Studio setup - Remove plane edge reflection

GGPS90 — Mon, 07 Jul 2014 11:03:08 GMT

Hi, I have this render of this phone, it's standing straight on a plane with a vray material plugged into a vray material wrapper and with white as background in environment. This way the plane is invisible but still catches shadow. The problem I have is that reflection from the plane edge. How would you go around to get a similar render with seamless white and shadows on the plane but no edge reflection of the plane on the phone itself?

Hi. Right-click the Plane object, go to Object Properties. Uncheck "Visible to Reflection/Refraction," but make sure "Visible to Camera" is checked.

Ok, that worked out but it also made the phone darker and the plane is no longer reflective. Thanks for the tip.

What about replacing the plane with a closed chamfer box, surrounding lights and camera?

Thats odd- the plane should still be reflective. This may be a Vray thing? I don't have it to test, but I've done one in Mental Ray (attached) You can see on the right the plane is reflected. On the left it still catches the shadow and relects the box, but doens't reflect the plane.

The phone will only be darker because there was a certain amount of white plane being reflected by the floor. So it's hard to have it both ways - not in the refelection, but also not making the phone brighter/lighter.

Another thing you could try, is making a very small square below the phone that reflects and catches the shadow, then make the rest of floor plane invisible to relect/refract.

Stefan's suggestion should work. The edges won't be as abrupt as seen in your render.

As ollyv mentioned, your phone's brightness and reflections will largely depend on the environment it reflects. On occasions, I use separate objects for the ground/background and reflection. For example, I would have a ground object that receives reflection the way you have it, but I turn off "visible to reflection" in the properties. Then I'd have another object invisble to camera and only visible in reflection. This is when I want to have a specific shape of reflection shown on the object, much like "white card" or "bounce card" setup in photography.

Ok, I did what you guys said, i get better result now, still need to tweak to get around some problems. Thanks for the help.
