Car tail lights color

[CG_Utopian]

Hi,

I am working on a car tail lights currently but what i am not able to achieve is to maintain the color of the lights through the outer red glass. the inner lights are yellowish but they look perfect red through the outer glass. i would like to know if there's something i can do to the outer cover material so it doesn't affect the color of the lights.

what i am trying to achieve is something like in the attached example. but instead i always get absolute red lights and the yellow is completely gone.

Thanks

the only way Ive done that before is to basically cut out the part that is to be amber and either tint it amber or clear with amber lights behind it. Or Im not sure but you might be able to use IPR and tint the amber light till it matches what you want with altering blue or green channels.

Did a quick test, works fine on my side.
Is the geometry accurate to the real car lens, I think they are made thinner and use fresnel lensing in those sections.
Are you using fog color to make the glass red?
What are your settings?
Increasing the yellow lights multiplier will "punch" through the fog color.

The attached image is the tail light i am trying to render. It is the outer red cover and then another layer of blurry glass then the LEDs under it. So the light has to go through 2 layers of glass. The way i am doing it is white blurred glass for the inner part and red clear glass for the outer shell and i am using orange/yellow vray light material for the light source. And yes i am controlling the color of the glass with the fog color.

And could you please explain what you mean by "fresnel lensing" ?

Problem solved.

For whoever could need it in the future, just had to go really low on the fog multiplier ..

Looks good!
Did you assign a light material to the LEDs behind the blurry glass of the two "arrows"? Which color are they, yellow?

No, the original mesh did not give the right light behaviour so i made a "custom" mesh with gradient applied to it to be the light the source and give this fading effect .. and yes the light source is yellow ..
