آموزش ترنسپورت زیبراش ZBrush Posing models with Transpose pt. 2

آموزش ZBrush به صورت مقدماتی  و مدلسازی پیشرفته به زبان فارسی

وقتی مجسمه یک شکل یا چیزی شبیه این دست را ایجاد کردید اینجا و

  شما آماده هستیم که مدل را بسازیم، شما می خواهید از ابزار Transpose استفاده کنید.

  ابزار Transpose همانطور که از نامش پیداست طراحی شده است تا به شما کمک کند مدل های خود را مطرح کنید.

 من از مدل handpose استفاده می کنم و این برای کاربران حق بیمه وجود دارد و زمانی است

  من این مدل را بارگیری میکنم، اگر نگاهی به پالت Sub Tool بیاندازید، من واقعا دارم

  تکراری از این مدل هر یک از این تکرارها مطرح شده است و من

 این ها را با استفاده از ابزار Transpose ساخته اند. بنابراین این واقعا خوب است

  تمرین ورزش به دلیل اینکه دست دادن می تواند روی حیله و تزویر باشد.

 بنابراین من فقط به طور پیش فرض من مطرح شده در اینجا، و من آن را بر روی بوم کشیده شده و

  من در حالت ویرایش هستم و در حال حاضر من دکمه قرعه کشی فعال شده است. وقتی من هستم

9 دکمه قرعه کشی فعال شده است، به یاد داشته باشید که بدان معنی است که اگر من در بالای صفحه قرعه کشی کنم

  مدل، من در واقع قصد دارم مدل را با استفاده از Brush Sculpting Brush تغییر دهم.

  برای فعال کردن ابزار Transpose، من می خواهم به Move تغییر دهم. بنابراین من ویرایش کردم و من

  حرکت فعال شده است. من همچنین می خواهم Symmetry Activate را غیرفعال کنم، بنابراین هیچ مشکلی وجود ندارد

  تقارن در مدل ما ابزار Transpose داریم. این سه مورد آشنا هستند

دایره با خط عمل در مرکز. به یاد داشته باشید که می توانم تغییر دهم

  موقعیت ابزار خود را با کشیدن بر روی این حلقه ها. بنابراین این بیرونی

 دایره ها برای تغییر محل ابزار و حلقه های داخلی در واقع تغییر می کنند

  مدل خود را بر اساس موقعیت ابزار.

  بنابراین حالت Move را فعال کرده ام و فقط می توانم بر روی مدل کلیک کنم و از آن خارج شویم

  ابزار Transpose و سپس وقتی روی دایره مرکزی کلیک میکنم، من این شی را می برم.

  در حال حاضر تفاوت بین این و این چیست؟ خوب، این کمی آسان است

  برای اینکه بفهمم آیا بعضی از ابزارهای زیر را میبینم قابل دیدن است. اگر فقط این را بکشم، من هستم

00:01:58 فقط نگاه کردن به تمام شیء، اما اگر در مرکز اینجا با کشیدن

00:02:03 حرکت فعال شده، در حقیقت حرکت شیء است. بنابراین من به این تغییر کرده ام

00:02:10 شی در ارتباط با ابزار زیر، با کشیدن در مرکز. من قصد دارم

00:02:15 مخفی کردن این، بنابراین ما می توانیم روی این تمرکز کنیم.

00:02:27  Now if I drag on the end with Move  activated, I actually start to stretch the

00:02:32  model around. The way you can think  of it is, I'm moving these parts of the

00:02:36  model that are closest to this end of  the tool and this end of the tool is the pivot.

00:02:43  So if I drag over here, I get the  opposite. The elbow of the upper forearm

00:02:49  moves more than the area around the  knuckle here, I can see that the knuckle is

00:02:54  not moving at all. When I switch to  Rotate mode and I have the subtool visible

00:03:03  as well, so you can see, but if I  start to rotate, I'm rotating the object in

00:03:08  relation to the subtool.

00:03:10  And when it comes to posing, Rotate is  probably what you are going to be using

00:03:15  the most, and I will show you why. Well,  when you think about it, think about

00:03:18  your hands. The tip of your finger  rotates on the pivot of that rotation is

00:03:23  your knuckle.

00:03:25  So in other words if I were to use the  Transpose tool, this would be the pivot

00:03:30  and this would be where it rotates.

00:03:32  Now of course if I drag on this, I'm  rotating the entire object. So how do I

00:03:37  rotate just the finger?

