How to create a headlight glass material with Normal Map, adjustable color and transparency?

Hi everyone,

I’m currently working on a vehicle project in Unreal Engine and I need some help creating a material for the headlight glass .

I already have a Normal Map that shows the detailed structure of the headlight surface (see attached screenshot), and I’d like to build a material that:

  • uses this Normal Map correctly (with visible structure),
  • allows me to adjust the color (e.g. red for rear lights, white for front),
  • and ideally has some level of transparency or glass-like effect , like real vehicle headlights or taillights.

I tried both
Opaque and Translucent blend modes, but with Translucent I lose the detail from the Normal Map. With Opaque I can’t get any transparency.

I’ve attached two screenshots: one of my current Material Graph setup, and one of the Normal Map texture I’m using.

Could someone please explain (in a beginner-friendly way) how to structure the material nodes to achieve a proper headlight glass material with color and Normal Map detail?

Thanks in advance!
