了解基本知識(shí)：使用ZBrush進(jìn)行呈現(xiàn)

繼續(xù)上一個(gè)關(guān)于材料和照明的教程，我們將看看渲染菜單及其一些參數(shù)來(lái)完成此角色，然后再進(jìn)入Photoshop中的最終合成。

Continuing from the previous tutorial about materials and lighting, we will have a look at the render menu and some of its parameters to finish this character before moving into the final compositing in Photoshop.

Step 1: Render mode and properties

To start, let's have a look at the different render mode and an overview of the Render Properties menu. The four buttons (Best, Preview, Fast and Flat) are the render modes for how your model will be rendered in real-time in the canvas. Each of these modes render more or less effects. The Preview mode is the default one. Click and drag the cursor button on a part of your model to render this section in Best render mode. In the Render Properties menu, you will find the buttons to turn the different effects off and on that would be visible during render time (BPR) or in real-time, such as the Wax Preview.

步驟1：渲染模式和屬性

首先，我們來(lái)看看不同的渲染模式和“渲染屬性”菜單的概述。 四個(gè)按鈕（最佳，預(yù)覽，快速和平滑）是渲染模式，用于在畫布中實(shí)時(shí)渲染您的模型。 這些模式中的每一個(gè)都產(chǎn)生或多或少的效果。 預(yù)覽模式是默認(rèn)模式。 單擊并拖動(dòng)模型的一部分上的光標(biāo)按鈕，以最佳呈現(xiàn)模式呈現(xiàn)此部分。 在“渲染屬性”菜單中，您會(huì)發(fā)現(xiàn)按鈕可以在渲染時(shí)間（BPR）或?qū)崟r(shí)（例如“蠟預(yù)覽”）中顯示不同的效果。

Step 2: RenderPass menu and BPR render

The BPR button will render the model on the canvas (Shift+R) with all effects (Shadows, Fibers, AO, Transparency, and so on). After rendering your scene, the different passes rendered will be available for you to export. To export these passes, just click on each of the passes you want to export.

步驟2：RenderPass菜單和BPR渲染

BPR按鈕將使畫布上的模型（Shift + R）具有所有效果（陰影，光纖，AO，透明度等）。 渲染場(chǎng)景后，渲染的不同通行將可供您導(dǎo)出。 要導(dǎo)出這些通行證，只需單擊要導(dǎo)出的每個(gè)通行證。

Step 3: Render object transparency

To render the transparency of an object in ZBrush, you will have to enable a few things. Enable the Transparent button in the Render Properties menu. In the BPR Transparency, you will find a few more advanced settings. Then select the SubTool you want and in the Display Properties, click on BPR Settings and finally enable the BPR Transparent Shading button. Move the BPR Visibility slider to modify its transparency.

步驟3：渲染對(duì)象的透明度

為了在ZBrush中渲染一個(gè)對(duì)象的透明度，你必須啟用幾件事情。 在“渲染屬性”菜單中啟用“透明”按鈕。 在BPR透明度中，您會(huì)發(fā)現(xiàn)一些更高級(jí)的設(shè)置。 然后選擇所需的SubTool，然后在顯示屬性中，單擊BPR設(shè)置，最后啟用BPR透明陰影按鈕。 移動(dòng)BPR可見性滑塊以修改其透明度。

Step 4: BPR Shadow and BPR AO

You can enable the Shadows and Ambient Occlusion (AO) in the Render Properties, and find their advanced settings in their respective BPR Shadow and BPR AO menu. Those settings will modify the shadows and AO for the BPR render only.

步驟4：BPR陰影和BPR AO

您可以在渲染屬性中啟用陰影和環(huán)境遮擋（AO），并在各自的BPR陰影和BPR AO菜單中查找其高級(jí)設(shè)置。 那些設(shè)置將僅修改BPR渲染的陰影和AO。

Step 5: Preview Shadow and Preview Wax

If you want to have a wax effect on your model in the canvas in real-time, even while sculpting, you will have to enable the WaxPreview button in the Render Properties menu. Then in the Material palette, under the Wax preview menu, you will find the parameters to modify this effect on the material. Additionally, you will find the settings for the Wax preview for the preview render in the Preview Wax menu in the Render palette.

步驟5：預(yù)覽陰影和預(yù)覽蠟

如果您想在畫布中實(shí)時(shí)地對(duì)模型產(chǎn)生蠟效果，即使在雕刻時(shí)，您也必須在“渲染屬性”菜單中啟用“WaxPreview”按鈕。 然后在“材質(zhì)”調(diào)色板中的“Wax預(yù)覽”菜單下，您可以找到修改材料效果的參數(shù)。 此外，您將在“渲染”選項(xiàng)板中的“預(yù)覽蠟像”菜單中找到預(yù)覽渲染的蠟預(yù)覽設(shè)置。

Step 6: BPR filters overview

You can add filters to your BPR render directly in ZBrush. Do a BPR render, then enable the filter by clicking on the small circle on the top-right corner of the F- button. When this small circle is open, the filter is on and when it's full the filter is off. You can add more filters by clicking on another F button and choosing the type of filter you want to apply to your render. After choosing your filter, you will find all its parameters under the selection filter button.

步驟6：BPR過(guò)濾器概述

您可以直接在ZBrush中為BPR渲染添加過(guò)濾器。 執(zhí)行BPR渲染，然后通過(guò)單擊F按鈕右上角的小圓圈啟用過(guò)濾器。 當(dāng)這個(gè)小圓圈打開時(shí)，過(guò)濾器打開，當(dāng)過(guò)濾器已滿時(shí)，過(guò)濾器關(guān)閉。 您可以通過(guò)單擊另一個(gè)F按鈕并選擇要應(yīng)用于渲染的過(guò)濾器類型來(lái)添加更多過(guò)濾器。 選擇過(guò)濾器后，您可以在選擇過(guò)濾器按鈕下找到所有參數(shù)。

Step 7: Depth Cue Overview

The Depth Cue will render a depth effect following the parameters in the Depth Cue menu in the Render palette. The Depth1 slider will be the distance where the sharp focus will be, and the Depth2 slider will be the distance where the objects will have the softest focus on the canvas. You can, either choose your distance with the slider or click and drag from the slider to the canvas where you want the focus of this slider to be. This effect will be visible only with the Best renderer and the BPR render.

步驟7：深度提示概述

“深度提示”將根據(jù)“渲染”調(diào)色板中“深度提示”菜單中的參數(shù)進(jìn)行深度效果。 Depth1滑塊將是銳焦點(diǎn)的距離，Depth2滑塊將是對(duì)象在畫布上具有最輕焦點(diǎn)的距離。 您可以選擇與滑塊的距離，或單擊并從滑塊拖動(dòng)到需要此滑塊的焦點(diǎn)的畫布。 只有最佳渲染器和BPR渲染才能看到此效果。

Top tips: Help in ZBrush

If you ever wonder what a particular button, slider, and so on, do in ZBrush, just put your mouse over it and hold CTRL. A window will then appear explaining you what it does.

熱門提示：ZBrush幫助

如果您想知道ZBrush中的特定按鈕，滑塊等等，只需將鼠標(biāo)懸停在其上并按住CTRL即可。 然后會(huì)出現(xiàn)一個(gè)窗口，說(shuō)明它是什么。