00:03:40  Let's hide this for a second. The key  to that is Masking. If I mask the entire

00:03:46  object, let's mass that, and mass the  other fingers, let's zoom in a little

00:03:52  bit. Here's the Scale button and mask  right here, switch to the Side View,

00:03:59  start rotating, now I'm  rotating just that finger.

00:04:06  The problem with that of course is  that mask was very tricky to create; I had

00:04:10  the mask once, and then these fingers  and then this part of the finger. The

00:04:13  Transpose tool has its own masking feature.

00:04:16  We can also create a mask using the  Transpose tool itself. So I'm going to

00:04:21  expand the Masking palette, press  Clear. Normally when I have the Transpose

00:04:26  tool activated, and I drag on the  surface, I'm drawing out a new version of the

00:04:31  tool. But I'm going to hold the Ctrl  key and drag on the surface, and now I'm

00:04:36  getting a very special type of mask  that follows the topology of the model. The

00:04:41  topology is just basically the  arrangement of polygons on the model.

00:04:45  So if you watch as I drag it out here,  you can mask everything but thumb very,

00:04:54  very quickly. You will also notice  that when I let go, the mask that has been

00:04:59  created is automatically blurred. So  topology masks are always blurred when you

00:05:04  draw them. If you decide that you want  to sharp edge to it, you can always go

00:05:08  and press Sharpen Mask.

00:05:10  When I'm doing a finger, it might  actually be easier to start by holding the

00:05:17  Ctrl key, dragging on the finger I'm  masking the part that I want to change.

00:05:21  I'm going to let go and then I'm going  to invert the mask. That's a lot easier

00:05:27  to masking the entire arm,  everything but the finger.

00:05:29  Now that I have the tip of the finger  unmasked, when I have Rotate activated,

00:05:34  I'm going to click on here and drag out  to the tip of the finger, and now let's

00:05:41  reposition this, so it's little bit  closer to the knuckle here, and now when I

00:05:45  drag on here, I get a fairly decent finger bend.

00:05:53  Let's do that again. I'm going to  clear the mask and I'm going to click over

00:06:00  here just to get rid of the tool, and  I'm going to hold the Ctrl key and drag

00:06:06  very carefully, along the surface to  just the finger. Reselect it, and let go

00:06:13  and I'm going to invert the mask.

00:06:15  Now I'm going to drag from the knuckle  towards the tip of the finger, I have

00:06:22  Rotate on, and now I'm just going to  drag on this circle to rotate the finger.

00:06:29  I just had to remember that the  opposite end of the tools, the pivot, so I

00:06:34  could drag right here if I wanted to break  the finger, and then this becomes the pivot.

00:06:40  In this case this might be a good place  to sharpen the mask a little bit. There

00:06:46  we go, now we get a nicer  bend there in the finger.

00:06:53  I can switch to this view, drag out  another version of the tool, and rotate

00:07:02  like this. If I wanted to twist the  finger, I can drag in the middle, and then

00:07:07  rotate through the Action Line.

00:07:08  Let's try another finger. Hold Ctrl,  drag with the Transpose tool activated,

00:07:20  and then let go. Invert the mask,  sharpen the mask, rotate to the side here and

00:07:28  I'm going to drag out the tool. So I'm  going to have this as my pivot, let's

00:07:33  reposition that a little  bit better, and then bend.

00:07:39  You can see this finger bent from  the side, it's in a slightly strange

00:07:47  position, so I can fix that. Drag out  from the knuckle here, maybe even drag in

00:07:57  the center to twist it.

00:07:58  If I want to fix this bend here, I can  switch over to Move mode, then drag on

00:08:05  the center, and reposition it that way.

00:08:11  Now when you use the Transpose tool,  it's a great way to pose your figures, but

00:08:14  remember that ZBrush just considers  this like a lump of clay, it doesn't know

00:08:18  that this is a finger anymore than  that this is a thumb, or that this is

00:08:23  anything else.

00:08:25  So what that means is, after you have  posed the model, using the Transpose tool

00:08:29  you are going to have to do some touch -up using the sculpting brushes. So I

00:08:32  will clear the mask, switch back to Draw,  and then zoom in using the Scale key,

00:08:43  remember to have your Local button,  that way. Centers the area that you are

00:08:51  working on. I can switch over to the  Smooth Brush, maybe reduce the size and

00:08:58  then just start smoothing this out,  and then I will just use my sculpting

00:09:01  brushes to fix any strange parts of  this model. Let's move that out a little bit.

