Cellular water — source scene recovered 这节课换成 Cellular 水面，然后把上一节的线性条纹少量混回来。先学灰度图案，再学蓝色映射，最后加动画。以下数值来自本机 [本机资料路径] 的实际读取；它是包含后续水滴的保存版本，不代表视频每个中间时刻。

原工程未修改，SHA-256 前后相同。学习副本已通过 Max 的 Save As 保存。下方另有水面观察镜头副本和三帧渲染。水面 101 帧已完成；雨滴考核仍未完成。
1 · Create the surface Plane 名称 Wave ，Length / Width = 400 cm ，Length Segs / Width Segs = 1 / 1 ，Z = 5 cm 。保留 Generate Mapping Coords。源场景还有 LightRoom、两个 Arnold Lights 和 Sphere001 水滴；没有保存 Camera 对象，不能声称恢复了老师镜头。
2 · Make the cell pattern 在 Slate 创建 Cellular #36 ，复制为 #37 。两者 Size = 0.2 ，Spread = 0.5 ，Fractal = Off，Coordinates 使用 Explicit Map Channel 1 。#37 的 Offset = (0.5, 0.5, 0.2)，W Angle = 90°（Frame 0）。黑色中心和亮边界形成不规则区域。两个方向叠加，使水面不只是一排重复图案。
3 · Composite #38 Layer Map Blend Mode Opacity 1 Cellular #36 Normal 100% 2 Cellular #37 Overlay 100% 3 Smoke #39 Multiply 70%
Smoke #39 使用 Explicit Map Channel 1、Size 0.2、Iterations 5、Exponent 1.5。Multiply 层把部分区域压暗。练习时先关闭 Auto Key，把这一层 Opacity 改为 0，观察差异，然后恢复 70。
4 · Add fine details Noise #40 → Source Map of Gradient Ramp #41 。#41 用 Mapped，把 Noise 的灰度重新分配为多条明暗带。源工程保存的 #41 Noise Amount 是 0.12 ，Size = 0.8 ；视频中途出现的 0.1 不等于最后保存值。
Composite Layer 1 Layer 2 Layer 2 Opacity #42 #38 / Normal #41 / Linear Dodge 5% #44 #43 / Normal #30 / Screen 10%
#42 的细节只混 5%，不要用课堂试调时的 100% 替代最终值。#44 的 #30 是上一节线性水面，不是新建的空白贴图。
5 · Turn grayscale into blue #36 + #37 + #39 → Composite #38 ─┐

Water → Emission Color Water 是 Arnold Standard Surface 。Base = 0，Specular = 0，Emission = 0.5。蓝色来自 Emission Color 的节点链。此路径不能单独证明有几何起伏或 Displacement。
6 · Animate the texture 下面是实际 Controller 的关键帧，不是仅凭截图猜的数值。建议先保存副本，在 Frame 0 建第一个值，开启 Auto Key，移到 Frame 100 设置第二个值，再关闭 Auto Key。在 Curve Editor 核对 Tangents。

Offset 让纹理采样位置改变；Phase 让噪波形态演变。它们不移动 Plane。Cellular #36 在 Frame 18 的 W Offset 实读 0.054，在 Frame 66 是 0.198，在 Frame 100 是 0.3，与线性变化一致。
Exact saved-node values 展开查看原生属性。数值保留浮点精度；颜色是源工程存储的通道值，不是从截图吸取的屏幕颜色。Gradient Ramp 的第一个/第二个端点 Position 固定为 0/100，未暴露 Position 属性时按端点标明。不要把这些色标的列表顺序当位置排序。
