适用于 Iray 和 3Delight 的 “雾之上” 材质包

适用于 Iray 和 3Delight 的这款道具拥有诸多材质预设，可控制颜色、密度，以及烟雾的扩散程度和对比度。用户能轻松营造出不同氛围，从平滑、起伏、浓重到轻盈、空灵、零星不一而足。它用途广泛，能满足您的创作需求。您可以调整道具倾斜度，营造出烟雾墙效果；也可以将其翻转，使烟雾聚集在天花板上。借助随附的 D-Former 工具，您还能改变烟雾形状，将其提升成波浪状，既可缩小规模以适应坩埚模型，也能放大规模以覆盖山顶墓地。 3Delight 版本的道具预设比 Iray 版更多，还能通过简单操作生成体积光（神光）效果，但这会增加渲染时间。两款道具对光线都十分敏感，能捕捉并散射光线，营造出更逼真的烟雾效果。若使用 3Delight 中的环境遮挡功能，建议搭配 Age Of Armour 的 Advanced Ambient Light 插件，其排除表面的功能能显著提升渲染速度，而非依赖 UberEnvironment2。Iray 版道具与环境光配合效果最佳，尤其是基于 HDR 的灯光效果。 若想查看道具的工作视图，请切换至绘图样式：线框着色。 说明文档中附有链接，指导用户如何自定义超出预设范围的表面材质，详情请参阅“ReadMe”文件

This prop for Iray and 3Delight has many material presets that control color, density, as well as the puff scale and contrast. It’s easy to change the mood, go from smooth, undulating, and heavy to light, airy and patchy. It’s versatile to fit your story, this prop can be tilted to create a wall of fog or flipped to create smoke collecting on the ceiling. Change the shape using the included D-Former to lift the fog into a swell, which can be scaled small to fit a cauldron or large to encompass a cemetery on a hill. The 3Delight prop has many more presets than the Iray version and can be adjusted to create volumetric effects (God rays) with the flip of a switch. This will increase render times. Both versions are sensitive to light, as both catch and scatter light for more realism to real fog. For Ambient Occlusion in 3Delight, you will experience faster renders using Age Of Armour's Advanced Ambient Light, with it’s ability to exclude surfaces, rather than using UberEnvironment2. The Iray prop works best with ambient light, especially HDR based lights. To see the prop in working view switch to drawing style: Wire Frame Shaded. Instructions are included with a link on how to customize surfaces beyond the presets, see the ReadMe.
