simulating cat eyes (material) ?

Yes it is possible - there are several options

Yet Another Thread about Cycles Materials

After receiving a tip from another user on these boards in relation to my volumetric retroreflective material - I decided to create a non volumetric version (uses the incoming light path instead). Like all retroreflectors - to see the effect, the light source needs to be pretty much in line with the camera and object (either directly behind the camera - or directly in front). I have added a little bit of scatter so the angle isn’t critical - you will get some reflection when the light source i…

Cycles Volumetric Rendering

Been playing with the volumetric scatter node (especially the anisotropic setting) over the past few hours and came up with an interesting application. Cats eyes. If you set the anisotropic setting negative (say -1) - it backscatters the light back in the direction of the light source - just like a retro reflector does. I’m currently rendering an animation to show the effect better. I created a sphere with a glass node in the surface slot and a volumetric scatter node in the volume slot - se…

Another application - retro-reflective tape like you get on barriers, police cars, ambulances etc
