Weird lumen reflections

Hello all,

Anyone knows why do I keep getting these weird angled reflections on my glass material?

That looks like refraction. Generally you don’t want to use the refraction on thin, flat planes like glass. Even though technically real windows do refract light as the light enters the glass, upon exiting the glass it refracts is back to face the same direction as the original ray, resulting in essentially no visible refraction. IRL, refraction is often only particularly noticeable of curved surfaces, because the curvature causes the ray to exit the medium still going a different direction than it entered. Glass in game engines is often 2 dimensional and refraction is often approximate, so it can’t achieve this properly (without Raytraced refraction, anyway).

It was exactly that, I just needed to get rid of the refraction value on the material graph.

Thank you very much for your explanation!
