15
00:00:37,030 --> 00:00:39,060
how much Force is exhibited from left to right
16
00:00:39,060 --> 00:00:40,060
and right now there's zero.
17
00:00:40,060 --> 00:00:43,030
So if we set this to something like 120
18
00:00:43,030 --> 00:00:47,020
and turn up our Wind Strength from zero to one
19
00:00:47,020 --> 00:00:49,050
you'll notice that there's a little gentle breeze there
20
00:00:49,050 --> 00:00:52,090
going from left to right and that's a positive value.
21
00:00:52,090 --> 00:00:55,090
If we set it to -120
22
00:00:55,090 --> 00:00:59,040
the wind's going to blow from right to left.
23
00:00:59,040 --> 00:01:01,010
And likewise for all these other values here.
24
00:01:01,010 --> 00:01:04,040
If we set this to zero and wanted to increase the Direction
25
00:01:04,040 --> 00:01:06,040
that the Wind is coming up from underneath us
26
00:01:06,040 --> 00:01:11,020
and pushing up in Y, we would make that a positive value.
27
00:01:11,020 --> 00:01:13,080
Maybe 300 and pump up this Wind Strength
28
00:01:13,080 --> 00:01:16,080
to maybe two or three, let's try three.
29
00:01:16,080 --> 00:01:21,080
Now we're getting some Wind from below us, pushing it up.
30
00:01:21,080 --> 00:01:24,070
And likewise if we see -300,
31
00:01:24,070 --> 00:01:30,030
now there's Wind coming from up above.
32
00:01:30,030 --> 00:01:31,060
Let's bring that down to zero.
33
00:01:31,060 --> 00:01:33,090
If we wanted Wind pushing away from us
34
00:01:33,090 --> 00:01:37,000
that's in positive Z, away from the camera,
35
00:01:37,000 --> 00:01:38,030
so that would be...
36
00:01:38,030 --> 00:01:40,000
You know even there, you're seeing it there
37
00:01:40,000 --> 00:01:41,090
with the Wind Strength set to three so,
38
00:01:41,090 --> 00:01:44,010
switch over to our perspective view
39
00:01:44,010 --> 00:01:47,070
and we'll see that the Wind is pushing in Z space,
40
00:01:47,070 --> 00:01:49,010
away from us.
41
00:01:49,010 --> 00:01:57,030
And -200 pushes the Wind toward us.
42
00:01:57,030 --> 00:01:59,030
So let's come back here to our Front view,
43
00:01:59,030 --> 00:02:01,000
hitting F4 on our keyboard.
44
00:02:01,000 --> 00:02:02,080
And so that's what Wind Strength is
45
00:02:02,080 --> 00:02:04,000
it's just how much contribution
46
00:02:04,000 --> 00:02:06,040
and what direction do you want this thing to go.
47
00:02:06,040 --> 00:02:09,030
You'll notice here under Turbulence Strength
48
00:02:09,030 --> 00:02:12,050
we're set down to .2 and so this Turbulence is
49
00:02:12,050 --> 00:02:16,010
kind of with the Cloth engine telling how much Wind,
50
00:02:16,010 --> 00:02:18,030
the gusts of Wind, these little bursts of Wind
51
00:02:18,030 --> 00:02:20,040
that happen in the real world, how much of that
52
00:02:20,040 --> 00:02:23,020
do you want to have contribute to the simulation.
53
00:02:23,020 --> 00:02:26,010
So, right now the Strength is set down to .2,
54
00:02:26,010 --> 00:02:28,070
turn this up a little bit to 60
55
00:02:28,070 --> 00:02:32,030
and we'll turn down the Wind Strength down to one.
56
00:02:32,030 --> 00:02:35,020
And now, you can see that there's strong gusts of Wind here.
57
00:02:35,020 --> 00:02:39,050
Oops, that's at the 12, let's bring that back down to two,
58
00:02:39,050 --> 00:02:43,080
we'll rewind the simulation here.
59
00:02:43,080 --> 00:02:46,020
So the Wind Direction, that's kicking in,
60
00:02:46,020 --> 00:02:48,000
it's blowing from left to right.
61
00:02:48,000 --> 00:02:50,020
And our Turbulence Strength is set to .2
62
00:02:50,020 --> 00:02:51,090
so we're getting a little bit of gust in there,
63
00:02:51,090 --> 00:02:54,070
so it's pretty subtle.
64
00:02:54,070 --> 00:02:56,060
But as we drive this up further,
65
00:02:56,060 --> 00:02:58,010
so say something like two,
66
00:02:58,010 --> 00:03:01,070
you'll get stronger gusts of Wind pushing up on that cloth,
67
00:03:01,070 --> 00:03:03,080
as you can see there.
68
00:03:03,080 --> 00:03:05,020
And the Turbulence Speed,
69
00:03:05,020 --> 00:03:08,060
that just dictates how fast you want those gusts to come.
70
00:03:08,060 --> 00:03:10,030
So if we bump this up to like four
71
00:03:10,030 --> 00:03:12,000
you'll get more frequent gusts of Wind
72
00:03:12,000 --> 00:03:13,080
pushing on that cloth.
73
00:03:13,080 --> 00:03:15,070
I'm going to talk about the Wind Impact
74
00:03:15,070 --> 00:03:16,090
because that's pretty important.
75
00:03:16,090 --> 00:03:18,020
Right now it's set to 100
76
00:03:18,020 --> 00:03:20,080
and you'll see that all this Wind simulation that's going on
77
00:03:20,080 --> 00:03:24,030
and affecting our cloth is set to a 1
