i have Subsurface that found is UE5‘s’ bug？

[bobjie1314]

1.创建次表面材质

2.创建空场景设置灯光
点光源

聚光灯

3.放置物体并附上次表面材质 环境中的位置 0,0,0

问题：
我调整不透明度 ，为什么物件还是这样？光线量没有变少？

1. Create a subsurface material
2. Create an empty scene and set the lights
3. Place the object and attach the subsurface material Position in the environment 0,0,0

question:
I adjust the opacity, why is the object still like this? The amount of light has not decreased?
