Marble

The Marble node is a procedural texture that can be used to create marble-like noise. It is similar to a turbulence texture but more fine-tuned to create marble-like patterns.
大理石节点是程序纹理，可用于创建类似大理石的噪声。它类似于湍流纹理，但经过更精细的调整，可以创造出大理石般的图案。

HOW TO USE

如何使用
Open the Node editor and prepare the setup as you see in the image below. The Marble and Gradient Nodes are connected to the diffuse channel of the material. A Gradient node is used because Marble has no color definition by default. A Transform node is connected to Marble’s transform slot to adjust the Marble textures PSR values.
打开 Node 编辑器，准备如下图所示的设置。大理石和梯度节点连接到漫反射通道的材料。使用渐变节点是因为默认情况下大理石没有颜色定义。转换节点连接到大理石的转换槽以调整大理石纹理 PSR 值。
