Part I: Adjusting the GI settings 调整 GI 设置 Part II: Rendering with materials 带材质渲染 Part III: Rendering the final image 渲染最终图 Part IV: Post-processing the image 后期处理 Part I: Adjusting the GI settings Step 1. First render 第一次渲染 不开GI ? 1.1. Open the scene (which can be found here). 打开场景 1.2. Assign V-Ray as the current renderer. 指定V-Ray 为渲染器 ? Since the default V-Ray settings are not very well suited for a fast initial preview, well make a few quick adjustments before the first render. ?V-Ray 默认的设置并不是非常适合快速预览渲染效果，在第一次渲染之前，快速调整一下设置。 1.3. Check the Override mtl option in the Global switches rollout, click the button next to it and select a default VRayMtl material. 在全局开关选项卡中的全覆盖材质选项上点击，选择VrayMtl材质。 1.4. Set the Image sampler type to Fixed. 选择图像采样类型为固定 1.5. Set the resolution to 400 x 325.（shift+F 显示安全框） 选择最终输出图像大小为400×325 1.6. Set the Region size in the System rollout to 32 x 32 pixels. 在系统选项卡中，设定区域尺寸为32×32像素 1.7. Optionally, you can turn on the Frame stamp to print the render time on the image. 可选项：打开水印，显示渲染时间。 1.8. Render the scene: ?渲染场景 ? Step 2. GI preview 打开GI ?GI（全局光） 预览 2.1. Turn GI on from the Indirect illumination rollout. 在间接照明选项卡中打开GI 2.2. Select Light map as both the primary and secondary GI engine. 选择Brute force（1.46版本前称为Light map，1.5版本为Brute force）为第一GI 引擎，选择Light cache （灯光缓存）为第二GI 引擎 2.3. In the Light cache rollout, set the Subdivs to 500, since we want only a fast preview. Well return this to 1000 for the final rendering. 在Light cache （灯光缓存）卷展栏中，设置Subdivs 细分值为 500（如果机器性能差，可以设置得更低）。现在需要的是快速预览，所以值比较低。在最终渲染时，再把这个值设定为1000。 2.4. Set the Interp. samples of the light map to 5 for a faster rendering. 为了更快速的渲染，设定发光贴图的插值样本为5。 2.4. Turn on the Show calc phase option for the light map. 打开发光
