How to Make a Glass Material in UE5
Glass is less a texture than a shading setup: its identity comes from translucency, fresnel reflection and near-zero roughness. In UE5 that means the material settings matter as much as any map you plug in.
Channel by channel
Base color
Nearly black-to-neutral with a faint tint (green for cheap float glass, blue-grey for architectural). In a translucent material the "color" mostly comes from Opacity and tint, not albedo.
Roughness
Very low, 0.0–0.1 — but real glass carries smudges and dust, so a faint fingerprint variation map at 0.05–0.25 sells it far better than a constant 0.
Metallic
0.0 — glass is a dielectric whose strong reflections come from fresnel, not the metallic channel.
Normal
Flat for panes; slight waviness for old windows; strong refraction-driving normals only for privacy/patterned glass.
The hand-building tip that matters
Use the Translucent blend mode with Surface ForwardShading (or Thin Translucent for realistic tinted panes), keep Opacity around 0.1–0.3, and let a Fresnel node boost reflectivity at grazing angles — that fresnel falloff is 90% of what makes glass read as glass.
