Light Tracer
Light Tracer此角色用light tracing渲染，用skylight 和一个spotlight照明。
Light Tracer对明亮的场景（比如室外）提供真实的软阴影和颜色影响。
不同radiosity的是，Light Tracer不需要按照物理精度建模，所以能更简单的建立场景。
Light tracing和skylight渲染的室外场景。
小技巧：室内场景也可以用light tracing，但radiosity往往是更好的选择！预览light tracing的效果：1，为了快速预览light tracing的效果，请降低Rays/Sample 和Filter Size的值，结果将会得到有麻点的效果。
2，另一种方法是确定Adaptive Undersampling是在打开状态，设置Initial Sample Spacing的值等于Subdivide Down To的值。
这样将会给出一个粗糙但是快速的light tracing的效果。
运用Light Tracer的其他技巧：1，为了改善渲染时间，请在Object Properties dialog中将那些对最终效果没有很大影响的物体的light tracing或radiosity solving关闭。
（当然你也能在Advanced Lighting Override material中对那些有重大影响的物体进行设置。
）2，对adaptive undersampling的设置进行试验，因为其对你的场景中的light tracing的区域起约束作用。
3，为了增强颜色的影响，请加大Bounces 和Color Bleed的值，通常来说Color Bleed是一种微妙的效果。
4，如果你的场景中有透明物体（玻璃等），请将Bounces的值设置为大于0。
（但是你要意识到这样会增加渲染时间。
）5，如果你的主光源为天空光，但是你的场景中需要高光，增加第二个光源！：例如，一个和天空光一致的直接光，确定其阴影是打开的，然后在Advanced Effects rollout中关闭其对Diffuse的影响！6，Set Key filters are not taken into account when you animate Light Tracer settings. If you wish to use Set Key to create keys for animating the Light Tracer parameters, SHIFT+right-click the spinner to create those keys.（这是关于动画的，我就不熟悉了）重要！！！：如果你要用一个贴图来作为天空光，请在图象编辑软件中将其彻底的模糊后再使用！这将消除贴图中象素的不一致。

整合Lightfinder 技术的网络摄像机是低光照条件下室内和室外监测的理想解决方案， 特别是当用 户要求视频中有色彩信息以加强物体的辨认和识别时。 与传统具有日夜转换功能的摄像机在光线 较暗的环境下转换为黑白模式不同， 整合Lightfinder 技术的摄像机即使在光线非常暗的条件下也 能保留色彩。 在很多情况下， 带色彩的监测视频是成功识别的一个重要因素， 这种功能极大地增加了用户有效 识别人物、 车辆和事件的可能性。 这些摄像机在苛刻的视频监测应用中尤其有用， 它们可用于各种低光照应用中， 如停车场、 城市 监测、 校园和施工现场。 Lightfinder 技术可用于室外周边环境， 如发电厂 、 水处理厂 、 监狱， 以及铁 路监测。 在极低光照条件下 ， 比如晚间可能只有一个灯光的施工现场， 用户可为这些摄像机补充红 外照明装置， 但Lightfinder技术的高感光性使得这种补充在许多情况下变得不必要。
