How Reflector makes the ground realize the effect of Gaussian blur

Questions
1

I hope to get the effect of Figure 1, which makes the smooth ground highlight more realistic, but the final effect is the appearance of Figure 2, which is very strange. I tried to add another layer of mask above the ground and set the opacity to 0.95, but the final effect looked fake (as Figure 3). This problem has taken me a lot of time. I hope someone can help me. Thank you.

In addition，I found that when using Reflector, it seems that its reflection to Sprite is not normal. In Figure 2 and figure 3, the red label uses Sprite. The projection of Sprite can only be seen at some angles, and the projection direction is not right. Is this a bug of Reflector? How to solve this problem? Thank you.

This can only be achieved with a custom shader. Meaning you have to overwrite the following default shader of Reflector:

I don’t think this use case was ever tested so far. However, there are related scaling issue with THREE.Points, see THREE.Points sprites are not scaled correctly by THREE.Water shader · Issue #11889 · mrdoob/three.js · GitHub.

Thank you very much for your reply. About whether overwrite default shader of Reflector can provide more help, I shall be very grateful. I’m not good at it.
