巨型機(jī)器貓的制作

在本教程中，我將向您展示如何建模這個角色并分享進(jìn)度和一些渲染輸出和后期工作效果。 2D的概念，我最喜歡的藝術(shù)家之一的CreatureBox，我的畫廊基本上一半的靈感來自他們的人物。

In this tutorial I'll be showing you how I approached modeling this character and sharing the progress and some rendering outputs and post work effects. 2D concept by one of my all time favorite artists Creature box, basically half of my gallery is inspired by their characters.

Step 01: Modeling

I started with a character concept by CreatureBox (they are one of my all time favorite artists). I start by creating simple blockouts of the different shapes and parts in MODO. I continued to add the components but I didn't focus too much on the details, which came later; it was much more important to get the proportions correct and closely follow the concept. I kept symmetry turned on as I find it easier to model with it on and then break symmetry once I had finished the modeling and get to the posing stage. With the bulk of the character modeled I moved on to adding the little details such as the grill in his nose and his spine. The next bit of modeling was a lot of fun because the concept sketch only has the front view; this meant I could give my imagination free reign to design the back of the bot. I added parts and details that fit with the look and feel of the original concept but also added my own little touch.

步驟01：建模

我開始用CreatureBox的字符概念（他們是我最喜歡的藝術(shù)家之一）。 我開始在MODO中創(chuàng)建不同形狀和部分的簡單塊。 我繼續(xù)添加組件，但我沒有關(guān)注太多的細(xì)節(jié)， 更重要的是獲得正確的比例，并緊跟這個概念。 我保持對稱開啟，因?yàn)槲野l(fā)現(xiàn)它更容易模型，然后打破對稱性一旦我完成了建模，并達(dá)到擺姿勢的階段。 隨著模型的大部分，我移動到添加小細(xì)節(jié)，如他的鼻子和他的脊椎。 下一步的建模是很有趣的，因?yàn)楦拍畈輬D只有前視圖; 這意味著我可以用我的想象力設(shè)計機(jī)器人的背面。 我添加了適合原始概念的外觀和感覺的部分和細(xì)節(jié)，但也添加了我自己的小觸摸。

Step 02: Look development and color

With all the modeling done I moved on to posing Robocat and connecting the free floating parts to the body. I decided it would be much easier to model these parts once I had finished posing the main parts such as the arms. I also started testing different lighting option to find the mood for the final image.

As the concept is in black and white I was able to use my imagination to shade and color the character. I tried different colors but found that yellow really made the character pop, so I went with yellow and orange shades. I also made a base for him to stand on.

步驟02：看看發(fā)展和顏色

隨著所有的建模完成我移動到構(gòu)成Robocat和連接自由浮動部分到身體。 我決定，一旦我完成了主要部分，如手臂，這將是更容易模型這些部分。 我也開始測試不同的照明選項(xiàng)來找到最終圖像的心情。

由于這個概念是黑白的，我能夠使用我的想象力來遮蔽和著色角色。 我嘗試不同的顏色，但發(fā)現(xiàn)黃色真的使人物流行，所以我使用黃色和橙色色調(diào)。 我也為他做了一個基地。

Step 03: Finalizing details and pose

For this step I finished all the little details and refined the pose. I added some back pipes and also remodeled the base so that it matches the overall look of the model and original concept. I often go back and forth adding and deleting details on my models, I do this because I'm never 100% sure about which angle the final image will be taken from so I like to make sure that the model is finished and detailed from all angles.

步驟03：完成細(xì)節(jié)和姿勢

對于這一步，我完成了所有的小細(xì)節(jié)和完善姿勢。 我添加了一些背管，也重塑了基地，使其匹配的模型和原始概念的整體外觀。 我經(jīng)常來回地添加和刪除模型上的細(xì)節(jié)，我這樣做是因?yàn)槲矣肋h(yuǎn)不會100％確定最終的圖像將從哪個角度，所以我喜歡確保模型完成和詳細(xì)從所有角度。

Step 04: Light setup

Lighting setup is an important part of any piece of work. To light this scene I placed two area lights on the bot's left and right, one directional light on shining from the left side to highlight a focus point on the eye, and finally, one spot light with volumetric from the back to give him a soft rim light with a few light rays. This helps to add some depth and separate between the background and foreground.

步驟04：光設(shè)置

照明設(shè)置是任何工作的重要組成部分。 為了點(diǎn)亮這個場景，我在機(jī)器人的左右兩側(cè)放置兩個區(qū)域燈，一個定向燈從左側(cè)照射，以突出眼睛上的焦點(diǎn)，最后，一個點(diǎn)光從后面給他一個柔軟的 邊緣光和幾光線。 這有助于添加一些深度，并在背景和前景之間分離。

Step 05: Setting up shaders and materials

For this step I added materials and shading to the model. I did most of the parts with procedural texturing, I didn't bother with UVs. MODO is really great for this type of texturing. To make the dirt and scratches I used an AO map and set it on the edges with a darker color, this is a cheap hack but works fine in most cases.

步驟05：設(shè)置著色器和材質(zhì)

對于這一步，我向模型添加了材質(zhì)和陰影。 我做了大部分的程序紋理，我沒有計較UVs。 MODO真的偉大的這種類型的紋理。 為了讓它有污垢和劃痕我使用AO地圖，并設(shè)置在邊緣以更深的顏色，這是一個廉價的黑客，但在大多數(shù)情況下工作正常。

Step 06: Raw render

The final raw looks a bit washed out, which is fine for this stage because I try to get 60 to 70% of what I need for the raw render and then do some post work and tweak things. I did a few render passes (Color, AO, Material ID, and Shading Incidence). The depth was rendered in MODO with 1024 AA samples to get a clean result. This is one of my favorite steps to get stuck in to, I did the final color grade and added some extra punch to the image, as well as sharpen it a little bit and focused the light around the model.

步驟06：原始渲染

最后的原始外觀有點(diǎn)被洗掉了，這是對這個階段很好，因?yàn)槲以噲D獲得60％到70％的我需要的原始渲染，然后做一些后期工作和調(diào)整的東西。 我做了幾個渲染通行證（顏色，AO，材料ID和陰影發(fā)生率）。 深度在具有1024個AA樣本的MODO中呈現(xiàn)以獲得干凈的結(jié)果。 這是我最喜歡的步驟之一，我做了最后的顏色等級，并增加了一些額外的打孔的圖像，以及銳化一點(diǎn)，聚焦在模型周圍的光。

Step 07: Adding the last details

Looking at the results of the previous step everything looks great but is there more that I could add? I realized that Robocat looked too clean for a robot so I decided to add some dirt and scratches here and there on the model to add some realism; although not too much as I didn't want to overdo it. With the dirt added I was happy with the finished result. Thank you for reading this making of and I hope it has been useful to you.

步驟07：添加最后的細(xì)節(jié)

看看上一步的結(jié)果一切看起來很棒，但還有更多，我可以添加？ 我意識到Robocat看起來太干凈的機(jī)器人，所以我決定在這里和那里添加一些污垢和劃痕在模型上添加一些現(xiàn)實(shí)主義; 雖然沒有太多，我不想過度。 隨著污垢添加，我很高興與完成的結(jié)果。 謝謝你閱讀這個作品，我希望它對你有用。
