I am making a low poly headlights for a car and I have made the inside of the lights from reflective surface (mixed ~90% glossy with diffuse and little bit of glass) but from a certain angle it's not reflecting at all and looks ugly and unrealistic: enter image description here

But from the front it looks ok: enter image description here

This is the geometry: enter image description here

Please help me create reflective material that reflects light correctly no matter from what angle I look.

  • $\begingroup$ I don't think it's the reflections that are off, I think it's the transmission. Can't be sure though. Have you tried separating the components of the material? See how it looks without the glas, or without the glossy? Also as a hint: I wouldn't use glass here, you won't see the difference and the transparent shader produces far less noise. $\endgroup$ – Frederik Steinmetz Mar 18 at 16:45
  • $\begingroup$ Even pure glossy doesn't have the right reflections. What should I use instead? And since the new denoiser is OP I will just render at 1000 samples and all the noise from the glass will be gone. $\endgroup$ – Benedicts Forester Mar 19 at 11:46

    $\begingroup$ If the reflections from a pure glossy shader seem off, make sure your reflected objects/BG isn't actually gray in that area. Happened to me often enough... $\endgroup$ – Frederik Steinmetz Mar 24 at 18:28
  • $\begingroup$ Oh, yea the world is completely gray. Thanks. $\endgroup$ – Benedicts Forester Mar 26 at 13:58
