Hi everybody, my question is about how to render a colored light behind a glass, avoiding the surface to become completely white and not of the color of the emitter. My aim is to simulate a BLUE LED BEHIND A GLASS DIFFUSER that light up a surface.

thank you, bye!

Hi Maurizio,

Generally this should work. Light(s) will go white when it gets saturated (too bright), especially if you have "saturate to white" up high in the Imager settings.
Don't forget that the light that shines through the glass will be classed as a caustic so you will need to use PT or PMC for best results.

Can you please post some screenshots or sample scene?

Thanks
Chris.
