Three.js Reflection Help

Hello, I'm looking for someone to assist me with creating a reflection effect such as Blur and Normal mapping in Three.js. I already have some existing code and assets that can be used to help me realize my objective. My goal is to ultimately make the reflection effect reusable, so I'm looking for someone to help me create something that I can use again and again. With their help, I'm confident I can create a 3D visualization that both looks realistic and has great potential for reuse in the future.
