本節(jié)匯寶盆為大家?guī)淼?dmax教程：關(guān)于室內(nèi)HDRI真實燈光的一篇簡單教程

PREPARATION | 預(yù)置

For all my projects I set my gamma for LWWF(Linear Workflow) to get a correct brightness and because I want to do post production on my image.
· 個人的一個作圖習慣 - 把gamma設(shè)置成LWWF(Linear Workflow.線性流程)以獲得最真實的光感，減少后期工作。

MODELING | 建模

In this scene I used ready made models for accessaries, so I just modeled the wall, floor, window object using basic edit poly. And I created a simple decorative cloth model in Clo3d 2011.
· 場景里基本使用的都是外部引入的家具擺設(shè)模型，只需要建門窗地板，然后要提到的是用Clo3d 2011(三維服裝軟件)做了個簡單的衣服模型。

Fix model for camera view.
· 視角如下

Book case for reflection on the mirror.
· 鏡子反射用到的書柜

Cloth made in clo3d 2011 and the floor made only from a simple box.
· clo3d 2011做的衣服模型，地板只是個簡單的盒子

LIGHTING | 打光

As I said before, in this scene I am using HDRI lighting with Vraylight Dome+HDRI map. You can see my method in the image below.
· 場景用到的是HDRI 燈光和Vray燈光頂（Vraylight Dome）+ HDRI貼圖，如下圖所示。

You only have to set the mapping type to spherical, horiz,. rotation to control the sum beam direction, and gamma to set a correct GI, sun and strong shadow shape.
· 只需把設(shè)貼圖設(shè)置成球形水平旋轉(zhuǎn)來控制光束的大方向，把gamma設(shè)置成正確的GI，太陽光和重陰影形狀。

This is the simulation using different gamma values:
· 下面是不同gamma值下的效果。

Increased gamma can make a soft shadow effect and weak sun lighting. Decreased gamma can make the shadow look sharpen and strong sun lighting.
· 較高的gamma值能達到柔和的光影效果，而較低的光影對比更強烈。

Of course it is not a fixed setting. Different scenes require you to set different gamma values and also different horiz. rotation to get the correct lighting in your scene.
· 當然這不是唯一的參數(shù)設(shè)置，對于不同場景要靈活運用不同的gamma值和不同的水平旋轉(zhuǎn)來達到最佳的光影效果。

CAMERA SETTINGS | 相機設(shè)定
Just simple setting for my vrayphysical camera.
· 以下是vray物理相機的簡單參數(shù)

MATERIAL AND TEXTURING

There are a lot of advanced materials that I use in the simple scene. I only use standard method color selector to set the diffuse and reflect properties.
· 在這個簡單的場景里有很多高級材質(zhì)設(shè)置，在反射上只用到了基本的方法，沒什么特別的。

Wood floor · 地板

Red Leather · 紅皮革

Fabric · 布料

RENDER PRESET | 渲染預(yù)設(shè)
Here are my render preset settings:
· 以下是這里用到的渲染預(yù)設(shè)

And this is the final raw rendered image:
· 下面是無后期的渲染圖

Z-depth map image · 深度圖

Reflection map image · 反射圖

POST PRODUCTION | 后期
In this process I only use a simple technique for post production. I like natural colors in my rendered image.
· 這一步用了個簡單的后期技巧，我喜歡做很自然的顏色。

1. Color correction using color balance and curves and then add little bit of diffuse glow.
· 用色彩平衡和曲線來做顏色校正，加入了一點發(fā)散的光暈。
