Iray 灰尘效果插件

Iray Dust 是一套材质叠加层、贴花和大气效果的集合，可模拟空中的大型灰尘颗粒。这些材质叠加层适用于大多数已进行 UV 映射的模型，且不会破坏底层纹理。通过调整强度值和颜色，您可以微调叠加效果。若您的模型 UV 映射不当，或根本没有 UV 映射，您可以使用集成的 Iray 贴花节点。 大气效果是一个简单的拖放网格，适用于大多数照明场景。只需将其添加到场景中，然后点击渲染即可。 借助 Iray Dust，尽情展现那些粗犷的细节吧

Iray Dust is a collection of shader overlays, decals, and an atmospheric effect that replicates large dust particles in the air. The shader overlays are applicable to most UV'd models and will not destroy the texture underneath. Different strength values and colors allow you to tweak your overlay effect. If your model is UV'd strangely, or has no UV's at all, you can use the integrated Iray decal node. The Atmospheric effect is a simple drag and drop grid that works in most lighting scenarios. Simply add it to your scene and hit render. Bring out the gritty details with Iray Dust.
