Is it possible to create or fake retroreflection in Blender?

Yes, just use Raytracing and crank up the RayMirror value and its Depth value.

Thanks Fligh %, I’ll give it a try.

For those who don’t know what retroreflection is here’s a very brief description: http://www.3m.com/intl/ca/english/centres/safety/personal_safety/retroreflection.html

Another idea is to use a normal mapped texture colourband with a REALLY small yellow dot in the middle of a black gradient.

Hmm - Hang on…

I mean this (BLEND FILE)

Each of the three planes has the same texture, only the middle one is turned to the camera.

Render the animation and see what happens as the spotlight passes over the tiles.

Cheers!

[Edit] Sorry - I meant a Shader colourband (Normal will reflect light to the viewer - Shader to the light source. More realistic that way!)) Blend file updated.

Hey thanks for taking the time to make a blend file Ammusionist. That works great, and so simple too!
