INTRODUCTION | 介绍

Here will explain very simple practice interior render with HDRI lighting

· 关于室内HDRI真实灯光的一篇简单教程

PREPARATION | 预置

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.

· 个人的一个作图习惯 - 把gamma设置成LWWF(Linear Workflow.线性流程)以获得最真实的光感，减少后期工作。

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.

· 场景里基本使用的都是外部引入的家具摆设模型，只需要建门窗地板，然后要提到的是用Clo3d 2011(三维服装软件)做了个简单的衣服模型。

Fix model for camera view.

· 视角如下

Book case for reflection on the mirror.

· 镜子反射用到的书柜

Cloth made in clo3d 2011 and the floor made only from a simple box.

· clo3d 2011做的衣服模型，地板只是个简单的盒子

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.

· 场景用到的是HDRI 灯光和Vray灯光顶(Vraylight Dome)+ HDRI贴图，如下图所示。

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.

· 只需把设贴图设置成球形水平旋转来控制光束的大方向，把gamma设置成正确的GI，太阳光和重阴影形状。

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.

· 较高的gamma值能达到柔和的光影效果，而较低的光影对比更强烈。

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.

· 当然这不是唯一的参数设置，对于不同场景要灵活运用不同的gamma值和不同的水平旋转来达到最佳的光影效果。

CAMERA SETTINGS | 相机设定

Just simple setting for my vrayphysical camera.

· 以下是vray物理相机的简单参数

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.

· 在这个简单的场景里有很多高级材质设置，在反射上只用到了基本的方法，没什么特别的。

Wood floor · 地板

Red Leather · 红皮革

Fabric · 布料

RENDER PRESET | 渲染预设

Here are my render preset settings:

· 以下是这里用到的渲染预设

And this is the final raw rendered image:

· 下面是无后期的渲染图

Z-depth map image · 深度图

Reflection map image · 反射图

POST PRODUCTION | 后期

In this process I only use a simple technique for post production. I like natural colors in my rendered image.

· 这一步用了个简单的后期技巧，我喜欢做很自然的颜色。

1. Color correction using color balance and curves and then add little bit of diffuse glow.

· 用色彩平衡和曲线来做颜色校正，加入了一点发散的光晕。

2. Blend with a reflection map

· 与反射贴图混合

3. Add a Depth Of Filed effect using a z-depth map

· 用深度图增强效果

4. Chromatic Aberration · 色彩调节

FINAL RENDER RESULT | 最终图

That's all of the post production and this is the final result:
