+# 前言
+在UE5.1发现了若干新节点感觉对后处理描边有很大的作用。
+![[MultiDraw_OutlineMaterial.png]]
+
+
+UE单位为cm，理论上范围为10cm~10000cm（1000m）。假设标准的角色身高为180cm（110~200cm变化比较轻微）定义一个标准数StandardCharacterHeight。
+
+经过观察`10~StandardCharacterHeight * 2`范围适合使用CurveTexture，超过StandardCharacterHeight * 2的区域基本是一个线性区间。
+{360 0.5} {10000 0.018}
+
+斜率 k = 0.0005/1cm
+
+
+
+x轴 10=>0 , 180 => 1
+    -18=0 , -0.018
+
+    15      20      25      30      40      60      100 
+    -12     -9      -7.2    -6      -4.5    -3      -1.8
+
+
+    0.33    0.25    0.2     0.1666  0.125   0.08333  0.05
+    0.667   0.75    0.8     0.83334 0.875   0.91666  0.95
+
+
+最终斜率使用0.002
+
+half invLerp(half from, half to, half value) 
+{
+    return (value - from) / (to - from);
+}
+half invLerpClamp(half from, half to, half value)
+{
+    return saturate(invLerp(from,to,value));
+}
+// full control remap, but slower
+half remap(half origFrom, half origTo, half targetFrom, half targetTo, half value)
+{
+    half rel = invLerp(origFrom, origTo, value);
+    return lerp(targetFrom, targetTo, rel);
+}
+

+
+以下去本人设置的曲线：![[MultiDraw_OutlineCurve.png]]]