00:09:06  So Transpose is a great way to get an  initial pose into your model. Transpose

00:09:14  also works with Symmetry. So let's take  a look at a symmetrical model, and I'm

00:09:20  going to click on the DefaultZScript  button here, bring up the startup screen

00:09:25  and let's take a look at Super AverageMan.

00:09:28  If I have him in Edit mode here and I  switch over to Move, I can drag out the

00:09:33  Transpose tool. I'm going to mask off  the body, and now I'm actually moving his

00:09:41  arm and stretching it like that.

00:09:43  But if I want to do both sides at the  same time, I can do this by activating

00:09:47  Symmetry. So let me expand the  Masking palette, clear the mask by pressing

00:09:52  Clear, go to Transform  Activate  Symmetry. When I do this, I actually get two

00:09:59  copies of the Transpose tool on either  side of the model. I can mask off the

00:10:05  center of the model. I'm going to just  quickly draw a marquee on here to mask

00:10:11  it out, and I'm going to blur the mask.  I'm going to move this right here to

00:10:17  about his shoulder, put this on his hand,  and switch to Rotate mode. Now when I

00:10:25  rotate one arm, the other arm rotates  as well. Usually it takes a little bit of

00:10:31  tweaking here to get it right, so  I'll use Move to bring this down a bit.

00:10:41  Switch to Rotate, move his arms forward,  and drag this out. I'm still in the

00:10:52  Rotate mode, drag in the center  and rotate these arms like this.

00:10:56  Now I'm moving very slowly, but when  you get accustomed to using the Transpose

00:11:03  tool, you are going to find that you  actually can start moving fairly quickly

00:11:07  once you get the hang of it.

00:11:08  There is one thing that I want to show  you that you should be very careful of

00:11:11  when you are working  with Transpose and Symmetry.

00:11:14  So let's clear the mask and I'm going  to move in closely to the head. Now if I

00:11:21  move to a Front View, I'm dragging  his head to pull out transpose, you'll

00:11:28  notice I have Symmetry on, so I have  symmetry on the axis. So any changes made

00:11:35  to this side is going to  be mirrored to this side.

00:11:36  If I switch to a side view, let's say I  want to make his head bend forwards. If

00:11:41  I drag up here, you are going to  notice that the tool snaps to the points of

00:11:47  the model. Mask his head, invert the  Mask Blur, and move it forward. It looks

00:11:58  pretty good!

00:11:58  The problem is, is that sometimes if  you are not careful from the side view,

00:12:05  and let's say I draw out a new tool  here, click on his nose and rotate. It

00:12:15  looks okay from there, but when I  switch to the Front View, his head has been

00:12:18  collapsed in on itself. So I  have this nasty problem right here.

00:12:22  The reason is, is that it's hard to  tell from the Side View but this is

00:12:26  actually at an angle. It is easy to  see from the Front View, this isn't an angle.

00:12:31  So when I rotate it from the Side View,  I actually collapse the head in on

00:12:34  itself. So to fix this, there are a  couple of precautions you can take when

00:12:39  drawing out the tool. I'm going to drag,  you could see that it's snapping to

00:12:42  the points of the model, it is very  useful sometimes, and sometimes it can lead

00:12:46  to problems like when you snap on the  nose and create an angle to the Transpose

00:12:51  tool. To avoid that I'm going to drag  all the way off to a blank part of the

00:12:55  canvas. When I rotate around, you are  going to see now it's straight up and

00:12:59  down. So when I rotate from a Side View,  and then switch to our Front View his

00:13:07  head has not collapsed in on  itself and everything looks good.

00:13:10  So once again, just to repeat that, if  you are going to rotate from a Side View

00:13:14  with Symmetry on, make sure you drag  to a blank part of the canvas so that it

00:13:19  is no longer snapping to the model.  When you do this, you know that the tool is

00:13:23  straight up and down.

00:13:27  And finally, if I drag and I hold  the Shift key, Transpose tool snaps to

00:13:33  angles, which sometimes can  help make the tool more precise.

00:13:37  So spend some time playing with the  Transpose tool, work with the hand models,

00:13:42  play with the models that came with  ZBrush. You will find that after a little

00:13:46  bit of practice, you get very fast with  it, and it becomes a very intuitive way

00:13:50  to pose the model.
