اگر میخواهید سکته مغزی و اشیاء را که در 2.5D نقاشی شده اند، تغییر دهید

00:00:05 بوم، شما قصد استفاده از Transform Gyro را خواهید داشت. برای نشان دادن این، من

00:00:09 سند robot_island باز است بنابراین من فقط برای باز کردن robot_island.zbr، و

00:00:16 این برای کاربران حق بیمه در دسترس است.

00:00:18 من Sphere Brush خود را از براش های 2.5D انتخاب کرده ام در اینجا. من کردم

00:00:24 مواد شیدر سریع و یک رنگ قرمز زیبا. من فقط شروع به نقاشی میکنم

00:00:30 اینجا در اقیانوس و بخشی از جزیره. من در واقع نقاشی در سه است

00:00:37 ابعاد برای ایجاد این 2.5D سکته مغزی.

00:00:40 برای حرکت دادن این، می توانم روی Move حرکت کنم و Gyro ظاهر شود و البته

00:00:46 سکته مغزی ناپدید می شود بنابراین چه اتفاقی افتاده است با تغییر حالت به حالت حرکت سکته مغزی

00:00:50 در حقیقت کمی پشت سر گذاشته شده است. بنابراین اگر من فقط شروع به کشیدن

 با Gyro Transform، من می توانم سکته مغزی را ببینم. من می توانم آن را تغییر دهم

 در صحنه. اگر میخواهم چرخش کنم، به حالت چرخش تغییر میکنم و میتوانم چرخش را شروع کنم

سکته مغزی دور مقیاس؛ من می توانم آن را کاهش دهم.

00:01:14  So let's take a close look at the  controls of the Gyro itself, because this is

00:01:18  the kind of thing that can trip you  up when you are first starting to use ZBrush.

00:01:20  I will switch to Move mode here, and if  I want to move this upwards, I click on

00:01:26  this crossbar right here, right at  this intersection here. I can drag on the

00:01:32  yellow part to move it backwards and  forwards, and the green part right here.

00:01:37  I can also drag up or down on the blank  part of the canvas, away from the tool

00:01:43  to move this backwards or forwards. So  I'm just repeatedly dragging up to move

00:01:47  backwards, repeatedly  dragging down to move forwards.

00:01:50  The thing that trips up a lot of new  users is, what happens when I start

00:01:54  dragging here in the center of the tool?  Well, I get this very strange behavior.

00:01:59  What's happening is, this is actually  very useful behavior, but it looks a

00:02:03  little odd at first. It's actually  repositioning the stroke based on the

00:02:07  normals of what's beneath the stroke.  In other words, as I drag it over the

00:02:11  ocean here, it repositions it based on  where the ocean water is facing. I drag

00:02:18  it on the shark fin, you can sort of see,  it's trying to reposition it based on

00:02:22  the shark fin, and then again over the island.

00:02:26  What's useful about this is, if I have  the stroke and it's positioned far away,

00:02:30  and I want to quickly move it to the  island, I can just drag it on top of the

00:02:33  island, and there it is. That is a  great way to bring this stroke forward very,

00:02:37  very quickly, rather than having to  drag like this repeatedly. But it does work

00:02:41  in a really strange way, and  it takes some getting used to.

00:02:43  If I switch to Rotate mode; this is a  little bit more intuitive, and I drag on

00:02:47  this crossbar, I can rotate parallel to  the canvas. So this gray circle here is

00:02:54  the part that's parallel to the canvas.  But I can also restrict the rotation by

00:02:59  dragging on any of these other  crossbars. Then if I want to free form rotate,

00:03:05  just drag here in the center.

00:03:07  Scaling works in a very similar way.  I can scale it non-proportionally by

00:03:09  dragging on the crossbars, or  proportionally by dragging in the center. So that

00:03:18  works fairly simply.

00:03:19  It's really just Move mode that takes a  little bit of practice getting used to.

00:03:23  The other thing that you should  understand about the Transform Gyro is, as I'm

00:03:26  repositioning in this, if I do Ctrl+Z  to undo, nothing is going to happen. The

00:03:32  problem is, is that, ZBrush considers  all of the changes that you make while

00:03:37  this tool is active as one action. So  as I reposition it and switch back to

00:03:42  Draw mode, then I can Undo; and  generally it will just undo the stroke on the

00:03:47  canvas altogether.

00:03:48  That's something else that takes a  little bit of getting used to. It would be

00:03:51  nice if you could actually undo the  changes you make to the stroke while the

00:03:54  tool is active, so it  takes a little bit of practice.

00:03:57  So I just drew another stroke onto the  canvas using the Sphere Brush; I drew it

00:04:01  on the island. When I switch to Move,  it flipped all the way behind the island.

00:04:06  So if I just drag here, I can get it  back quickly. It's stuck to the island

00:04:12  now, and now I can carefully reposition  it by dragging on the crossbars of the tool.

00:04:17  So practice the tool, and once you get  the hang of it, it will start to make a

00:04:22  little bit more sense, and you will  find it's a great way to position objects

00:04:26  in the scene.

00:04:27  For instance, as I worked on these  clouds here, I just sat there moving them

00:04:31  back and forward until I was happy  with where they are. The same with each of

00:04:35  the parts of the robot.

00:04:36  If I dropped the tool to the canvas  by switching to Draw mode, and choosing

00:04:41  another brush, or painting another  stroke onto the canvas, I'm no longer able

00:04:46  to move this, this is now frozen in  space, so it's dropped to the canvas.

00:04:51  If I wanted to get rid of it, I could  switch to the Eraser Brush, and then just

00:04:55  remove it using the Eraser. Of course,  I have to be careful, because I could

00:04:58  start erasing parts of the ocean  here. The robot has been rescued now.

00:05:02  Practice with the Transform Gyro  until you get the hang of it, and just

00:05:07  remember that the Move mode is the one  that's probably going to cause you the

00:05:09  most trouble when you are first starting,  but if you are patient with yourself

00:05:12  you will find that it does make sense.
