بنابراین هنگامی که شما با Alphas در ZBrush کار می کنید، به شما محدود نمی شود آنچه در این کتابخانه در اینجا وجود دارد، پتانسیل خلاقانه ای در آن وجود دارد ایجاد Alphas خود را. من قصد دارم به شما نشان دهم چگونه آلفا خود را ایجاد کنید درست در اینجا در ZBrush. در حال حاضر، من oldMan من که من کار کرده است. من قصد دارم سوئیچ کنم حالت تصویر و رنگ به طور مستقیم بر روی بوم. برای انجام این کار، من از آن خارج می شوم حالت ویرایش؛ این به بوم رها شده است، بنابراین دیگر به عنوان یک موجود نیست مدل سه بعدی اما این درست است زیرا همه این تغییرات در اینجا در اینجا ذخیره می شوند پالت ابزار، و تا زمانی که من جلسه ZBrush رفتن، که برای من در دسترس خواهد بود. همیشه یک ابزار خوب برای ذخیره ابزار شما است، بنابراین من قصد دارم این کار را انجام دهم اکنون. من قصد دارم با این مرد، oldMan_ alphas تماس بگیرم، و من قصد دارم او را نجات دهم. این است رفتن به من بپرسید که آیا میخواهم آلفای انتخاب شده در حال حاضر را ذخیره کنم. من قصد دارم نه را انتخاب کنید، زیرا این یکی از پیش فرض ZBrush Alphas است، اما اگر من خودم را داشته باشم آلفا در اینجا، من می توانم آن را با ابزار ذخیره کنم. بنابراین حالا میخواهم Ctrl + N را فشار داده و صفحه را پاک کنم، و من قصد دارم تغییر دهم اندازه سند من دکمه Constrain Proportions را خاموش کنید. بیایید این را وارد کنیم سینی را با کلیک راست بر روی آن وجود دارد. 512x512، تغییر اندازه، به نظر می رسد خوب است. حالا من هستم آماده شروع به ایجاد Alphas خودم هستم

00:01:24  To start with, I'm going to go to the  Tool palette and I'm going to choose my

00:01:28  Regular PaintBrush. I'm going to lower  the Draw Size. I want to create sort of

00:01:35  a crosshatching Alpha, something that I  can use to create fine wrinkles on the skin.

00:01:39  Now, I'm just going to start drawing on  the canvas. I'm varying the pressure on

00:01:43  the tablet. When I do that, I get  thinner lines with less pressure, thicker

00:01:48  lines with more pressure. So let's do  this. Open the breaks in there is good.

00:01:54  Maybe just a couple of dots here.  It's good to keep your Alphas nice and

00:02:04  simple, makes them a little bit more versatile.

00:02:07  Then once I'm finished painting on the  canvas, to convert this to an Alpha, I

00:02:12  go to the Alpha menu, and I choose  GrabDoc. Now this alpha is available to me

00:02:19  right here in the Alpha  palette, here in the User Alphas.

00:02:23  I'm going to create another one just  to show you some of the other aspects of

00:02:28  working with Alphas. To do this, I'm  going to choose Sphere3D and I'm going to

00:02:33  start dragging spheres on the canvas.  Some are going to be closer; some are

00:02:42  going to be farther away. Some are  small and some are large. All I'm doing is

00:02:52  just dragging these spheres on top of  each other. I'm going to go a little bit

00:02:57  faster now and start filling the screen.

00:03:00  Of course, if I really want to go fast  I can switch to Spray. Increase the Draw

00:03:17  Size. There we go. Now I have really  got some spheres coming. It's going to be

00:03:21  an interesting texture for sure.

00:03:29  Maybe make a few more big ones right  here in the front. Now I'm going to create

00:03:36  an Alpha from this image. To do that,  I'm going to go to the Alpha palette and do GrabDoc.

00:03:44  Let's take a look at this Alpha by  hovering over it. What you will notice is

00:03:48  that it has actually stored the depth  information as a value on the Alpha.

00:03:53  Those parts of the image that are  farther away from us are darker and those

00:03:57  that are closer to us are lighter.  This is going to create some very

00:04:01  interesting effects.

00:04:03  So I'm going to create a New document.  I don't need to save the changes, I

00:04:09  press No. I still have my Alphas, both  of them, and I still have my tool. So

00:04:16  I'm going to take the oldMan Alpha's  tool, I'm going to drag him on here.

00:04:21  Switch to Edit mode, and I'm going to  zoom in. I have got my Standard brush

00:04:27  loaded, so I'm going to switch to the  first Alpha that I made, and with the

00:04:33  DragRect selected, just start drawing  out here. That looks like some scarring.

00:04:39  So let's hold the Alt key so it's  digging in. I'm just going to create a

00:04:46  crosshatching pattern here on  the skin by dragging across.

00:04:49  It doesn't look very realistic at this  point, until I start smoothing it out.

00:04:57  So I'm holding the Shift key and just  smoothing out on top. Blending where I

00:05:02  need to. As you layer these wrinkles  on top of each other, and continue to

00:05:09  smooth and vary the size, you start to  get some very realistic looking wrinkles.

00:05:18  It's all about variation and creating  organic looking details. I'm varying the

00:05:23  Size; maybe you can vary the Intensity.  I have raised the Intensity, so dig in

00:05:29  a little bit more. I'm just  overlapping them. You can see, it starts to make

00:05:35  some very interesting wrinkles.

00:05:36  Let's see what happens when I choose  the other Alpha. You can see when I drag

00:05:44  on here, those white parts are  actually closer and the darker parts make less

00:05:50  of impression. I hold the Alt key, I  get the opposite. Now, of course, this is

00:05:54  going to end up looking a bit like  some kind of skin problem and less like an

00:05:57  organic detail, but I just wanted  to show you how the lightness and the

00:06:01  darkness of the Alpha actually affect it.

00:06:05  One other thing is you might want to  get rid of this square shape around the

00:06:09  Alpha. To do that, we can go to the  Alpha palette. I'm going to put this in the

00:06:15  tray. We have a bunch of controls  here that allow us to vary the Alpha.

00:06:20  The RF or the Radial Fade is a very  useful one for creating a nice circular

00:06:25  border to the Alpha. So now it sort of  fades out at the edges, and I don't have

00:06:29  that nasty square shape around it.

00:06:34  Just like sculpting in ZBrush, you can  get lost in creating your own Alphas,

00:06:37  and I think that you should spend  sometime doing that. See what you can come up

00:06:40  with and see how the Alphas affect  the detailing you do on your 3D models.
