Multi coated lens shader

#1

Hi everyone, I have an upcoming project that requires a nice multi coated lens shader, where it have a nice tint of color from a certain viewing angle.

Anyone have any tips regarding this shader? Any help is much appreciated! Thank you!

Software? In Max you could use a multicolor ramp mapped to the viewing angle (normal), placed in the reflection and specular color of your glass material.

What renderer are you using?

I know maxwell can do thin coating like this

I use maya with Mental Ray / Vray depends on which gives me a good result.

I was thinking along the line of adding ramps dependent on viewing angles in maya as well, but I am curious if there r shaders already built for this purpose? Or any physical shader that are built for this phenomena?

If you like iray, you can get a thin film coating material here:

I havent tried it, but from what i’ve seen results looks decent.

There might not be any built in shaders in Maya for that purpose, (ones that aren’t hidden anyway), but you can download some custom MR shaders - Check my last post here -

Hmm, looks like the tektoshoot website has been down for a while…I haven’t been able to find a link for it anywhere. I have the T2S Illumination shader, not sure if its okay to distribute it though.

Also, you will probably need to model different lens elements to get multiple reflections and refractions. A good environment map will also be key to making the shader look good.
