ZBrush拋光軍靴

本教程文章的想法是演示如何將粗略的模型拋在一個拋光的最后的外觀，干凈的細節(jié)都不會離開ZBrush。 它涵蓋了諸如網(wǎng)格提取，網(wǎng)格清理，ZRemesher和面板循環(huán)等步驟，并在曲線和自定義創(chuàng)建的插入網(wǎng)格畫筆的幫助下添加了針跡細節(jié)。 本教程的重點是網(wǎng)格的一部分，但這些步驟可以應(yīng)用于整個模型。

The idea of this tutorial article is to demonstrate how to take a rough model to a polished final look, with clean details all without leaving ZBrush. It cover steps such as mesh extraction, mesh cleanup, with ZRemesher and panel loops, and adding stitches detail with the help of curves and custom created insert mesh brush. The tutorial focus on one part of the mesh but these steps can be applied all over the model.

Step 1: Mesh Extraction

On the rough ZBrush mesh, paint a mask on areas that we want to extract and be its own mesh. In Tool > SubTool, click on 'Extract' and then, if you are happy with the preview, press 'Accept' to finally get the new mesh as another SubTool. The Extract settings may vary but I usually set the 'S Smt' to 100 if the rough mesh is high resolution.

步驟1：網(wǎng)格提取

在粗糙的ZBrush網(wǎng)格上，在我們要提取的區(qū)域上繪制一個蒙版，并將其作為自己的網(wǎng)格。 在“工具”>“子工具”中，單擊“提取”，然后，如果您對預(yù)覽感到滿意，請按“接受”，最終獲得新的網(wǎng)格作為另一個“選項”。 提取設(shè)置可能有所不同，但如果粗網(wǎng)格高分辨率，我通常將“S Smt”設(shè)置為100。

Step 2: Mesh Cleanup Process

The new extracted mesh needs some cleanup to look good and work with. This process basically involves ZRemesher and Panel Loops. In this case, I find that ZRemesher will work best if the mesh is hollow, so first thing to do is isolate the outer (reddish) polygroup and 'Delete Hidden' to keep only what is visible, and then hit 'ZRemesher'. After that, use 'Panel Loops' to get the thickness back. We just want a simple shell result, so watch those settings. 'RegroupPanels' and 'RegroupLoops' are useful to unify the polygroups. A final touch is to extrude the shell border with the ZModeler brush to get an extra loop with consistent width.

步驟2：網(wǎng)格清理過程

新提取的網(wǎng)格需要一些清理才能看起來很好，并且可以使用。 這個過程基本上涉及到ZRemesher和面板循環(huán)。 在這種情況下，我發(fā)現(xiàn)如果網(wǎng)格是空洞的，ZRemesher將會工作得最好，所以首先需要做的是隔離外部（紅色）多組和“刪除隱藏”，只保留可見的內(nèi)容，然后點擊“ZRemesher”。 之后，使用“面板循環(huán)”來獲得厚度。 我們只需要一個簡單的shell結(jié)果，所以看這些設(shè)置。 “RegroupPanels”和“RegroupLoops”可用于統(tǒng)一多組。 最后一點是用ZModeler畫筆擠壓外殼邊框，以獲得一個寬度一致的額外的循環(huán)。

Step 3: Making the Stitch Brush

Before heading to the next step, we need to create a brush that will insert the stitches on the model. With ZSpheres we can quickly create the stitch object. It is important to keep this insert object somewhat low-res because it will be duplicated hundreds of time on the target mesh. It is also a good idea to create variations of the stitch so we have multiple options within the same brush.

步驟3：制作針跡刷

在進入下一步之前，我們需要創(chuàng)建一個將模型上插入針跡的畫筆。 使用ZSpheres，我們可以快速創(chuàng)建針跡對象。 保持此插入對象有點低分辨率是重要的，因為它將在目標網(wǎng)格上復(fù)制數(shù)百次。 創(chuàng)建針跡的變體也是一個好主意，所以我們在同一個畫筆中有多個選項。

Step 4: Adding the Stitches

With the target mesh cleaned up and the Insert Mesh brush ready; it is time to add the stitches. Since the mesh has multiple polygroups, it is necessary to isolate the target areas (in this case the yellow polygroup) to frame the mesh with curves based on its border. In Stroke menu > Curve Functions, press 'Frame Mesh' to draw the curves. Then, unhide the polygons and, with the stitch brush selected, click on the curve to apply the stitches. If you prefer, press 'M' to select the double-stitch option and click on the curve again to replace the stitches. Once you are happy with the result, click anywhere inside the mesh to commit the stitches.

步驟4：添加針跡

清理目標網(wǎng)格，插入網(wǎng)格畫筆就緒; 現(xiàn)在是添加針跡的時候了。 由于網(wǎng)格具有多個聚類，因此必須將目標區(qū)域（在這種情況下為黃色聚合物）分離，以便根據(jù)其邊框的曲線來對網(wǎng)格進行構(gòu)圖。 在“行程”菜單>“曲線函數(shù)”中，按“框架網(wǎng)格”繪制曲線。 然后，取消隱藏多邊形，并選擇針跡刷，單擊曲線以應(yīng)用針跡。 如果您愿意，請按“M”選擇雙針選項，再次單擊曲線以替換針跡。 一旦你對結(jié)果感到滿意，點擊網(wǎng)格內(nèi)的任何地方提交針跡。

Step 5: Final Model

And here is the final model. I used these techniques multiple times in different ways. I also used different types of stitches as well as different sizes. The details are sharp, clean and polished.

步驟5：最終模型

這是最后的模型。 我以不同的方式多次使用這些技術(shù)。 我也使用不同類型的針跡以及不同的尺寸。 細節(jié)清晰，清潔和拋光。
