科幻場(chǎng)景制作

在本教程中，我將向您展示如何創(chuàng)建一個(gè)快速的幻想情緒概念，從最初的概念草圖開(kāi)始，使用SketchUp并解釋顏色和紋理的使用步驟。

In this tutorial I'm going to show you how to create a quick fantasy mood concept, starting from the initial concept sketch using SketchUp and explaining the use of colors and textures steps-by-step.

第1步：SketchUp（阻擋構(gòu)圖）和基本顏色

這個(gè)概念的第一步是使用3D程序SketchUp來(lái)獲得一些形狀和塊作為構(gòu)圖的基礎(chǔ)。要在SketchUp中繪制簡(jiǎn)單的矩形形狀，只需單擊工具欄上的圓形圖標(biāo)上的下拉框，然后選擇矩形。您可以通過(guò)單擊畫布上的第一個(gè)角落來(lái)創(chuàng)建矩形，然后您可以設(shè)置第二個(gè)角落來(lái)創(chuàng)建矩形。然后，您可以使用“推/拉”工具將矩形拉成3D形狀。線條工具允許您以相同的方式繪制其他形狀。

然后，我使用渲染來(lái)設(shè)置一些情緒，玩弄燈光和陰影。您可以使用“陰影”工具欄（“視圖”>“陰影”）)在SketchUp中完成此操作。

一旦我對(duì)我的作品感到滿意，我將文件導(dǎo)出到Photoshop中，進(jìn)入文件>導(dǎo)出> 2D圖形，這將彈出一個(gè)對(duì)話框的選項(xiàng)，并保存為JPEG。在Photoshop中，我開(kāi)始用顏色和柔光的漸變工具放下一些基本顏色。，這些微妙的色調(diào)將是情緒的主要調(diào)色板。

Step 1: SketchUp (blocking composition) and base colors

The very first step for this concept is to use the 3D program SketchUp to obtain some shapes and blocks as a base for the composition. To draw a simple rectangle shape in SketchUp simply click on the dropdown box on the circle icon on the toolbar and select Rectangle. You can then create the rectangle by clicking onto the canvas to anchor the first corner then you can set your second corner to create the rectangle. You can then use the Push/Pull Tool to pull the rectangle up into a 3D shape. The Line tool allows you to draw other shapes in the same way.

Then, I use a render to set some mood, playing around with lights and shadows. You can do this in SketchUp using the Shadows Toolbar (View > Shadows).

Once I am satisfied with my composition, I export the file into Photoshop, go to File > Export > 2D Graphic which will bring up a dialogue box of options and save as a JPEG. In Photoshop I start to put down some base colors with the Gradient tool in color and Soft Light ? these subtle tones will be the main color palette for the mood.

第2步：紋理基地

一旦設(shè)置了基本顏色，我就開(kāi)始為整個(gè)場(chǎng)景添加紋理。我在軟光和普通模式下添加這些紋理，使用橡皮擦工具和設(shè)置為“轉(zhuǎn)移”選項(xiàng)的軟筆刷（在筆刷筆觸的兩端創(chuàng)建淡入淡出效果），并在必要時(shí)擦除部分紋理。然后拿一個(gè)紋理筆刷，把這兩種技術(shù)混合在一起。最后，我勾勒出一排云彩，大致勾勒出天空。

Step 2: Texturing base

Once the base colors are set I start to add textures to the entire scene. I add in theses textures in Soft Light and Normal mode, using the Eraser tool and a soft brush set to the Transfer option (creates a fade on both ends of your brush stroke) and erase some parts of the textures where necessary. Then taking a texture brush, I mix the two techniques together. Finally, I trace a line of clouds and roughly sketch out the sky.

第三步:背景、天空和細(xì)節(jié)

我現(xiàn)在開(kāi)始在背景上非常密集地工作，在山和天空中添加細(xì)節(jié)，通過(guò)在柔和的光模式中添加陰影來(lái)加強(qiáng)光線，并在正常模式下增加(繪畫)紋理。

我還增加了天空的大氣氣氛（在正常模式下使用主動(dòng)轉(zhuǎn)移選項(xiàng)進(jìn)行繪制），以給予更多的深度和移動(dòng)到場(chǎng)景。

Step 3: Background, sky mood and details

I now begin to work very intensively on the background, adding little details to the mountains and sky, strengthening the light by adding shades in Soft Light mode and increasing (painting over) the texture on a Normal mode.

I also add the atmospheric mood of the sky (painting in normal mode with active transfer option) to give more depth and movement to the scene.

第四步：細(xì)節(jié)和對(duì)比

我用Curves面具進(jìn)一步強(qiáng)調(diào)光線和對(duì)比度，以增加表征場(chǎng)景的情緒。 下一步是細(xì)化整個(gè)環(huán)境，所以我繼續(xù)在普通模式下使用畫筆，在前景中繪制所有細(xì)節(jié)。

Step 4: Details and contrasts

I accentuate the light and contrast further with a Curves mask to increase the mood which characterizes the scene. The next step is to refine the entire environment, so I proceed using a brush in Normal mode, painting all the details in the foreground.

第5步：字符

我走到人物素描上，首先通過(guò)描繪粗糙的線條，得到一個(gè)確定的黑色形狀（如輪廓）。 此時(shí)，我開(kāi)始使用“正常”，“顏色”和“主動(dòng)轉(zhuǎn)移”來(lái)繪制體積，以更好地控制畫筆。

然后我開(kāi)始用Lighten圖層模式對(duì)角色進(jìn)行阻擋，添加陰影來(lái)匹配角色的顏色和環(huán)境情緒。 最后，我在裝甲的外部添加一些光點(diǎn)，以便與角色形成更多的對(duì)比。

Step 5: Character

I move onto the character sketch, by tracing out the rough lines first I obtain a defined black shape (like a silhouette). At this point I start to paint the volumes with Normal, Color and Active Transfer to have a better control on the brush.

Then I began blocking in the character with the Lighten layer mode on, I add shade to match the character?s color with the environment mood. Finally I add some light spots on the outer parts of the armor to give more contrast to the character.

步驟6:細(xì)節(jié)和最后的觸摸

在這一點(diǎn)上，我給場(chǎng)景添加了一些細(xì)節(jié)，來(lái)增強(qiáng)活力。我畫了從柱子出來(lái)的燈光和光線，突出場(chǎng)景的焦點(diǎn)，我在這里畫一些石頭(用濾鏡模糊它們)，來(lái)增加一些運(yùn)動(dòng)。

最后一步是通過(guò)使用銳化濾鏡(智能銳化)來(lái)增加環(huán)境的焦點(diǎn)，增加了很多關(guān)于柱子上的裂縫的細(xì)節(jié)，并增加了與所有曲線的對(duì)比度。

Step 6: Details and finishing touch

At this point I add some details to the scene to give dynamism. I paint the lights and rays that come out of the pillars to highlight the focal point of the scene and I paint some stones here and there (blurring them with filters) to add some movement.

The final step is to add contrast the focal points of the environment by using the Sharpen filter (Smart Sharpen), increasing a lot the details of the cracks on the pillars, and adding further contrast to everything with a Curves level.
