هنگامی که شما بر روی یک مدل دیجیتال در ZBrush کار میکنید، ممکن است بخواهید آن را انجام دهید
تغییرات در مدل. تغییرات را می توان برای انیمیشن و یا یک عدد استفاده کرد
از اهداف دیگر برای انجام این کار، می توانید از اهداف مورف استفاده کنید. اهداف مورف یک است
ابزار بسیار متنوع. برای نشان دادن اینکه چگونه کار می کنند، من قصد دارم بارگذاری کنم
مدل oldMan_Painted. من قصد دارم آن را به بوم بکشم و سپس به یاد داشته باشید،
شما می خواهید به حالت ویرایش بروید برای انجام این کار می توانید دکمه T را نیز فشار دهید. من کلید F را فشار می دهم تا مرکز
مدل و سپس هنگامی که شما می خواهید برای ذخیره یک مورف هدف، شما به سادگی به ابزار بروید
پالت و گسترش مورف هدف و همه شما باید انجام دهید این است مطبوعات فروشگاه MT،
این ذخیره سازی برای مورف هدف است. هنگامی که این دکمه ها را در دسترس می بینید، پس شما
00:00:44 می دانید که هدف Morph ذخیره شده است.
00:00:46 شما همیشه می توانید یکی از مورف Target را برای هر مدل خاص ذخیره کنید، اما
00:00:50 حالا که من Morph Target را ذخیره کرده ام، من قصد دارم به Brush Move بروید
00:00:55 و زوم کنید و اگر میخواهید عاشق پیر باشید، همه چیزهایی که باید انجام دهید این است که
00:00:59 شروع به کشیدن بر روی ابرو خود، شاید این را بالا ببرید. من متضاد هستم
00:01:06 به طوری که می دانید که هر دو ابرو به همان شکل در خارج مطرح می شوند
00:01:14 و در همان سطح برداشته شده در داخل، بیایید این را به دست آوریم.
00:01:17 من آن را کمی بالا می برم، او را واقعا نگاه عصبانی. حالا من ساخته ام
00:01:24 این تغییرات، اما اگر می خواهم دوباره به نسخه اصلی بازگردم، می توانم بگویم
00:01:27 دکمه سوئیچ را فشار دهید و این بین دو نسخه مدل تغییر می کند.
00:01:32 من همچنین می توانم از کشویی استفاده کنم. اگر به سمت چپ بکشم، شروع به غلبه بر این می کنم
00:01:41 مورف و اگر آن را به سمت راست بکشیم، این مقدار مورف و
00:01:48 اگر می خواهم تغییراتی را که من در مدل ایجاد کرده ام را متوقف کنم، می توانم حذف کنم
00:01:52 Morph Target و Morph Target را از حافظه حذف و ذخیره می کند
00:01:57 به عنوان بخشی دائمی از مدل تغییر می کند.
00:01:59 I'm going to undo that, so that I have my Morph Target still available. Another
00:02:04 way that Morph Targets can be useful, if you remember, as you start a session
00:02:08 working on a model, you probably want to store a Morph Target from the very
00:02:12 beginning. Now one of the reasons you might want to do this is, so that you can
00:02:15 use the Morph brush. The Morph brush actually allows you to paint the changes
00:02:21 between the model and the stored Morph Target. So I have a Morph Target stored,
00:02:27 I can tell because I have these buttons available and I can lower the brush
00:02:31 size here and as I start painting on the model, what's going is it's actually
00:02:36 painting back to the original shape of my model.
00:02:41 I'm going to undo those changes. The Morph Target can be thought of as an undo
00:02:47 brush. As I make changes to my model, I can lower the intensity and then very
00:02:53 selectively paint and undo on the model. Let's say I wanted to make a change
00:02:57 just to that part, now I have that available. So this is a one reason why you
00:03:02 probably want to store a Morph Target right when you start working on a model.
00:03:05 Because if you have made a change, let's say I have made something with the
00:03:10 Standard brush, I'm going to switch to Standard and I'm going to make just a
00:03:15 radical change here and I have decided that I like the parts of the stroke and
00:03:20 I don't like others. I can switch to the Morph brush and paint out the parts
00:03:26 that I don't like. You kind of wish that every program had this kind of ability
00:03:32 to sort of paint, undo on to the surface of the changes.
00:03:35 I think it would be hard to implement it in something like excel, but I'm sure
00:03:39 somebody can figure how to do it. Then we go, I have erased all those changes.
00:03:42 ZBrush is a great way to create blend shape targets. If I decide that I want to
00:03:50 animate this character into program such as Maya, I can first create my initial
00:03:55 sculpt with a neutral pose, like this and then store a Morph Target and go
00:04:01 through and make changes to just isolate the parts of the face.
00:04:04 Most animators will prefer that their blend shape targets, their various facial
00:04:08 expression models have only one change to part of the face at a time. In that
00:04:12 way, they can switch between the different parts of the face and blend those
00:04:16 together to make expressions. So if I bring my neutral pose in here and store a
00:04:21 Morph Target and then start to make changes to just, say the eyebrows, I can
00:04:28 save this version of the model out, and say, eyebrows up and hand that over to
00:04:33 my animator and make about 20 or 30 other blend shape targets, very quickly.
00:04:38 I have actually made probably 30 blend shapes in a matter of hour using ZBrush.
00:04:43 The same amount of work in Maya would take a lot longer. But a lot of animators
00:04:48 prefer to have isolated at one side of the face, so they like to have the
00:04:54 symmetrical eyebrow raise, but they only need one at a time. So to do this, I
00:04:58 can actually mask off half of the face, then use the Morph brush, turn the
00:05:06 Intensity all the way up, and carefully, paint out the changes made on this
00:05:15 side of the face when I remove the mask. So I'm going to the Masking palette
00:05:19 and pressing Clear. Now I have the character that has an eyebrow raised of one
00:05:25 side of the face and now you can go back, I can save this out as left eyebrow
00:05:31 raised, hit Ctrl+Undo a few times and then just do the other side, so I can
00:05:36 mask this out.
00:05:38 Choose the Morph brush, paint on this side and now I can save this version out
00:05:43 with his right eyebrow raised. Of course, I'm talking about his right eyebrow
00:05:47 and from his perspective. So that's a great way that Morph Targets and the
00:05:51 Morph brush can be used together to quickly make blend shape targets for your
00:05:54 model and like I say, you will find that it makes the workflow for something
00:05:58 like facial expression models, much more pleasant and much, much faster.
