雾天摄像头

这是一款基于道具的相机，由分层平面构成，用于营造浓密、斑驳或平滑的雾气、烟雾、水下阴霾、低云或沙尘暴效果。套件内含 29 种材质，包括颜色叠加层和不同密度的材质。还配有适用于 Iray 和 3Delight 的深度渲染材质，可辅助制作图像编辑用的蒙版。该套件包含灰色渐变 HDR 渲染设置，能快速生成环境光照效果。 将材质应用于雾气道具，而非相机。 可同时使用多个雾气道具。 除预设外，您还可以调整 Z 轴（雾气道具深度）以控制密度，也可手动调整表面效果。 与现实中的雾气类似，光线方向也会影响雾气的密度。 在大多数宣传片中，雾气道具的尺寸刚好能覆盖主要人物和道具的深度范围。 使用广角变形功能来适应相机的焦距。 雾气会自然产生景深和一些光晕效果，但若开启这些效果（尤其是在水下场景中），能进一步增强景深感和戏剧性效果。 该火车宣传片使用了两个雾气道具，并对其进行了不同角度的缩放和设置。 选择深度渲染的渲染设置和深度蒙版材质，这些材质可用作图像编辑时的蒙版。该材质预设没有折射效果，因此在较小场景中可能会看到平面。如果出现这种情况，可以使用景深效果或在后期处理中模糊图像。 欲了解更多提示，请参阅自述文件，并前往论坛商业版块参与产品讨论

This is a prop-based camera built from layered planes for creating thick, patchy or smooth fog; smoke; underwater haze; low clouds; or sandstorms. There are 29 materials including color overlays, and various densities. There is a depth render material for Iray and 3Delight to assist in making masks for image editing. This set includes a gray gradient HDR render setting that provides fast ambient lighting. Apply materials to the fog prop, not camera. Multiple fog props can be used at one time. Beyond the presets you can scale the Z axis (Fog Prop Depth) to control density or adjust surfaces manually. Similar to real fog, light direction can also affect density. With most of the promos, the fog prop was scaled just enough to encompass the depth of the main figures and props. Use the widen angle morph to fit the camera’s focal length. The fog naturally creates DOF and some bloom effects - but turning these on, especially for underwater scenes, can create even more depth and drama. The train promo uses two fog props, scaled and set at different angles. Choose the render setting and depth mask material for depth renders, which can be used as masks in image editing. This material preset has no refraction so the planes may show on smaller scenes. If this occurs, use DOF or blur the image in post work.
