Material Parametrization

材质参数化

This Node can be used to edit Node-based materials within the Node environment. Note however the difference to working directly with the material system’s Node. Since the process is only evaluated once per frame, no samples per image pixel can be calculated. This means that the use of Generators, e.g., for noises or gradients, won’t work as if these were to come straight from the material. This can be circumvented when texturing clones, for example, by using the distribution’s Ratio value to sample color generators themselves at different positions and then transfer these colors to the clones.

此 Node 可用于在 Node 环境中编辑基于 Node 的材质。然而，请注意与直接使用材质系统的 Node 的区别。因为这个过程每帧只评估一次，所以不能计算每个像素的采样值。这意味着使用发生器，例如，噪音或梯度，不会工作，如果这些是直接来自材质。这可以避免时纹理克隆，例如，使用分布的比率值取样颜色生成器本身在不同的位置，然后将这些颜色转移到克隆。
