infinity

[jelly]

Hello to all,
I should reproduce an inifinity mirror, I'll post some images to explain what I mean. Any suggestions are welcome.

I would need a plane that is mirror one one side and glass from the other ore any other cheat you could think of.
Thanks

Hi Jelly,
It should be fairly straightforward to create this effect if you follow the same basic principles as a real-world infinity mirror:

Here's an example-- I created a 5mm-thick pane of glass, with separate surfaces for the outside and inside polys. The far back wall is a mirror shader (Glossy Material.) The outside glass is just a typical Specular Material glass shader. The inside glass is using a material mixer to combine the typical glass (Spec) material with a mirror (Glossy) material. The ratio of the spec-glossy mix here determines the strength of the "infinity" effect. Also, you can adjust the transmission amount in the Spec material to further refine the look (ie, creates a "smoked glass" look.)

Here's another angle, showing how it looks in a brighter environment:

Hope that helps!

Hello, it helped to create the effect, though it only works with bright objects (lights). I would need it to have the same effect with any object inside the "box". In my case probably marble cylinders. They are barely visible, if I try to light them up i only see the lights and a vague ghosty silouette of my objects.
This should be at the entrance of a restaurant in a daylight environment. I'm unable to let it work

This is where I got so far, just a detail of the full rendering.

Looking good, Jelly! Yeah the thing to remember about the effect is that even in the real world, the ambient light entering into the mirror-space can't be too strong compared to the lights inside the mirror-space, or it will overpower the effect. It's about finding the balance between blocking enough ambient light from entering to not ruin the effect, while still allowing enough light back out to see it. Luckily since it's CGI we can cheat a little... or a lot!
