Infinite reflections using two mirrors

Post by Allan L. » Tue Oct 03, 2017 12:30 am

This isn't really a FormZ related question, but I'll go ahead and post here anyway since that's the plugin I use.

I've created a set up of two parallel mirrored planes. In between I put some a some objects. The mirror in front of the camera is set to be hidden from camera and shadows but to keep it's reflections. The rendered output of these is what you'd expect, a series of reflections that theoretically should go to infinity. The problem is, that after several reflections, the image will darken until it becomes black. (also to be expected, since the light can only bounce so many times)

Attached is an image. Is there anyway to set this up so that the reflections do not get so dark so quickly? (I've already added emitters on the top and bottom planes of the enclosure but it still gets dark.

Any help will be appreciated.

What are your mirror mat settings? Have you tried with a metal Nd and K to make it really reflective?

I think the mirror mat I'm using is as reflective as it gets. Please see attached.

No, I haven't tried a metal with a special ND or K.

Other than material, is there any other setting that can be changed to increase the number of light bounces?

Unfortunately no, because it would be against Maxwell philosophy :( (so no complex settings for advanced users)

With ND at 100, don't forget to check also Force Fresnel 8)

Excellent! This does the trick. I should have known better than to ask for complex settings, knowing that Maxwell's philosophy is based on real materials and real light.

Thanks a bunch!
