دانلود آموزش زیبراش Illustrating with ZBrush Using snapshots

اگر شما یک تصویر 2.5D در Zbrush ایجاد می کنید، و شما می خواهید به سرعت

 از یک شیء برای ایجاد یک صحنه با آن کپی کنید، می توانید از Snapshot استفاده کنید

 تابع به سرعت این کار را انجام دهید، و من قصد دارم این را در context نشان دهم

 ایجاد یک تصویر 2.5D واقعی. من بوم من اینجا هستم بیایید زوم کنیم

 بنابراین کشیدن روی دکمه زوم، فقط می توانیم کل بوم را ببینیم، و من دوست دارم

 برای گرفتن یک آبی رنگ آبی آسمان در اینجا. بنابراین من منوی سند را گسترش می دهم

 با کلیک روی Back و انتخاب رنگ آبی، شیب آبی زیبا و آبی، و من

00:00:38 فکر می کنم که به نظر می رسد بسیار خوب است. بنابراین من می خواهم یک زمین بیابانی ایجاد کنم.

00:00:42 بنابراین برای انجام این کار، کتابخانه ابزار را گسترش خواهم داد و قصد دارم این را انتخاب کنم

00:00:46 Object Terrain3D، من آن را انتخاب کرده ام، بنابراین من می توانم بر روی بوم آن را قرعه کشی.

00:00:53 با کلیک بر روی T برای تغییر حالت ویرایش، یا این دکمه را در اینجا فشار دهید. بیایید چرخش کنیم

00:00:56 بنابراین شما می توانید ایده خوبی که این به نظر می رسد. من قصد دارم ابتدایی را گسترش دهم

00:01:02 پالت، و مشخصات افقی و منحنی را گسترش دهید. در حال حاضر می تواند در واقع

00:01:09 شروع به تغییر شکل Terrain فقط با حرکت دادن این نقاط در

 منحنی ویرایش  So that's the horizontal access. If I  expand the vertical access, it works the

00:01:22  same way. Let's make a few lumps in  here. Pretty good to start, I want to add

00:01:30  few more lumps using the Sculpting  Brushes. So if I paint on this right now, I

00:01:34  get a warning. So what do I need to do?  Well, ZBrush is giving me a good hint

00:01:38  here; I need to make this a Poly  Mesh so I can sculpt with the sculpting

00:01:42  brushes. So I go to this button right  here, press Make Poly Mesh 3D, there we go.

00:01:49  Now I have my Standard brush selected  as a Sculpting brush, and I can go in

00:01:53  here, maybe make some few more hills,  this whole structure look more like an

00:01:58  uneven ground. I can smooth these out  by holding the Shift key, that activates

00:02:03  the Smooth brush; here we go, that  looks good. Let's divide it a few times, one

00:02:13  more time, so this is nice and smooth,  and I'm going to switch out of Edit

00:02:17  mode, and pressing the Move button to  activate the gyro. Now I can move this

00:02:23  around on the canvas.

00:02:24  Let's switch to Rotate and Scale, back  to move, until it all becomes a second

00:02:38  nature. Just want to position this, so  it looks like ground, and I'm getting a

00:02:43  little bit of strange behavior.  Sometimes it's easier to drag on the center of

00:02:48  the gyro, rather than on these  crossbars. Occasionally you get some kind of

00:02:53  flipping, that will be a bit  distracting. I want to change the material to

00:02:59  BasicMaterial, and nice brown color,  tan to make it look like sand, and one

00:03:11  more adjustment, is to  scale it down a little bit.

00:03:15  So I went and dropped the desert floor  to the canvas, in other words it's now

00:03:18  converted to the pixels. To do that,  I switch back to Draw, and I no longer

00:03:24  have Edit activated. So now I'm free  to take another brush and start painting

00:03:30  on the canvas, and this has been  converted to pixels. So it is no longer a 3D

00:03:35  object, it's essentially a large 2. 5D Paint Brush stroke, and I want to

00:03:41  populate this desert floor with some  robots. I already have a robot model

00:03:46  created. So I'm going to load it. I go  into the Tool menu, press Load tool, and

00:03:52  I'm going to choose the robot_subtools  model right here. When I select this, it

00:03:58  loads into the tool panel, and  now I can draw it on to the canvas.

00:04:03  I can start to position it on the  canvas by selecting Rotate, or Transform Gyro

00:04:09  appearance. Now I can rotate him  around. Of course, he is the color and

00:04:14  material as the ground. So let's change  that by choosing -- let's try intensity

00:04:19  metal, and give him more of a silver  color. So now he is looking good in terms

00:04:26  of his material and color, nice and  robotic. He is a little bit large, so I'm

00:04:30  going to switch to Scale to scale him  down, and move very carefully with the

00:04:37  move function of the Gyro, I'm  going to position him, and rotate him.

00:04:47  Now what I want to do, is make a copy  of him very quickly. So that can crate a

00:04:51  snapshot, and the snapshot just makes  the copy of the robot exactly in the same

00:04:56  position. I can move that copy, and  then the original robot will be dropped to

00:05:00  the canvas. In other words, it will be  converted to pixels, and I can no longer

00:05:03  manipulate it as a 3D tool,  that's exactly what I want.

00:05:07  To make a copy I can expand the  Transform palette, and click on this little

00:05:12  camera, that makes the copy. Switch to  Move, and now I can pull the copy to the

00:05:19  side, and I can rotate him, and maybe  move him forward, scale him up, bring him

00:05:28  down, perhaps too far forward, so I  can just drag back on the canvas here, a

00:05:37  little bit of a rotation, some more  movement, and you get the basic idea.

00:05:44  If you are big fan of using hot keys to  make a snapshot, you press Shift+S, and

00:05:54  then I can just intentionally position  this guy, I'm just dragging him back and

00:06:00  forth on the canvas, to move him back  in space. You will notice that when I

00:06:03  move him backwards and forwards in space,  he is not actually changing size. He

00:06:08  is just changing his position in  terms of depth, kind of a strange thing to

00:06:12  wrap your head around, because we are  used to things appearing smaller as they

00:06:16  recede into the distance.

00:06:17  But in the case of an illustration it  actually, it works just fine. I can scale

00:06:25  him separately from his position. And  there we go. On my way to creating my

00:06:30  army of robots. Shift+S to make the  snapshot, appearing backwards on the canvas

00:06:38  to move him back. And scale him down.  Switch back to Move, carefully position.

00:06:45  Remember if I drag right here, he is  going to start flipping around which is

00:06:49  fun to watch, but it can be little  bit disconcerting. When I'm doing this

00:06:53  what's happening, is he is rotating  based on the normal of whatever is behind

00:06:58  the object. So if I drag on the  background of the canvas right here, he is just

00:07:03  perpendicular, but it is very useful  if I decided I quickly want to bring him

00:07:07  in front of this robot, I can drag him  on top of the robot, and then rotate him

00:07:13  around, switch to Move, drag him  down a little bit, and may we scale him upwards.

00:07:21  It takes little bit of practice, but  after a while you will become an expert,

00:07:26  positioning objects on the canvas. And  there is our robot army, very quickly

00:07:30  created using these Snapshot function.
